Workplace Investigations

Dutch employment law does not provide for a timeframe within which an internal investigation must be launched. However, it is important for an employer who suspects abuse or irregularities, to start an internal investigation without delay. In essence, that means that as soon as management, or – depending on the specific circumstances – the person who is authorised to decide on disciplinary sanctions against a certain employee, becomes aware of a potential abuse or irregularity, all measures to initiate an internal investigation should be taken promptly. If this is not done, the employer may lose the opportunity to take certain disciplinary actions.

The legal framework relating to an investigation by an employer into the acts and omissions of an employee are determined by, among other things, section 7:611 of the Dutch Civil Code (DCC) that stipulates good employer practices; Section 7:660 DCC (right to give instructions to the employee); the European Convention on Human Rights; the Dutch Constitution; the General Data Processing Regulation; and, if the employer uses a private investigation agency, the Private Security Organisations and Detective Agencies Act and the Privacy Code of Conduct for Private Investigation Agencies.

The legal basis from which the employer derives the authority to investigate can be based on the employer's right to give instructions (section 7:660 DCC). Pursuant to this section, the employer has – to a certain extent – the right to give instructions to the employee “which are intended to promote good order in the undertaking of the employer”. In many cases, an investigation of a work-related incident will aim to promote good order within the company. As such, the investigation is trying to:

• find the truth;
• sanction the perpetrator; and
• prevent repetition.

Instructing an employee to cooperate with an internal investigation falls within the scope of the right to instruct.

Subsequently, the employer must behave as a good employer during the investigation, pursuant to section 7:611 DCC. This is coloured by the classic principles of careful investigation: the principle of justification, the principle of trust, the principle of proportionality, the principle of subsidiarity and the principle of equality. Furthermore, the principle of hearing both sides of the argument applies and there must be a concrete suspicion of wrongdoing.

There is no specific legal regulation for internal investigations in Switzerland. The legal framework is derived from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights. Depending on the context of the investigation, additional legal provisions may apply; for instance, additional provisions of the Swiss Federal Act on Data Protection or the Swiss Criminal Code.

In the United States, any combination of legislation at the federal, state and local level, as well as judicial opinions and regulatory guidance interpreting those statutes, may impose obligations on relevant employers to undertake a timely internal investigation in response to complaints of workplace misconduct and to promptly implement remedial measures, where appropriate.

An employer’s written policies often also set forth the company’s expectations for how its employees, partners, vendors, consultants or other third parties will conduct themselves in carrying out the business of the company, and these policies may include protocols setting forth the parameters for an investigation in the event of potential non-compliance. Such investigatory roadmaps are often described in, for example, employee handbooks or a company’s policy against discrimination and harassment.

Due to the patchwork nature of employment and related laws, it is not possible to cover every investigation scenario or related legislation in this guide. Employers should instead consult with experienced employment attorneys in their state to ensure compliance with the applicable legal and regulatory regimes. 

The workplace investigation can be exercised by an internal (ad hoc) investigation department of the company itself, for example under the direction of the internal audit department or compliance department. This is possible if there is sufficient manpower with the necessary independence, knowledge and experience. Case law, however, shows that courts tend to be more critical of internal investigations than external investigations. For more complex and sensitive investigations, a forensic accountant or lawyer is often involved. The advantage of involving a lawyer is that the investigation and its outcome are covered by privilege. This guarantees the confidentiality of the investigation, also regarding supervisors and investigating authorities. Yet, at the same time, there is increasing debate about the role of lawyers as investigators, given their inherent bias to work in the interests of their client (the employer).

The investigation starts with a plan of approach that must be signed by the contractor. This plan of approach outlines the legal framework of the investigation, such as the scope, the means to be used, how it will deal with data, the use of experts, how the interviews will be conducted, the way of reporting and confidentiality. Furthermore, there must be a protocol for how the investigator conducts the investigation and that applies to all parties involved.

Gathering information can be done in various ways. For example:

• An inventory can be made of the household effects of a company. In the event of theft, an inventory can be an appropriate means of establishing exactly what has been stolen.
• An investigation of the books: this is an investigation of all documents of the company. These are not private documents of employees, but documents of the company itself. For an investigator, an interview can be a good way to gather more information, for example by interviewing witnesses. In practice, there are almost always several interviews with the suspects, the employer and other people involved.
• Open source research, which often involves researching a person's social media, or public documents relevant to the research. In principle, “open sources” refers to all public documents in the world; nowadays, many public documents are digitised.
• A workplace search, which includes everything present in the workplace: diaries, computer files, e-mails, letters, and even the contents of a wastebasket.
• A digital data investigation: this is a frequently used tool in fraud investigations. Most communication and documents are digital nowadays. It is, therefore, very likely that evidence can be found in digital data. Each of these means of investigation must respect the principles of an internal investigation and comply with the GDPR principles .

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

A workplace investigation is often, although not always, prompted by a complaint of workplace misconduct, usually made directly by the employee who was harmed by the conduct, a third party who witnessed the conduct, or a manager or supervisor who was made aware of the issue and has reporting obligations as a result of his or her role in the organisation. 

It is best practice – and often a legal requirement depending on the applicable state law – for companies to clearly outline a complaint process in their policies and to provide employees who experience, have knowledge of, or witness incidents they believe to violate the company’s policies with one or more options for making a report. Although the specific complaint procedure may vary depending on the size of the organisation, the nature of the business and the type of complaint at issue, many companies provide for (or require) making a report through one of the following channels:

• a company-managed hotline or online equivalent;
•  human resources;
• an affected employee’s supervisor or manager; or
• a member of the legal or compliance department.    

Suspension is usually a disciplinary measure. The employer may, for example, suspend an employee if it is necessary that the employee doesn't work during the investigation into their actions or omissions. Suspension has no specific legal basis in Dutch law, but several conditions can be derived from case law or collective labour agreements.

Overriding interest

The measure may only be taken if the employee's presence at work would cause considerable harm to the employer's business or if, due to other compelling reasons that do not outweigh the employee's interests, the employer cannot reasonably be expected to tolerate the employee's continued presence at work. If there is a well-founded fear that the employee will (among other things) frustrate the investigation into their actions, the employer may proceed to suspend the employee.

Procedural rules

The principle of acting in line with good employment practice (section 7:611 DCC) plays an essential role in the question of the admissibility of the suspension. The principle of due care leads, among other things, to a duty of investigation for the employer and means the employer must enable the employee to respond adequately to any accusations.

Contractual arrangements

Many collective agreements or staff handbooks contain regulations on suspension and deactivation. The regulation may concern the grounds, the duration or the procedure to be followed. The latter includes rules on hearing both sides of the argument, the right to assistance, how the decision must be communicated to the person concerned, and the possibility of “internal appeal” and rehabilitation. Under good employment practice, the employer must proceed swiftly with the investigation and allow the employee to respond to the results. If the employee hinders the investigation in any way, it can be a reason to continue the suspension during the investigation.

Pay

In 2003, the Supreme Court ruled that suspension is a cause for non-performance of work that must reasonably be borne by the employer according to section 7:628 DCC. The employee has a right to be paid in nearly all circumstances, with limited exceptions (eg, if the employee is in detention and the employer suspended the employee in response to that).

Duration

The duration of the suspension during a workplace investigation is not legally pre-determined. However, the suspension of an employee must be a temporary measure. The relevant collective agreement often stipulates how long the suspension may last.

It is possible to suspend an employee during a workplace investigation.[1] While there are no limits on duration, the employee will remain entitled to full pay during this time.

Yes. An employer may suspend the subject of an internal investigation with full pay pending the outcome of an investigation. However, this measure should be used sparingly, for example in cases where an employee has been accused of gross misconduct or where it is the only means of separating the alleged victim of harassment from the accused to prevent continued harassment. As an alternative means of separating the victim from the accused, an employer can consider interim measures such as a schedule change, transfer or leave of absence for the alleged victim with his or her consent (employers should take care not to take any action that could be perceived as retaliatory against the complainant – even if well-intentioned – including involuntarily transferring him or her or forcing a leave of absence).

Where an employer does determine that suspending the subject of an investigation is warranted while the company carries out its investigation, it should provide him or her with a written statement briefly outlining the reason for the suspension and the estimated date the employee will be advised of the investigation outcome and his or her final employment status.

Workplace investigations, if they are to be of value, must be conducted by an expert, professional and independent party. To safeguard the independence of the investigation, it is crucial that neither the contractor nor any other third party can influence how the investigation is to be conducted or how the outcome should be reported. The investigation must be conducted according to the protocol drawn up at the start and the investigator must not be involved in the follow-up to the outcome.

There is an ongoing discussion of whether lawyers can conduct an objective and independent investigation, due to the bias inherent to their profession. On the other hand, investigation bureaus or committees are also not necessarily independent, as they are not regulated and not subject to disciplinary law.

The examinations can be carried out internally by designated internal employees, by external specialists, or by a combination thereof. The addition of external advisors is particularly recommended if the allegations are against an employee of a high hierarchical level[1], if the allegations concerned are quite substantive and, in any case, where an increased degree of independence is sought.

While every internal investigation should be carried out promptly, thoroughly and in a well-documented manner, employers should appoint one individual or team of individuals to oversee all complaints regardless of how they are received. Doing so helps to ensure that all allegations are documented, reviewed and assigned for investigation as consistently as practicable.

Once a complaint is received and recorded, the company should undertake an initial triage process to determine:

• the risk of the alleged misconduct from a reputational, operational and legal perspective;
• who is best suited to conduct an investigation based on the nature of the alleged misconduct and the perceived risk level (potential candidates may include members of human resources, legal or compliance departments, or outside counsel); and
• a plan for investigating the factual allegations raised in the complaint.

The appropriate investigator should be able to investigate objectively without bias (ie, the investigator cannot have a stake in the outcome, a personal relationship with the involved parties and the outcome of the investigation should not directly affect the investigator’s position within the organisation); has skills that include prior investigative knowledge and a working knowledge of employment laws; has strong interpersonal skills to build a rapport with the parties involved and to be perceived as neutral and fair; is detail-oriented; has the right temperament to conduct interviews; can be trusted to maintain confidentiality; is respected within the organisation; and can act as a credible witness.

At this triage stage, an employer may also wish to use the information collected from the complaint to proactively identify potential patterns or systemic issues at an individual, divisional or corporate level and react accordingly. For example, if a company receives a complaint against a supervisor for harassing conduct and that same individual has already been the subject of previous complaints, the company should consider whether it may be appropriate to engage outside counsel to carry out a new investigation to bring objectivity and lend credibility to the review – even if the prior complaints were not ultimately substantiated following thorough internal investigations. Similarly, the engagement of outside counsel is often appropriate where a complaint involves alleged misconduct on the part of a company’s senior management or board members.

Usually there is some kind of regulation in place as a result of which the employee is obliged to cooperate with the investigation. Nonetheless, there are examples whereby the employee refuses to cooperate. Especially in workplace investigations it will be hard to be able to conduct an investigation in such a situation.

There are, however, no possibilities for an employee to bring legal action in order or with the result to stop the investigation. 

The accused could theoretically request a court to stop the investigation, for instance, by arguing that there is no reason for the investigation and that the investigation infringes the employee's personality rights. However, if the employer can prove that there were grounds for reasonable suspicion and is conducting the investigation properly, it is unlikely that such a request would be successful.

In general, private sector employees have considerably fewer rights vis-à-vis a company-led internal investigation than their public sector counterparts. This is because many US states are “at will” employment states, which means that, absent an employment contract that provides otherwise, an employee can be terminated for any reason not prohibited by statute or public policy. Depending on the specific circumstances, however, an employee who is the subject of an internal investigation could bring or threaten legal action according to contract or tort principles to stop an investigation. An employee may also challenge an investigation because it was conducted in violation of certain federal, state or foreign laws, for example, the use of polygraph tests in violation of the Employee Polygraph Protection Act or foreign data privacy laws.

There is no statutory regime for employee witnesses in internal (workplace) investigations and, hence, no specific statutory regime for legal protection. However, as part of the idea that employees have to act in line with good employment practices (section 7:611 DCC), employees, who potentially acquired knowledge in a work-related context on the subject matter of an investigation, are typically required vis-à-vis their employer to participate in such internal investigations. The required degree of cooperation will depend on the type and nature of the investigation and the matter that is being investigated. The principle of “good employment practices” in turn requires the employer to be guided by proportionality and subsidiarity considerations: which information is relevant to the investigation and what is the least burdensome means of collecting such information?

This may also impact the degree to which an employer can involve employee witnesses in an investigation. Increased prudence should be observed, among other things, if the relevant employee witnesses may themselves become implicated in the investigation or when the employer envisages sharing certain investigative findings with regulatory or criminal authorities, for instance as part of cooperation arrangements in an ongoing investigation. In such cases, the relevant employee should at least be allowed to retain legal counsel before continuing interview procedures.

Due to the employee's duty of loyalty towards the employer and the employer's right to give instructions to its employees, employees generally must take part in an ongoing investigation and comply with any summons for questioning if the employer demands this (article 321d, Swiss Code of Obligations). If the employees refuse to participate, they generally are in breach of their statutory duties, which may lead to measures such as a termination of employment.

The question of whether employees may refuse to testify if they would have to incriminate themselves is disputed in legal doctrine.[1] However, according to legal doctrine, a right to refuse to testify exists if criminal conduct regarding the questioned employee or a relative (article 168 et seq, Swiss Criminal Procedure Code) is involved, and it cannot be ruled out that the investigation documentation may later end up with the prosecuting authorities (ie, where employees have a right to refuse to testify in criminal proceedings, they cannot be forced to incriminate themselves by answering questions in an internal investigation).[2]

Yes. The investigator is empowered to decide which witnesses should be interviewed as a part of the fact-gathering process. In addition to interviewing the complainant, the investigation should include individual interviews with other involved parties, including the subject of the complaint, as well as individuals who may have observed the alleged conduct or may have other relevant knowledge, including supervisors or other employees. Many companies’ code of conduct, employee handbook or similar policy set forth the requirement for current employees to cooperate fully in any investigation by the company or its external advisors and also provide that failure to do so could result in disciplinary action, up to and including termination.

In the absence of contractual protections, employees may have no legal right to refuse to submit to an interview, even if their answers tend to incriminate them. That being said, when acting as a witness in an internal investigation, a current employee is usually afforded similar legal protections as the subject of an investigation, including the right to oppose unreasonable intrusions into his or her privacy and unreasonable workplace searches. For example, certain state laws prohibit an employer from questioning an employee regarding issues that serve no business purpose.

Dutch data protection rules are based on the EU Data Protection Directive. The employer has to notify the Dutch Data Protection Authority when processing personal data as part of an internal investigation. Given that the notification can be accessed publicly, it is recommended that the employer give a sufficiently high-level description of the case. In addition, the description should be sufficiently broad to include the entire investigation, and any future expansions of the scope of the investigation. Often companies make filings for all future internal investigations, without referring to specific matters.

The employer has to notify employees whose personal data is being processed about – among other things – the purposes of the investigation and any other relevant information. According to the Dutch Data Protection Act, this information obligation may only be suspended on restricted grounds, i.e. if the purpose of the investigation is the prevention, detection and prosecution of crimes and postponement is necessary for the interests of the investigation (e.g., because there is a risk of losing evidence, or collusion by individuals coordinating responses before being interviewed)). These exceptions on the duty to inform involved persons must be interpreted very restrictively. As soon as the reason for postponement is no longer applicable (e.g., because the evidence has been secured), the individuals need to be informed.

Dutch data protection law does not require the consent of employees. Consent given by employees, however, also cannot compensate for a lack of legitimate purpose or unnecessary or disproportionate data processing, as the consent given by an employee to its employer is not considered to be voluntary given the inequality of power between them.

Furthermore, internal company policies may contain specific data protection rules.

The Swiss Federal Act on Data Protection applies to the gathering of evidence, in particular such collection must be lawful, transparent, reasonable and in good faith, and data security must be preserved.[1]

It can be derived from the duty to disclose and hand over benefits received and work produced (article 321b, Swiss Code of Obligations) as they belong to the employer.[2] The employer is, therefore, generally entitled to collect and process data connected with the end product of any work completely by an employee and associated with their business. However, it is prohibited by the Swiss Criminal Code to open a sealed document or consignment to gain knowledge of its contents without being authorised to do so (article 179 et seq, Swiss Criminal Code). Anyone who disseminates or makes use of information of which he or she has obtained knowledge by opening a sealed document or mailing not intended for him or her may become criminally liable (article 179 paragraph 1, Swiss Criminal Code).

It is advisable to state in internal regulations that the workplace might be searched as part of an internal investigation and in compliance with all applicable data protection rules if this is necessary as part of the investigation.

Documents and instruments that set out a company’s policies (eg, employee handbooks, code of conduct or other written guidelines) often contain provisions regarding employee data and document collection, workplace searches, communication monitoring, privacy, and confidentiality. As discussed below, state and federal constitutional, statutory and common law – and in some cases foreign data privacy regimes – may provide additional protections to protect employees from an unwarranted or unreasonable invasion of privacy during an internal investigation.

When conducting an internal investigation (which must have a legitimate purpose), the employer must act in accordance with the principles of proportionality and subsidiarity. In line with these principles, the means of collecting and processing personal data during an internal investigation as well as the data that is searched, collected or processed, should be adequate, relevant and not excessive given the purposes for which the data is being collected or subsequently processed. These principles can be complied with by, for example, using specific search terms when searching electronic data, limiting the investigation’s scope (subject matter, period, geographic locations) and, in principle, excluding an employee's private data.

The employer is, in principle, allowed to access documents, emails and internet connection history saved on computers that were provided to the employees to perform their duties, provided the requirements of proportionality and subsidiarity are taken into account. In other words, reading the employee's emails or searching electronic devices provided by the employer must serve a legitimate purpose (e.g. tracing suspected irregularities or abuse) and the manner of review or collecting and processing the data contained in such emails should be in accordance with the principles of proportionality and subsidiarity.

The employer can ask the employee to hand over an employee's USB stick for an investigation. Depending on company policies and (individual or collective) employment agreements, an employee is, in principle, not obliged to comply with such a request. A refusal from an employee, when there is a strong indication that this USB stick contains information that is relevant to an investigation into possible irregularities, may be to the disadvantage of an employee, for example in a dismissal case.

The following factors, which derive from the Bărbulescu judgment of the European Court of Human Rights, are relevant to the question of whether an employee's e-mail or internet use can be monitored:

• whether the employee has been informed in advance of (the nature of) the possible monitoring of correspondence and other communications by the employer;
• the extent of the monitoring and the seriousness of the intrusion into the employee's privacy;
• whether the employer has put forward legitimate grounds for justifying the monitoring;
• whether a monitoring system using less intrusive methods and measures would have been possible;
• the consequences of the monitoring for the employee; and
• whether the employee has been afforded adequate safeguards, in particular in the case of intrusive forms of monitoring.

These requirements can sometimes create a barrier for employers, as seen in a ruling by the District Court Midden-Nederland (16 December 2021, ECLI:NL:RBMNE:2021:6071) in which the employer had used information obtained from the employee's e-mail as the basis for a request for termination of the employment contract. In the proceedings, the employee argued that his employer did not have the authority to search his e-mail.

According to the District Court, it was unclear whether the employer had complied with the requirements of Bărbulescu regarding searching the employee's e-mail. The regulations submitted by the employer only described the processing of data flows within the organisation in general. Therefore, the District Court found that the employer did not have a (sufficient) e-mail and internet protocol and the employee was not properly informed that his employer could monitor him. In addition, according to the District Court, it was unclear what exactly prompted the employer to search the employee's e-mail, as the employer did not provide any insight into the nature and content of the investigation. As a result, the District Court was unable to determine whether the employer had legitimate grounds to search the employee's e-mail. On this basis, the District Court disregarded the (possibly) illegally obtained evidence and ruled against the employer's termination request.

The basic rule is that the employer may not search private data during internal investigations.

If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

As there is no unified data protection regime, privacy protections stem from a patchwork of federal and state privacy laws which impose limits on the extent to which an employer can collect information from its employees in connection with an internal investigation. Whether specific conduct violates an employee’s rights is a very fact-specific inquiry requiring the application of relevant state laws and a regulatory regime. 

In most circumstances, an employer is free to conduct searches of its workplace and computer systems in the course of investigating potential wrongdoing. Such searches are generally not protected by personal privacy laws because workspaces, computer systems and company-issued electronic devices are often considered company property. Many companies explicitly address this in written corporate policies and employment agreements. Employees who use their own electronic devices for work should be aware that work-related data stored on those devices is generally considered to belong to the employer (as a matter of best practice, employers should generally prohibit or at least advise employees against using personal devices for work and to maintain separate work devices, where possible).

These broad investigatory powers notwithstanding, the ability of an employer to conduct searches in furtherance of an internal investigation is not unlimited. For example, if an employer seeks to obtain or review work-related data from an employee’s personal device, the employer must be careful to exclude any personal data. Certain states also prohibit an employer from requiring an employee to disclose passwords or other credentials to his or her personal email and social networking accounts, but permit an employer to require employees to share the content of personal online accounts as necessary during an interview while investigating employee misconduct.

The former Act on the House for Whistleblowers already provided for several preconditions that a whistleblowing procedure must meet. For example, internal reporting lines must be laid down, as well as how the internal report is handled, and an obligation of confidentiality and the opportunity to consult an advisor in confidence must be applied. Employers are obliged to share the whistleblowing policy with employees, including information about the employee's legal protection. The employee who reports a suspicion of wrongdoing in good faith may not be disadvantaged in their legal position because of the report (section17e/ea Act House of Whistleblowers).

The starting point is that an employee must first report internally, unless this cannot reasonably be expected. If the employee does not report internally first, the House for Whistleblowers does not initiate an investigation. The House for Whistleblowers was established on 1 July 2016 and has two main tasks: advising employees on the steps to take and conducting an investigation in response to a report.

The Act on the Protection of Whistleblowers, which entered into force in 2023, introduced several changes, of which the most relevant are:

• Abolition of mandatory internal reporting: the obligation to report internally first is abolished. Direct external reporting is allowed, such as to the House for Whistleblowers or another competent authority. When reporting externally, the reporter retains his protection. However, reporting internally first remains preferable and will be encouraged by the employer as much as possible.
• Expansion of prohibition on detriment: the prohibition on detriment already included prejudicing the legal position of the reporter, such as suspension, dismissal, demotion, withholding of promotion, reduction of salary or change of work location. It now also includes all forms of disadvantage, such as being blacklisted, refusing to give a reference, bullying, intimidation and exclusion. 
• Stricter time limit requirements for internal reporting: the reporter must receive an acknowledgement of receipt of the report within seven days and the reporter must receive information from the employer on the assessment of their report within a reasonable period, not exceeding three months.

• Extension of the circle of protected persons: not just employees, but third parties who are in a working relationship with the employer are now also protected, such as freelancers, interns, volunteers, suppliers, shareholders, job applicants and involved family members and colleagues.

If an employee complains to his or her superiors about grievances or misconduct in the workplace and is subsequently dismissed, this may constitute an unlawful termination (article 336, Swiss Code of Obligations). However, the prerequisite for this is that the employee behaves in good faith, which is not the case if he or she is (partly) responsible for the grievance.

Several federal, state, and local employment laws prohibit retaliation against employees who come forward with complaints or participate in corporate investigations. Employees who possess information regarding corporate misconduct may also be considered whistleblowers protected from retaliation under federal and state whistleblower laws, including but not limited to the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, and the Consumer Financial Protection Act of 2010.

An employee generally does not need to show that he or she was terminated or demoted to bring a retaliation claim; other actions on the part of the employer may qualify if they could be seen to discourage employees from raising complaints. To protect against a potential retaliation claim, employers should make clear at the outset of an investigation that retaliation will not be tolerated and require the complaining employee (and potentially his or her manager) to bring any instances of retaliation to the investigator’s attention immediately.

The principle of due care requires employers to act prudently when it comes to sharing the identity of persons involved, such as complainants and implicated persons; and investigative findings, notably when certain employees may be implicated. As a result, such information is usually shared within an employer to designated departments on a need-to-know basis only. Additional safeguards as to the protection of whistleblowers' identities apply since the Whistleblower Directive (see question 9) was implemented in Dutch law. Also, see question 13 for the confidentiality obligations of employees vis-à-vis their employer.

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]

Information arising from the initial complaint, interviews and records should be kept as confidential as practically possible while still permitting a thorough investigation. Although an employer must maintain confidentiality to the best of its ability, it is often not possible to keep confidential the identity of the complainant or all information gathered through the investigation process. An employer should therefore not promise absolute confidentiality to any party involved in an internal investigation, including the complainant. The investigator should instead explain at the outset to the complaining party and all individuals involved that information gathered will be maintained in confidence to the extent possible, but that some information may be revealed to the accused or potential witnesses on a need-to-know basis to conduct a thorough and effective investigation.

An implicated person is typically provided with a summary description of the scope of the investigation and, hence, the allegations against such an employee (if any). This is usually done in the interview invite sent to the relevant interviewee, which also provides an opportunity to prepare for an interview and (if relevant) seek legal advice.

As a result of the employer's duty of care (article 328, Swiss Code of Obligations), employees under investigation have certain procedural rights. These include, in principle, the right of the accused to be heard. In this context, the accused has the right to be informed at the beginning of the questioning about the subject of the investigation and at least the main allegations and they must be allowed to share their view and provide exculpatory evidence.[1] The employer, on the other hand, is not obliged to provide the employee with existing evidence, documents, etc, before the start of the questioning.[2]

Covert investigations in which employees are involved in informal or even private conversations to induce them to provide statements are not compatible with the data-processing principles of good faith and the requirement of recognisability, according to article 4 of the Swiss Federal Act on Data Protection.[3]

Also, rights to information arise from the Swiss Federal Act on Data Protection. In principle, the right to information (article 8, Swiss Federal Act on Data Protection) is linked to a corresponding request for information by the concerned person and the existence of data collection within the meaning of article 3 (lit. g), Swiss Federal Act on Data Protection. Insofar as the documents from the internal investigation recognisably relate to a specific person, there is in principle a right to information concerning these documents. Subject to certain conditions, the right to information may be denied, restricted or postponed by law (article 9 paragraph 1, Swiss Federal Act on Data Protection). For example, such documents and reports may also affect the confidentiality and protection interests of third parties, such as other employees. Based on the employer's duty of care (article 328, Swiss Code of Obligations), the employer is required to protect them by taking appropriate measures (eg, by making appropriate redactions before handing out copies of the respective documents (article 9 paragraph 1 (lit. b), Swiss Federal Act on Data Protection)).[4] Furthermore, the employer may refuse, restrict or defer the provision of information where the company’s interests override the employee’s, and not disclose personal data to third parties (article 9 paragraph 4, Swiss Federal Act on Data Protection). The right to information is also not subject to the statute of limitations, and individuals may waive their right to information in advance (article 8 paragraph 6, Swiss Federal Act on Data Protection). If there are corresponding requests, the employer must generally grant access, or provide a substantiated decision on the restriction of the right of access, within 30 days (article 8 paragraph 5, Swiss Federal Act on Data Protection and article 1 paragraph 4, Ordinance to the Federal Act on Data Protection).

The investigator must disclose to the employee under investigation the purpose of the investigation and, where the investigator is in-house or outside counsel, he or she should disclose that the company is the client.

Such information can usually be kept confidential in an internal investigation, subject to potential disclosure obligations (see question 25). As indicated in question 10, depending on the nature and subject matter of an investigation, the identity of employees involved and investigative findings shall be shared with an employer on a need-to-know basis only. Specific requirements apply to the protection of the identity of whistleblowers since the Whistleblower Directive was implemented into Dutch law.

As mentioned under Question 10, the employer’s duty of care (article 328, Swiss Code of Obligations) also entails the employer’s duty to respect and protect the personality (including confidentiality and privacy) and integrity of employees (article 328 paragraph 1, Swiss Code of Obligations) and to take appropriate measures to protect them.

However, in combination with the right to be heard and the right to be informed regarding an investigation, the accused also has the right that incriminating evidence is presented to them throughout the investigation and that they can comment on it. For instance, this right includes disclosure of the persons accusing them and their concrete statements. Anonymisation or redaction of such statements is permissible if the interests of the persons incriminating the accused or the interests of the employer override the accused’ interests to be presented with the relevant documents or statements (see question 11; see also article 9 paragraphs 1 and 4, Swiss Federal Act on Data Protection). However, a careful assessment of interests is required, and these must be limited to what is necessary. In principle, a person accusing another person must take responsibility for their information and accept criticism from the person implicated by the information provided.[1]

In general, except as provided above, depending on the seriousness of the complaint and investigation, the only persons who should be aware of it are the relevant individual in human resources or legal, and where different, the persons assigned to investigate. Although it may not be feasible to maintain absolute confidentiality in conducting an investigation depending on the nature of the allegations, investigators should exercise discretion at all times and, where possible, avoid identifying complainants, the subject of the investigation or witnesses by name where it is not necessary, and where doing so could be detrimental to the fact-finding process.

Yes, NDAs can be used for this purpose. However, employers in the Netherlands often rely on general confidentiality obligations that the relevant employee already has to adhere to vis-à-vis their employer, for example in the employment agreement or collective labour agreement, if applicable. It is good practice to reiterate the confidential nature of any interview and its contents, and the existence of the investigation as such, to avoid any alleged confusion as to the confidential nature of investigative procedures later on.

In addition to the above-mentioned statutory confidentiality obligations, separate non-disclosure agreements can be signed. In an internal investigation, the employee should be expressly instructed to maintain confidentiality.

This is a fact-specific inquiry that depends on the specific circumstances and laws of the relevant state. In general, NDAs are frowned upon but can be used to an extent to keep certain facts and the substance of an investigation confidential. NDAs can never prevent employees from assisting in official agency investigations, however. NDAs also cannot lawfully prohibit employees from officially reporting illegal conduct by their employer.

If an attorney is engaged to provide legal advice or representation in respect of the (subject matter of the) investigation and as such also conducts (part of) the investigation, work products prepared by such an attorney will typically be subject to the legal privilege. Such work products may include, for example, interview minutes, investigation reports, investigation updates, attorney-client correspondence on the investigation, and legal advice rendered in connection with the (subject matter of the) investigation.

As outlined above, all employees generally have the right to know whether and what personal data is being or has been processed about them (article 8 paragraph 1, Swiss Federal Act on Data Protection; article 328b, Swiss Code of Obligations).

The employer may refuse, restrict or postpone the disclosure or inspection of internal investigation documents if a legal statute so provides, if such action is necessary because of overriding third-party interests (article 9 paragraph 1, Swiss Federal Act on Data Protection) or if the request for information is manifestly unfounded or malicious. Furthermore, a restriction is possible if overriding the self-interests of the responsible company requires such a measure and it also does not disclose the personal data to third parties. The employer or responsible party must justify its decision (article 9 paragraph 5, Swiss Federal Act on Data Protection).[1]

The scope of the disclosure of information must, therefore, be determined by carefully weighing the interests of all parties involved in the internal investigation.

For legal privilege to apply, a primary purpose of the investigation should be to provide legal advice to the company, including concerning non-lawyers working at the counsel’s direction, and legal privilege likely will not apply to internal investigations performed as part of the ordinary course of business or where the investigation is required by a state or federal regulatory regime (eg, post-incident investigations of operations governed by OSHA’s Process Safety Management Standards). It is, therefore, important to contemporaneously document the scope and purpose of the investigation and not risk waiving privilege by sharing privileged materials with unnecessary third parties.

Whereas attorney-client privilege includes only communications between an attorney and the client, work-product privilege is broader and includes materials prepared or collected by persons other than the attorney with an eye towards impending litigation. Examples of potential work products produced by attorneys in the context of an investigation include investigative work plans, interview outlines, memoranda summarising witness interviews and investigative reports.

As a practical matter, employees should be aware that communications with other employees or colleagues regarding the investigation are not privileged regardless of whether the colleague is also involved in the investigation or represented by the same counsel. Even if an employee believes he or she is sharing attorney communications with other employees who need to know the attorney’s advice and who also have attorney-client privilege with the same counsel because he or she is involved or implicated in the investigation and also represented by company counsel, it is always prudent to refrain from sharing privileged information. If an attorney’s communication is shared beyond those who need to know, attorney-client privilege may be destroyed.

All parties involved in the investigation have the right to a fair hearing. How this is embedded in the investigation should be laid down in the protocol drawn up at the start. When the employee, and others involved, receive an invitation for an interview in the context of an investigation, this invitation should include whether or not the employee has the right to bring legal representation to the interview. Given the unequal relationship between employer and employee, this will most likely be the case.

In the case of an employee involved in an internal investigation, a distinction must be made as to whether the employee is acting purely as an informant or whether there are conflicting interests between the company and the employee involved. If the employee is acting purely as an informant, the employee has, in principle, no right to be accompanied by their own legal representative.[1]

However, if there are conflicting interests between the company and the employee involved, when the employee is accused of any misconduct, the employee must be able to be accompanied by their own legal representative. For example, if the employee's conduct might potentially constitute a criminal offence, the involvement of a legal representative must be permitted.[2] Failure to allow an accused person to be accompanied by a legal representative during an internal investigation, even though the facts in question are relevant to criminal law, raises the question of the admissibility of statements made in a subsequent criminal proceeding. The principles of the Swiss Criminal Procedure Code cannot be undermined by alternatively collecting evidence in civil proceedings and thus circumventing the stricter rules applicable in criminal proceedings.[3]

In general, it is advisable to allow the involvement of a legal representative to increase the willingness of the employee involved to cooperate.

Employees generally have no automatic right to counsel in connection with an internal investigation, unless contractually provided for under the terms of an employment agreement. Nonetheless, employees may choose to retain counsel, particularly if they face liability.

There is, in principle, no role for the works council in an "isolated or single" internal investigation. When it comes to structural forms of employee monitoring to measure behaviour (such as video surveillance), the proposed decision to implement such a monitoring system in principle requires the prior approval of the works council.

In addition, according to the Act on the Protection of Whistleblowers,  an employer who is not obliged to set up a works council needs the consent of more than half of the employees when adopting the internal reporting procedure under theAct, unless the substance of the procedure has already been laid down in a collective bargaining agreement.

In general, works councils and trade unions are not very common in Switzerland and there are no statutory rules that would provide a works council or trade union a right to be informed or involved in an ongoing internal investigation. However, respective obligations might be foreseen in an applicable collective bargaining agreement, internal regulations or similar.

Employers generally have no obligation to inform employees of their right to union representation or to ask if they would like a union representative present during the interview. Union employees may insist, however, that a union representative attend any investigatory interview that could lead to the employee’s punishment, although the union representative may not interfere with the interview.

The employer can offer employees to be accompanied by another person, or by legal counsel, especially if the outcomes of the investigation could have consequences for their employment.

The employer does not generally need to provide specific support for employees that are subject to an internal investigation. The employer may, however, allow concerned employees to be accompanied by a trusted third party such as family members or friends.[1] These third parties will need to sign separate non-disclosure agreements before being involved in the internal investigation.

In addition, a company may appoint a so-called lawyer of confidence who has been approved by the employer and is thus subject to professional secrecy. This lawyer will not be involved in the internal investigation but may look after the concerned employees and give them confidential advice as well as inform them about their rights and obligations arising from the employment relationship.[2]

The employer’s counsel should provide an Upjohn warning at the start of any interview, and delivery of the warning should be documented by a note-taker. An Upjohn warning is the notice an attorney (in-house or outside counsel) provides a company employee to inform the employee that the attorney represents only the company and not the employee individually.

If the investigation yields unrelated matters, the employer will need to decide whether such matters should be followed up in the same or a separate investigation. If such matters include new allegations against an employee that are already involved in the investigation, the employer should, before interviewing (or at the start of such an interview) inform the implicated employees of the relevant new allegations that are the subject of the investigation.

There are no regulations in this regard in the Swiss employment law framework. However, in criminal proceedings, the rules regarding accidental findings apply (eg, article 243, Swiss Criminal Procedure Code for searches and examinations or article 278, Swiss Criminal Procedure Code for surveillance of post and telecommunications). In principle, accidental findings are usable, with the caveat of general prohibitions on the use of evidence.

Where new issues or claims arise during an ongoing workplace investigation, the investigator should discuss with in-house counsel whether the new issues or claims should be separately investigated and if so, by whom, or if instead those new issues or claims are sufficiently related to the current review that they can be investigated in parallel and incorporated into the ongoing fact-gathering process. 

There are a lot of possibilities for grievances that employees can raise during an investigation. A grievance, for instance, could be that a certain person is not interviewed, while the employee wanted this person to be interviewed in order to have a thorough investigation. In such a case the investigator needs to assess this grievance.

There is no general rule how to react to a grievance and there is also no general obligation to respond to a grievance. There needs to be a case by case assessment based on which further action is or isn't needed.

In the context of private internal investigations, grievances initially raised by the employee do not usually have an impact on the investigation.

However, if the employer terminates the employment contract due to a justified legal complaint raised by an employee, a court might consider the termination to be abusive and award the employee compensation in an amount to be determined by the court but not exceeding six months’ pay for the employee (article 336 paragraph 1 (lit. b) and article 337c paragraph 3, Swiss Code of Obligations). Furthermore, a termination by the employer may be challenged if it takes place without good cause following a complaint of discrimination by the employee to a superior or the initiation of proceedings before a conciliation board or a court by the employee (article 10, Federal Act on Gender Equality).

Where an employee who is the subject of a workplace investigation raises his or her grievance during the investigation, the investigator should follow the same steps outlined above to triage new issues or claims. The investigator should also discuss with in-house counsel whether any particular steps should be taken to avoid the perception that any disciplinary measures taken against the employee (in the event the original claims are substantiated) were retaliatory.

If the employee under investigation goes off sick during the investigation, they will generally be treated as a regular employee on sick leave, meaning they are entitled to continued salary payment and that both employer and employee have a reintegration obligation. This entails regular consults with the company doctor to determine how recovery progresses and when the employee can return to work. If the employer suspects that the employee is merely calling in sick to delay the investigation and such suspicion is not confirmed by the company doctor, the employer can ask the Employees Insurance Agency (UWV) to give a second opinion. When it is determined that the employee is in fact fit for work, the employer can oblige the employee to return to work and cooperate with the investigation. If the employee fails to comply, the employer can – after due warning – suspend the employee's salary payment.

The time spent on the internal investigation by the employee should be counted as working time[1]. The general statutory and internal company principles on sick leave apply. Sick leave for which the respective employee is not responsible must generally be compensated (article 324a paragraph 1 and article 324b, Swiss Code of Obligations). During certain periods of sick leave (blocking period), the employer may not ordinarily terminate the employment contract; however, immediate termination for cause remains possible.

The duration of the blocking period depends on the employee's seniority, amounting to 30 days in the employee's first year of service, 90 days in the employee's second to ninth year of service and 180 days thereafter (article 336c paragraph 1 (lit. c), Swiss Code of Obligations).

If an employee who is the subject of a workplace investigation becomes sick during the investigation, the investigator should complete as much of the process as possible in the employee’s absence, for example by conducting interviews with the complainant and other witnesses and collecting and reviewing relevant documentation. Where the employee’s absence is expected to be short-term, the employer can postpone completing the investigation until the employee returns to work and can be interviewed. Where a lengthy absence is expected, the investigator should take steps to ensure that the employee nevertheless has a fair chance to participate in the process, for example by providing the employee with flexibility in scheduling his or her interview or by offering other accommodations such as conducting the interview by video conference instead of requiring an in-person interview, or alternatively meeting in a neutral place instead of the office. It is important to maintain records of the steps taken to accommodate the employee to show that the process was reasonable and fair. 

In case there is a parallel criminal or regulatory investigation usually consultation between the investigators and the authorities takes place. Agreements are then sometimes made about the investigation conducted by / for the employer. In some cases, the authorities will ask to stay the investigation. There is no policy from the government on this topic.

There are situations where the authorities can compel the employer to share evidence. This depends on the exact circumstances of the case. For instance if the employer is the suspect in a criminal case.

It does occur that the authorities are given evidence upon request without the authorities having to order the extradition of evidence.  

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).

Employers have obligations to conduct a thorough and unbiased internal investigation and take prompt remedial action to prevent further workplace violations. As such, absent a criminal or regulatory investigation where the investigators ask the employer to pause an internal investigation, employers should be prepared to continue their internal investigation in parallel with the criminal or regulatory investigation while cooperating with police or regulatory investigators.

The police and the regulator can often compel the employer to share certain information gathered from its internal investigation. In some cases, the employer should analyse whether the non-disclosure of information evidencing criminal conduct within the company itself constitutes an independent crime or whether an applicable statute or regulation imposes an independent duty to disclose. Alternatively, the employer should consider whether, even absent an affirmative duty to disclose, disclosure of information gathered during an internal investigation may still benefit the employer.

There are no statutory requirements as to employee feedback in internal investigations. The principle of due care requires an employer to typically confront implicated persons with any allegations that concern them; and provide a draft report on their interviews for feedback, if the investigative findings will form the basis of disciplinary measures. It is good practice to also inform an employee under investigation once the investigation is closed.

Workplace investigations often result in an investigation report that is intended to serve as the basis for any measures to be taken by the company's decisionmakers.

The employee's right to information based on article 8, Swiss Federal Act on Data Protection also covers the investigation report, provided that the report and the data contained therein relate to the employee.[1] In principle, the employee concerned is entitled to receive a written copy of the entire investigation report free of charge (article 8 paragraph 5, Swiss Federal Act on Data Protection and article 1 et seq, Ordinance to the Federal Act on Data Protection). Redactions may be made where the interests of the company or third parties so require, but they are the exception and must be kept to a minimum.[2]

In general, it is often helpful to provide the complainant and subject of the complaint with a short written communication or verbal communication at the end of an investigation to advise that the investigation has concluded. Where the allegations are unsubstantiated, the communication should convey that no evidence of misconduct or unlawful conduct was found. Where the allegations are substantiated, the results and proposed communication should be reviewed with the legal function, together with potential disciplinary and remedial action, before it is communicated to the complainant and the subject of the complaint.

Where the misconduct alleged poses a high risk to the company from a reputational, operational or legal perspective, and especially where an investigation is conducted by outside counsel, outside counsel should determine, in consultation with the relevant individuals at the company, for example the general counsel, how and with whom to share investigation results and if and how to communicate the outcome to the complainant and the subject of the complaint. This is the case regardless of whether the allegations are found to be substantiated or unsubstantiated.

Employers are typically not required to share the investigation report with implicated persons or other employees involved in an investigation. Depending on the nature and subject of the investigation, the principle of due care may require an employer to share (draft) investigative findings before concluding on such findings.

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]

Only the findings should be shared with the complainant and the subject of the complaint.

A distinction can be made between a non-public reprimand and a public reprimand. A non-public reprimand is a warning from the employer to the employee that certain behaviour by the employee may not be repeated. This is a relatively light measure. The employer can apply this measure to behaviour for which a verbal warning is insufficient or has already been given (more than once). The employer should confirm the reprimand to the employee in writing, so that it forms part of the employee's personnel file. It is important to have an acknowledgement so there is no dispute as to whether the reprimand has reached the employee. Often, the letter will also mention the consequences if the employee continues to behave in this way, so that the employee is aware of them. The employer then has reasonable grounds to apply a more severe disciplinary measure, such as suspension or dismissal, should the behaviour be repeated.

For a public reprimand, the warning is also made known to third parties. This is, therefore, a more severe measure than a non-public reprimand, as the honour and reputation of the employee are affected. A public reprimand must, therefore, be proportionate to the seriousness of the behaviour and will only be possible in the event of a serious offence, for which a non-public warning will not suffice. A public reprimand is also more likely if it is necessary to prevent other employees from engaging in the same behaviour (deterrent effect). Given the impact on the employee, it is important that the employer carefully investigates the facts and allows the employee to tell their side of the story (hearing both sides of the argument). A public reprimand is rarely given.

If the outcome of the investigation is that the employee is culpable, the employer can request that the court dissolves the employment agreement for that reason. The employer will have to show that continuation of the employment agreement is no longer possible. If the court rules that the employee is culpable, the employment agreement will be dissolved, observing the relevant notice period and paying the statutory transition payment. Only if the court rules that the employee has shown serious culpable behaviour, will the notice period not be taken into account and the transition payment will not be due.

If the employee has come into contact with the judicial authorities or is suspected of a criminal offence, but has not been convicted or detained (yet), the employer – when requesting the dissolution of the employment contract – will have to make a plausible case that, based on this suspicion alone, it can no longer be reasonably expected that the employment contract is upheld. This may be the case in a situation where the offence the employee is suspected of has repercussions on the employer, colleagues or customers and relations of the employer. In this situation, the court will assess whether a less drastic measure than dismissal, such as suspension, is sufficient to the interests of the employer.

If there is still no conviction but the employee is unable to perform his or duties due to being detained, the court reviews a request for dissolution in the same way as above. In this case, if the employee's payment of wages is discontinued, justice may already have been done to the employer's interests.

The final stage involves the conviction and detention of the employee. Although the dissolution of the employment contract under section 7:669 (3) under h DCC – which includes conviction and detention – is the most obvious option, it is still necessary to assess whether termination of the employment contract is reasonable because of the employee's conviction and detention. Although the seriousness of the offence, the duration of the detention and how this reflects on the employer are important factors, the court also takes the age, duration of the employment contract and the position of the employee on the labour market into account.

The most far-reaching dismissal method that can be considered is instant dismissal for an urgent reason (section 7:678 paragraph 1 in conjunction with section 7:677 paragraph 1 DCC). According to the case law of the Dutch Supreme Court, the question of whether there are compelling reasons must be answered based on all the circumstances of the case – to be considered together – including the nature and seriousness of what the employer considers to be compelling reasons, the nature and duration of the employment, how the employee performed their duties and the personal circumstances of the employee, such as age and the consequences for the employee of an instant dismissal.

Mere suspicion of a criminal offence will not easily qualify as an urgent reason, as follows from jurisprudence. At the same time, an employer can, instead of criminal suspicion as grounds for dismissal, also base its claim on the behaviour that underlies it. If the behaviour of the employee is already factually established, for example, because the employee has disclosed it to their employer or the employer has established it, the employer does not have to wait for the criminal proceedings before dismissing the employee.

If the investigation uncovers misconduct, the question arises as to what steps should be taken. Of course, the severity of the misconduct and the damage caused play a significant role. Furthermore, it must be noted that the cooperation of the employee concerned may be of decisive importance for the outcome of the investigation. The possibilities are numerous, ranging, for example, from preventive measures to criminal complaints.[1]

If individual disciplinary actions are necessary, these may range from warnings to ordinary or immediate termination of employment.

Where the misconduct alleged is substantiated in whole or in part by an internal investigation, the human resources function, potentially in consultation with in-house or outside counsel, should agree on disciplinary or remedial action to be implemented.

The fundamental right to a fair hearing entails that the investigation findings must be disclosed to the employee under investigation at least once, so that they are given the opportunity to respond to them. Under Dutch administrative or criminal law, there are no general provisions requiring disclosure of investigative findings to regulators or criminal authorities. Certain specific provisions, however, apply, for example, in reportable incidents at financial institutions or certain HSE incidents that need to be disclosed to relevant regulatory authorities. Regulatory and criminal authorities, however, do have broad investigative powers enabling them to order the provision of data from subjects or involved parties in investigations they are conducting. Such information may also comprise investigation findings and underlying documents, such as interview records. If such interview records are subject to legal privilege (see question 14), they are typically not subject to disclosure to the relevant authorities.

Under Dutch civil law, a party that possesses certain records (such as investigation findings and underlying documents) is generally not required to disclose those to other parties for inspection. Parties are, in principle, not required to share information with third parties, other than relevant authorities (see above).

An exception to this rule is section 843a Dutch Code of Civil Procedure. Under section 843a, a party can be required to produce specific exhibits, if:

• the requesting party has a legitimate interest;
• the request concerns specific and well-defined records or information (ie, no fishing expeditions); and
• the documents pertain to a legal relationship (e.g., a contract or alleged tort; the requested party does not need to be a party to the relevant legal relationship).

If these requirements are met, the requestee should, in principle, disclose the requested information, except for specific exceptions. Such exceptions, which can also be relevant in the context of internal (workplace) investigations, could include confidentiality arrangements and privacy protection, to the extent that this would qualify as a compelling interest. To establish such a compelling interest, the relevant interest should outweigh the requesting party's legitimate interest regarding the requested information. This is a balancing act. Documents that are subject to legal privilege are protected against disclosure.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]

Once fact-finding is complete, the investigator should discuss his or her notes with in-house or outside counsel and prepare a summary of the process, high-level findings, and a proposed resolution at the counsel’s direction. This report should not include subjective commentary and should also avoid including excessive detail, and generally be treated confidentially during and after the investigation. If the report is requested by regulators or the police, the company should discuss with in-house counsel, and preferably also with outside counsel, how to respond to the request and whether any steps need to be taken to protect any applicable legal privilege.

The outcomes are usually kept in the records until termination of the employment agreement and only deleted when personal records are deleted.

From an employment law point of view, there is no statute of limitations on the employee's violations. Based on the specific circumstances (eg, damage incurred, type of violation, basis of trust or the position of the employee), a decision must be made as to the extent to which the outcome should remain on the record.

From a data protection point of view, only data that is in the interest of the employee (eg, to issue a reference letter) may be retained during the employment relationship. In principle, stored data must be deleted after the termination of the employment relationship. Longer retention may be justified if rights are still to be safeguarded or obligations are to be fulfilled in the future (eg, data needed regarding foreseeable legal proceedings, data required to issue a reference letter or data in relation to a non-competition clause).[1]

There is no requirement for the results of a workplace investigation to remain on an employee’s record for any specific period. It is often helpful, however, for information relating to the outcome of such an investigation (regardless of whether the allegations are substantiated) to be accessible to the human resources or legal functions such that during the initial complaint intake process described above, any prior complaints and investigations relating to the same individual or group of individuals can be taken into account to identify any recurring issues or systemic violations.

The employee can request compensation for violation of the right to a fair hearing or reputational damage. If the employee is suspended during the investigation, , the employee can request the court to order the employer to allow them to resume their work and request rehabilitation.

In termination proceedings (or after the termination of the employment agreement by the employer), the employee can claim an equitable compensation from the employer if the employer has shown serious culpable behaviour. Such compensation, if granted, is usually based on loss of income by the employee due to the behaviour of the employer.

As there are no specific regulations for internal investigations, the usual legal framework within which the employer must act towards the employee derives from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights.

But, for example, unwarranted surveillance could conceivably result in criminal liability (article 179 et seq, Swiss Criminal Code) for violations of the employee's privacy. Furthermore, errors made by the employer could have an impact on any later criminal proceedings (eg, in the form of prohibitions on the use of evidence).[1]

Evidence obtained unlawfully may only be used in civil proceedings if there is an overriding interest in establishing the truth (article 152 paragraph 2, Swiss Civil Procedure Code). Consequently, in each case, a balance must be struck between the individual’s interest in not using the evidence and in establishing the truth.[2] The question of the admissibility of evidence based on an unlawful invasion of privacy is a sensitive one – admissibility in this case is likely to be accepted only with restraint.[3] Since the parties in civil proceedings do not have any means of coercion at their disposal, it is not necessary, in contrast to criminal proceedings, to examine whether the evidence could also have been obtained by legal means.[4]

Unlawful action by the employer may also have consequences on future criminal proceedings: The prohibitions on exploitation (article 140 et seq, Swiss Criminal Procedure Code) apply a priori only to evidence obtained directly from public authorities. Evidence obtained unlawfully by private persons (ie, the employer) may also be used if it could have been lawfully obtained by the authority and if the interest in establishing the truth outweighs the interest of the individual in not using the evidence.[5] Art. 140 paragraph 1 Swiss Criminal Procure Code remains reserved: Evidence obtained in violation of Art. 140 paragraph 1 Swiss Criminal Procure Code is subject to an absolute ban on the use of evidence (e.g. evidence obtained under the use of torture[6]).[7]

The subject of the investigation, the complainant, or a government agency investigating the same alleged misconduct could subject the employer to legal exposure. It is, therefore, helpful for a company to prepare a contemporaneous report of the investigation that summarises: the incident or issues investigated, including dates; the parties involved; key factual and credibility findings; employer policies or guidelines and their applicability to the investigation; specific conclusions; the party (or parties) responsible for making the final determination; issues that could not be resolved through the internal investigation; and employer actions taken.

The employer should also maintain a clear record of the steps taken to investigate the alleged misconduct and any findings, as well as all evidence gathered during the investigation, including documents collected and reviewed, any work done to identify systemic issues or patterns of behaviour, and notes from all interviews, which should be limited to the facts gathered, dated and should indicate the duration and location of the interview.
