Workplace Investigations

There is no specific legislation regarding a workplace investigation. In general, an employer has the right to investigate incidents at the workplace based on their authority over employees. However, the investigative powers of the employer are among others limited by the general right to privacy, which is also enshrined in Collective Bargaining Agreement No. 81 of 26 April 2002 to protect the privacy of employees concerning the control of electronic online data. If there are official complaints by employees due to sexual harassment, bullying or violence at work,  well-being legislation provides a specific procedure. Also, upcoming whistleblower rules include some specifications for an investigation, but at the time of publication these are not yet final (we refer to is in more detail below). The information below is only valid for workplace investigations in the private sector. The public sector has a set of specific rules and principles, which are outside the scope of this chapter.

In Ireland, employees have a constitutional right and an implied contractual right to natural justice and fair procedures. If a workplace investigation is not conducted in accordance with these principles, an employee may allege that the investigation is fundamentally flawed. If such an allegation is made then an employee may seek recourse from the Workplace Relations Commission (WRC) or potentially the High Court. The WRC is the body in Ireland tasked with dealing with employment law-related claims, including unfair dismissal.

The constitutional rights that employees enjoy were specified in the Supreme Court case of Re Haughey in 1971. That case held that where proceedings may harm the reputation of a person, public bodies must afford certain basic protections of constitutional justice to a witness appearing before it. It further stated that article 40.3 of the Irish Constitution is a guarantee to the citizen of basic fairness of procedures. These protections, known as “Re Haughey rights” are implied in each contract of employment.

A Code of Practice was introduced in 2000, namely S.I. No. 146/2000 - Industrial Relations Act, 1990 (Code of Practice on Grievance and Disciplinary Procedures) (Declaration) Order, 2000 (the Code). The Code set out the procedures for dealing with grievances or disciplinary matters, which must comply with the general principles of natural justice and fair procedures and include:

• that employee grievances are fairly examined and processed;
• that details of any allegations or complaints are put to the employee concerned;
• that the employee concerned is allowed to respond fully to any such allegations or complaints;
• that the employee concerned is given the opportunity to avail of the right to be represented during the procedure; and
• that the employee concerned has the right to a fair and impartial determination of the issues concerned, taking into account any representations made by, or on behalf of, the employee and any other relevant or appropriate evidence, factors or circumstances.

Further Codes of Practice on the prevention and resolution of bullying at work and on dealing with sexual harassment and harassment at work were published in 2021 and 2022, respectively. The provisions of these codes are admissible in evidence before a court, the WRC and the Labour Court.

In addition to the above, the Data Protection Commission published Data Protection in the Workplace: Employer Guidance in April 2023.

All employers should have specific and up-to-date policies dealing with how workplace investigations will be carried out that are suitable for their organisation. These policies may vary, depending on the subject of the investigation and the size and type of employer. However, all should adhere to the principles identified above to ensure that a robust policy is in place and can be utilised.

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.

First, the employer should appoint an investigator or investigative team that will be responsible for conducting the investigation. Next, the employer or the investigators might think about communicating with the involved employees. It depends on the situation if this is a good idea or not. In general, it can be recommended that the employer is transparent towards the involved employees and openly communicates about the (start of the) investigation process. This is definitively the case if it is already clear that the involved employees are under scrutiny because of their actions. In this case, the actual investigation can begin with a hearing of the involved employees. However, if there is a risk that employees will hide or destroy evidence or will collude to prevent the employer from finding the truth, the investigation can also start without any communication. In this case, it would be better to start collecting evidence before hearing from the employees involved.

Investigations can start in multiple ways. They usually stem from an employee raising a grievance, a bullying complaint, or a possible protected disclosure. Investigations may also stem from the employer in a disciplinary context, or indeed can be commenced if an external complaint or issue is raised by a third party of the organisation.

The first thing the employer must consider is whether an investigation is necessary. It may be that the issue at hand can be resolved informally or is of such a nature that it cannot be investigated, either through a lack of detail or simply because the subject of the complaint is no longer an employee. Any such decision to investigate or not should be carefully documented.

The next step to determine is the nature of the investigation. It should be clear at the outset whether the investigation is simply a fact-gathering exercise or if the investigator will be tasked with making findings on the evidence. The distinction is significant as a fact-gathering investigation can proceed without prompting the full panoply of rights, but the basic principles of fairness should still be applied. A fact-gathering investigation should determine whether there is or is not, a case to answer. If a disciplinary hearing follows then the rights outlined in question 1 will apply at that stage. If it is a fact-finding investigation, the rights apply from the outset of the process. The employee who is required to respond to the issues (the respondent) should be fully aware of the extent of the investigation. The investigator appointed to do the investigation should be clear about what is expected of them.

If the employer believes an investigation is necessary, it should be acknowledged and started without delay. In particular, according to the Protected Disclosures legislation, a report should be acknowledged within seven days.

An employer should consider and identify the scope of the investigation and establish who will investigate the matter. Terms of reference under which the investigation will be carried out should be established by the employer and shared with the employee raising the issue (the complainant). An employer should not seek agreement on the terms, but invite commentary to ensure that the full scope of the investigation is captured within the terms of reference. Robust terms of reference that lay down the clear parameters of the investigation will assist the investigator and all parties involved in the process.

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]

In principle, you cannot unilaterally suspend an employee during a workplace investigation, as there is a risk of constructive dismissal (ie, wrongful termination of the employment contract by the unilateral modification of one of its essential elements). Consequences could include the payment of an indemnity in lieu of notice based on seniority as foreseen by the Employment Contracts Act, plus possible damages (three to 17 weeks remuneration if an unreasonable dismissal, plus alternative or additional damages based on real prejudice suffered). The parties can nevertheless agree on a suspension of the employment contract. In this scenario, the remuneration will still have to be paid. Furthermore, a suspension could be a sanction that follows the outcome of the investigation, but even then it will only be possible for a limited time (and a suspension without pay is usually only allowed by the courts for a maximum of three days). However, if the complaint is about sexual harassment, bullying or violence at work, the prevention advisor (see question 4) can recommend that the employer take certain actions, which in grave circumstances could lead to employee suspension. The suspended employee should continue to receive his pay if this occurs.

Workplace suspensions in Ireland are a contentious issue and can result in an employer defending injunction proceedings in the High Court before an investigation has started.

In the case of Governor and Company of the Bank of Ireland v Reilly, the judge stated: “The suspension of an employee, whether paid or unpaid, is an extremely serious measure which can cause irreparable damage to his or her reputation and standing."

In the 2023 case of O’Sullivan v HSE, the Supreme Court held that the Health Service Executive acted fairly and reasonably as an employer in suspending a consultant doctor after he had performed experiments on patients without their consent. This ruling overturned the Court of Appeal's earlier decision that previously found the suspension to be unlawful, as the consultant did not represent an immediate threat to the health of patients.

The Supreme Court considered whether the employer's decision to place the consultant on administrative leave met the test set out in the English case of Braganza v BP Shipping Limited & Anor. In that case, the court held that the decisionmaker's discretion would be limited "by concepts of good faith, honesty and genuineness and the need for absence of arbitrariness, capriciousness, perversity and irrationality."

In relying on the principles set out in the Braganza case, the Irish courts have reinforced the right of a decision-maker in an employment context to have discretionary power when implementing a suspension and that any decision to do so must be made honestly and in good faith. Employers should obtain legal advice when considering whether to suspend an employee in any circumstance.

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.

In general, there are no legal minimum qualifications, the employer can delegate the investigation task to anyone. Of course, it is strongly recommended to appoint someone who is not involved in the case and who can lead the investigation objectively with the necessary authority to take investigative measures.

However, in the specific case of an official complaint due to sexual harassment, violence or bullying at work, the investigation will be conducted by the prevention advisor for psychosocial aspects. Next, if the investigation is based on an internal whistleblowing report, there will have to be an independent reporting manager responsible for receiving the report, giving feedback to the whistleblower and ensuring a decent follow-up to the report. Logically, the reporting manager will lead the investigation in this case, but he can be assisted by other persons or a team who are bound by a duty of confidentiality.

An investigator does not have to hold any minimum qualifications. More often than not it is an employee's manager or HR manager who is carrying out the investigation. Crucially, the person carrying out the investigation must not be involved in the complaint, as an argument of bias could be made before the investigation begins. The investigator should also be of suitable seniority to the respondent and have the necessary skills and experience to carry out an investigation. If a recommendation by the investigator is made to progress the matter to a disciplinary process, which may in turn be the subject of the appeal, there should be adequate, neutral personnel within the organisation to deal with each stage. Again if the investigator and the disciplinary decisionmaker are the same person, an argument of bias will be made that will usually lead to a breach of fair procedures and any decision being unsustainable. Frequently, employers outsource the investigation to an external third party as there may simply not be adequate personnel within the organisation to carry out the process. Employers should ensure that within their policies the right to appoint an internal or external investigator is reserved.

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.

This is only possible if the employee claims that his or her rights (eg, the right to privacy) are violated by the investigation (but this will merely limit the investigation methods) or if he or she finds that the investigation constitutes an abuse of rights. In any case, it will be very hard for an employee to completely halt the investigation.

Arguably yes, but it is the exception rather than the rule and it will depend upon the circumstances of the case. Generally, courts would be slow to intervene in ongoing workplace investigations. However, an employee may seek injunctive relief to prevent an investigation if they can show that the investigation is being conducted in breach of a policy or breach of fair procedures to such an extent that there is no reasonable prospect that the investigation's outcome(s) could be sustainable.

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.

Employees cannot be forced by their employer to act as a witness. If they decide to nonetheless testify as a witness, they do not, in principle, have particular rights. If the employee puts himself in a difficult or even dangerous position to act as a witness, it is up to the employer to offer the necessary protection or take measures to prevent any harm (eg, by keeping the identity of the witness confidential or by planning the hearing at a place or time when the employees involved are not aware of it).  

However, this is not the case for whistleblowing reports, where a witness might be seen as a “facilitator” who can receive protection against any retaliation by the employer.

Also, workers who were direct witnesses to official allegations of sexual harassment, violence or bullying at work are protected against retaliation by the employer. This also applies to witnesses in court.

Yes, but a qualified yes. To deny an employee who is the respondent to the complaint the right to cross-examine the complainant during a workplace investigation may amount to a breach of fair procedures. This does not mean in practice that a complainant or witness will have to physically or virtually attend a meeting to be subjected to cross-examination. What usually happens, in practice, is that specific questions of the respondent are put to the witness by the investigator for them to respond. On occasion and depending on the circumstances, the witnesses may respond in writing.

Generally, if witnesses do not wish to participate in workplace investigations and they are not the witnesses from whom the complaint originated, there is little that can be done. An employee may not want to be seen as going against a colleague, which impacts the wider issue of staff morale. An employer cannot force them to participate. Also an employee who is the respondent should be careful about seeking to compel witnesses to attend. While the respondent may request support from a colleague to act as a witness, that colleague may view things differently, which can lead to further issues.

In any event, employees cannot be victimised or suffer any adverse treatment for having acted as a witness.

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]

Here, the investigation “collides” with the right to privacy of the persons involved.

First, the rules and principles of the GDPR will apply if personal data is involved. Therefore, the employer will have to find a data-processing ground, which could be his or her legitimate interest or the fact that the investigation could lead to legal proceedings, etc. The data processing should also be limited to what is proportionate and the data subjects should be informed. Due to this obligation, it is arguable that the GDPR policy already provides the necessary information for the employees not to jeopardise the investigation. In any case, data subjects should not be able to use their right to access data to ascertain the preliminary findings of the investigation (which are confidential) or any confidential identities involved (eg, in the whistleblower procedure, the identity of the report should be protected at all times).

Also, the employer should follow the procedure of Collective Bargaining Agreement No. 81 on searching the e-mails or computer files and internet searches of employees. This CBA limits the purposes for searches and lays down a double-phase procedure that needs to be followed if private data is involved. Next to this, the employer should also take into account the case law of the European Court of Human Rights, which only allows e-mail and computer searches based on the following:

• whether the employee has been notified of the possibility that the employer might take measures to monitor correspondence and the implementation of such measures;
• the extent of the monitoring and the degree of intrusion into the employee’s privacy (including a distinction between the monitoring of the flow or the content of the communications);
• whether the employer has provided legitimate reasons to justify monitoring of the communications and accessing of their actual content; and
• whether it would have been possible to establish a monitoring system based on less intrusive measures, the consequences of the monitoring for the employee who is subject to it, and whether the employee had been provided with adequate safeguards.

Next, if the employer wants to use camera images, the rules of Collective Bargaining Agreement No. 68 should have been followed when installing cameras. If not, the images might have been collected illegally.

Under the GDPR (General Data Protection Regulation), personal data must be processed lawfully, fairly and in a transparent manner in relation to the data subject. The Data Protection Commission published Data Protection in the Workplace: Employer Guidance in April 2023, which is a useful guide.

Employers should exercise caution when gathering physical evidence that may involve the use of CCTV or other surveillance practices. The Irish Court of Appeal in the case of Doolin v DPC examined the use by an employer of CCTV footage for disciplinary purposes and found such use constituted unlawful further processing. The original reason for processing the CCTV footage was to establish who was responsible for terrorist-related graffiti that was carved into a table in the staff tearoom. It subsequently transpired Mr Doolin, who was in no way connected to the graffiti incident, had accessed the tearoom for unauthorised breaks and a workplace investigation followed. The original reason for viewing the CCTV related to security, but further use of the CCTV footage in the disciplinary investigation was not related to the original reason. This case confirms that employers must have clear policies in place in compliance with both GDPR and the Data Protection Act 2018 specifying the purpose for which CCTV or any other monitoring system is being used. Not only that, but these policies must be communicated to employees specifying the use of such practices.

It is not only data about the investigation that must be processed fairly, but any retention of the data, which can only be further processed with good reason. It is a legitimate business reason to retain data to deal with any subsequent requests or appeals under various internal or statutory processes, provided employees have been advised of the relevant retention period.

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.

The employer is, in principle, not entitled to search the employee’s private possessions, except with the explicit consent of the employee. Digital files on the computer or laptop of an employee can be searched under the rules of CBA No. 81 (see question 7) and other privacy rules.  

The first consideration here is what constitutes "employees' possessions". More often than not, employees will be using employer property and there should be clear policies in place that specify company property.

The difficulty arises if an employee is using personal equipment such as a mobile phone for work purposes. While there may be specific applications dealing with work-related matters that are accessible by the employer remotely, some applications may be device-specific and that is where issues may arise. In such instances, it is not unreasonable to ask the employee to provide such information or consent to a search of their personal property. However, this is the exception rather than the rule and all other legitimate avenues of obtaining such information should be explored first. Further, such requests for information should not be a fishing expedition as an employee has a reasonable expectation of privacy at work, which must be balanced against the rights of the employer to run their business and protect the interests of their organisation.

A search of physical items such as a desk or drawers should only be conducted in exceptional circumstances, even where there is a clear, legitimate justification to search and the employee should be present at the search.

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]

If the investigation is based on a whistleblower report that falls under the scope of the upcoming rules, the investigators are bound by a strict duty of confidentiality, especially regarding the identity of the report. The rules also provide some procedural deadlines for feeding back to the reporter. Within seven days of receiving the report through an internal reporting channel, the reporting manager needs to send a receipt to the whistleblower. From that moment, the reporting manager has three months to investigate the report and give feedback and an adequate follow-up to the report. Next, the rules offer strong protection against any retaliatory measures the reporter may experience. Regardless, these rules are mostly intended to offer the necessary protection for whistleblowers and to ensure that companies take necessary investigative steps following a report, but they do not include much information about the actual procedure of the investigation besides certain deadlines, nor do they deal with other employees involved (or under investigation).

Most whistleblowing policies will include a section that provides for an initial assessment of the complaint as to whether it meets the definition of a protected disclosure. This assessment, which ought to be carried out by a designated person who has been appointed to deal with disclosures, is a useful tool as some matters which may be labelled as whistleblowing may fall under the grievance procedure.

Where there are grounds, an investigation will be commenced. Under the Protected Disclosures (Amendment) Act 2022, whistleblowers are protected from penalisation for having made a protected disclosure, under the Act.

Penalisation may include; suspension, lay-off or dismissal; demotion, loss of opportunity for promotion or withholding of promotion; transfer of duties, change of location or place of work; reduction in wages or change in working hours; the imposition or administering of any discipline, reprimand or other penalty (including a financial penalty); coercion, intimidation, harassment or ostracism; or discrimination, disadvantage or unfair treatment.

If an employee (which includes trainees, volunteers, and job applicants) alleges that they have suffered penalisation as a result of making a protected disclosure, they may apply to the Circuit Court for interim relief within 21 days of the date of the last act of penalisation by the employer.

A claim for penalisation may also be brought before the WRC within six months of the alleged act of penalisation. If an employee alleges that they were dismissed for having made a protected disclosure, the potential award that the WRC can make increases from the usual unfair dismissal cap of two years’ pay to up to five years’ gross pay, based on actual loss.

Where a complaint of whistleblowing is made, employers should ensure that they appoint investigators with the appropriate knowledge and expertise to deal with such a matter and comply with the time limits set by legislation.

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.

A workplace investigation is often a sensitive matter that requires necessary confidentiality to find out the truth discreetly and objectively. Nevertheless, there is often pressure from employees, trade unions or even the media and general public to be transparent and communicate about the case. From a legal perspective, it is not recommended to communicate openly about an ongoing investigation, as this can jeopardise the investigation or the possibility of taking disciplinary measures.

Whistleblower investigations will be bound by a strict duty of confidentiality regarding anything that could reveal the identity of the reporter.

In complaints due to sexual harassment, violence or bullying at work, the prevention adviser is bound by professional secrecy. Consequently, he or she may not disclose to third parties any information about individuals that have come to his or her knowledge in the performance of his or her duties. However, he or she still has the freedom to inform the people concerned to carry out his or her tasks in the procedure.

This will depend on the nature of the investigation but, generally, investigations should be conducted on a confidential basis. All who participate in the investigation should be informed and reminded that confidentiality is a paramount consideration taken very seriously. However, it should be borne in mind that confidentiality cannot be guaranteed by an employer as the respondent in an investigation is entitled to know who has made complaints against them. Furthermore, the respondent is entitled to cross-examine the complainant and any witnesses, although in practice this right is rarely invoked strictly and is facilitated by the investigator, with questions from the respondent being put to the complainant and other witnesses.

On occasion, a breach of confidentiality may warrant disciplinary action, but this will depend on the circumstances. Exceptions to the requirement to keep matters confidential will of course apply where employees seek support and advice from others such as companions, trade union representatives or legal advisors. It may also not be possible to maintain confidentiality where regulators or the authorities are informed of the investigation.

Also, confidentiality may not be maintained if it is in the interests of the employer to communicate the complaint and any subsequent investigation, for example on a health and safety basis.

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]

In general, the employee should be informed that there is an ongoing investigation (unless this could jeopardise the investigation, in which case disclosure could be postponed until this is no longer the situation). Next, before imposing measures or sanctions, the employee should be allowed to be heard or to give his or her version of the facts. Of course, the employee can only do this if he or she is aware of the facts being investigated. It is not necessary to give the employee a full insight into the investigation, only the necessary facts that allow him or her to offer a defence are sufficient.

Under the fair procedures outlined above, details of the allegations or complaints against the employee should be put to them to enable them to fully respond to the allegations raised. The employee should also be provided with any relevant policies pertaining to the allegations against them, along with all documentary evidence of the allegations and the specific terms of reference that define the scope of the investigation. The employee should also be informed of their right to be represented, see question 15.

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).

If the complainant made use of an internal whistleblowing procedure, confidentiality regarding the identity of a reporter is mandatory. Also, in other cases and for other involved persons (witnesses), it is recommended to keep their identity confidential to prevent the risk of intimidation or other negative consequences.

In complaints due to sexual harassment, violence or bullying at work, if the prevention adviser heard or took written statements from persons that were considered useful for the evaluation, these persons may remain anonymous.

The employee must, nevertheless, receive sufficient information to be able to offer a defence concerning the facts of which he or she is accused.

Failure by an employer to provide the identity of the complainant, witnesses or sources of information seriously impinges upon the employee's right to fair procedure and could result in a flawed investigation.

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 principle this is possible. However, these NDAs do have their limits and cannot prevent involved persons from, for example, bringing a legal claim or filing a report if they are legally entitled to do so. Under whistleblower rules, a reporter can even publish his or her complaint under certain circumstances.

There is no legislation regarding NDAs, but there is a Bill before the legislature proposing to “restrict the use of non-disclosure agreements as they relate to incidents of workplace sexual harassment and discrimination”. It is currently at the report stage. Whether it passes remains to be seen, but there has in recent times been strong criticism of the use of NDAs to cover up matters that ought to be fully investigated and dealt with in an organisation.

Settlement agreements, however they arise, may include confidentiality clauses which may, depending on the terms of the agreement, extend to the fact and substance of an investigation, but as in the UK an employee's right to make a protected disclosure or report a criminal offence cannot be waived by signing an NDA.

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.

If the investigation is conducted by a prevention advisor, the investigation and the prevention advisor are bound and protected by a professional duty of confidentiality.

It would be difficult to assert privilege over materials that relate to the investigation itself.

Privilege may arise before the instigation of an investigation where an employer may seek legal advice from their legal advisors over the initial complaint and appropriate next steps. Subject to the relevant tests being met, Legal Advice Privilege arises in respect of a confidential communication that takes place between a professionally qualified lawyer and a client. Who the client is will be of significant importance as they must be capable of giving instructions to their lawyer, on behalf of the employer. Caution should be exercised by employers if advice to "the client" is disseminated further within the business to other members of management. If such a scenario arises, then there is a risk that privilege may be waived and such material could be disclosable under a data subject access request. Litigation privilege arises with respect to confidential communications that take place between a lawyer or a client and a third party for the dominant purpose of preparing for litigation, whether existing or reasonably contemplated.

It is also prudent to consider whether an external investigator should have access to their own independent legal advisor, and the funding arrangements for such advice would have to be considered by the employer.

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.

An employee can be assisted by a member of a trade union. They are also free to consult a lawyer.

This depends on the nature of the investigation. If the complaint originates from an employee as a grievance, then the employee would have the right to representation during the investigation. Representation in this context is more akin to the right to be accompanied, as in the UK by either a colleague or trade union representative.

If the investigation is a fact-gathering investigation originating from the employer, then the employee would not have the right to be represented during the investigation. That right would apply only at any subsequent disciplinary hearing.

If the investigation is a fact-finding investigation as part of a disciplinary process originating from the employer, then the employee ought to be given the right to be represented at that investigation stage. Again the right is akin to the right to be accompanied. There was concern from employers that the right had been expanded to legal representation in disciplinary matters with the case of McKelvey v Irish Rail. However, the Supreme Court in that case clarified that the right to legal representation in disciplinary processes is only in exceptional circumstances.

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.

At the request of the involved employee, an employee can be assisted by a member of the trade union delegation, for example, during his or her hearing.

The works council should be informed of an investigation if there is a considerable impact on the company; this will only be the case if the investigation concerns a very serious, important or widespread issue. This information should be communicated as soon as possible and before measures are taken as a result of the investigation. This is only a right to information, not consultation. Moreover, members of the works council may be asked to respect their duty of confidentiality. However, as the enforcement of this duty of confidentiality is difficult, the timing of the information should be chosen wisely so it does not jeopardise the investigation.

This will depend on the agreement with the works council or trade union. The employee who is the respondent to the investigation may have views on their trade union being informed, aside from any agreement, which should be taken into account under GDPR provisions.

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.

There are no other mandatory support measures. However, an employer is free to offer additional support, for example, by granting leave from work. If tensions at the workplace are high, it may be a good idea to ask the employee under investigation to take some leave. Some companies also provide certain legal, moral or even psychological support. If the complaint concerns sexual harassment, bullying or violence at work, the prevention adviser can also recommend that the employer take additional measures to support certain employees.

Furthermore, under the whistleblower rules, an external reporting authority can grant any support measure (eg, legal advice or financial, technical, psychological or media-related, social support).

For complaints due to sexual harassment, violence or bullying at work, and if the facts are serious, the prevention adviser should, during the examination of the request and before giving his or her opinion to the employer, propose protective measures to the employer. These measures are necessary to avoid serious damage to the complainant's health or a significant deterioration in the situation (for example, causing opposing parties to commit criminal offences). The final decision on taking these measures rests with the employer. This means that the employer does not necessarily have to take the measures proposed by the prevention adviser. They may take other measures that provide an equivalent level of protection for the employee.

If an employee assistance programme is in place, an employee irrespective of their role in the investigation should be directed to the programme and encouraged to avail of the services. Investigations can become protracted and employees should be kept informed as to progress and what is required of them regarding participation. Regular checks of the health and well-being of employees should also be made. Even if such a programme is not in place, occasionally and depending on the issues giving rise to the investigation, it may be appropriate for the employer to cover the cost of counselling to a certain extent.

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]

If the investigation is not protected by confidentiality towards the employer (e.g. the prevention advisor cannot disclose confidential information to the employer), it could result in further measures taken by the employer or lead to a new investigation.

If an investigator finds other issues that are outside the scope of the terms of reference, these should not be ignored but equally should not be included as part of the investigation, as they are beyond the remit of the investigation that was established at the beginning. An investigator should identify the other matters that may require further action and report these to the employer separately so as not to conflate issues.

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.

This will depend on where the employee raises a grievance and the content of the grievance. If it is against the employer, the investigation can take this into account and continue from there. If the grievance is raised against the authorities, it will depend on the steps taken by the authorities.

If the subject of the grievance relates to the subject of the investigation, the employee should be reassured that all the matters that they wish to raise concerning the matter under investigation will be dealt with in full as part of the investigation.

If the employee raises a grievance that is unrelated to the matter under investigation, then that can be dealt with concurrently, albeit by a separate investigator.

The initial investigation does not automatically need to be halted upon receipt of a grievance. Frequently, grievances are submitted in the hope that they derail or delay the original investigation. Careful consideration should be given as to the nature of the grievance and the appropriate course of action adopted.

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).

If this occurs, there is a risk that any measure resulting from the investigation (eg, a dismissal) can be (wrongly) interpreted as discrimination based on the illness of the employee. However, if the employer can prove that the measure is not related to the illness but solely related to the investigation (which is also not related to the illness), there may be no discrimination. The sickness of the employee may prevent the continuation of the investigation because, for example, it becomes impossible to hear from the employee. In this instance, the investigation can be suspended, postponed or extendeded until the employee returns. If it is a long-term absence, this could lead to a disproportionate amount of time to complete the investigation. Therefore, the employer should take any necessary steps to invite the ill employee to a hearing anyway (eg, through digital means). If the employee unreasonably refuses (several) of these invitations, it could be argued that the employee is wilfully boycotting the investigation and therefore forfeits his or her opportunity to be heard.

If an employee goes off sick during the investigation, it is reasonable to adjourn the investigation until the employee is fit to return to work. Difficulties arise if it is a prolonged absence. The absence may necessitate a referral to an occupational health expert and it may be necessary to seek medical advice as to whether the employee can continue to participate in the investigation. It may be that reasonable accommodations should be considered to ensure that the employee can continue to participate. Such situations may impinge on the investigator's ability to conclude the investigation. In that instance, it would be prudent for the investigator to document all attempts to involve the employee in the investigation and to assess whether it can be concluded without the further involvement of the employee.

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).

In legal proceedings, a criminal procedure takes precedence over civil procedures. However, disciplinary internal proceedings (like a workplace investigation) and an investigation by the authorities may run parallel to each other. If the public investigation leads to a court procedure that results in the acquittal of the employee under investigation, it could lead to legal problems if the employer has already imposed sanctions based on the same employee. Therefore, the employer could make the internal investigation dependent on the public investigation, and could take preventive measures while awaiting the outcome.

The public authorities normally have the legal competence to request information that can help them in their investigation. Therefore, they could rightfully ask the employer to share evidence or findings from the internal investigation.

Workplace investigations can originate from criminal investigations or proceedings. It may be that an employer only becomes aware of a matter through the involvement of the police (An Garda Siochana) or regulatory bodies.

If a criminal investigation is pending it can complicate a workplace investigation, but it will be specific to the nature of the complaint. Likewise, where a regulatory investigation is in scope, an employee may argue that any internal investigation should be put on hold, on the basis that it will harm any regulatory investigation. Such matters will be dealt with on a case-by-case basis as it may be some time before any regulation investigation commences, by which time the workplace investigation and any subsequent process may have been concluded.

Employers will also have to consider their reporting obligations to An Garda Siochana. If the matter relates to fraud, misuse of public money, bribery, corruption or money laundering, for example, reporting obligations arise under section 19 of the Criminal Justice Act 2011. A failure to report information that an employer knows or believes might be of material assistance in preventing the commission of an offence, or assisting in the apprehension, prosecution or conviction of another person may be guilty of an offence.

Also, the Irish Central Bank's (Individual Accountability Framework) Act 2023 (the Act) was signed into law on 9 March 2023 but has not yet been enacted. The framework provides scope for a senior executive accountability regime, which will initially only apply to banks, insurers and certain MiFID firms. However, its application may be extended soon. The Act forces employers to engage in disciplinary action against those who may have breached specific "Conduct Standards".

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).

It is highly recommended to inform the employee under investigation of the outcome. If disciplinary measures are imposed upon him or her, the legal procedure must be followed and the sanction must be imposed or communicated the day after the employer or his delegate has established the wrongdoing of the employee.

The employee whose actions are the subject of the investigation must be advised of the outcome of the investigation. They are usually provided with a copy of the investigator's report.

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]

It is recommended to limit the communication to the findings and details of the report that are necessary for the employee to fully understand the outcome. This is especially true if the investigation is bound by a duty of confidentiality (eg, under the whistleblowing rules), as the employee should not be allowed access to the full report.

The investigation report should be shared in full, unless there is some specific reason for not doing so. One example is where there is a possibility of a criminal investigation; in that instance, it may be appropriate not to share the full report. Occasionally, there may be several respondents involved in the complaint, and each respondent may only be entitled to the report that relates to them.

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]

If the investigation leads to the establishment of grave errors by the employee, this can lead to sanctions. The employer must follow the procedure laid down in the internal work rules of the company and can only impose sanctions that are included in the internal work rules. In general, these are: a verbal warning; a written warning; a suspension (remunerated or not); a fine (capped to one-fifth of daily remuneration); and dismissal. If there are very serious errors leading to an immediate inability to continue the employment relationship with the employee, the employer can dismiss the employee with urgent cause without any notice period or indemnity in lieu of notice (following the specific procedure for these types of dismissals). In less serious cases, the employer could still dismiss the employee with a notice period or indemnity in lieu of notice. In principle, the employer has a right to dismiss the employee, even if this sanction is not included in the internal work rules.

As said previously, disciplinary sanctions (included in the internal work rules) must be communicated to the sanctioned employee the day after the employer or his delegate has established fault. The sanction must be registered in a sanction register, with the name of the employee, the date, the reason and the nature of the sanction. If there is a fine, the amount of the fine should be mentioned. The proceeds of the fines must be used for the benefit of employees. Where a works council exists, the use of the proceeds of the fines must be determined after consultation with it.

The investigator will usually set out recommendations within their report. It will then be up to the employer to act on those recommendations and to accept or reject the findings (if it were a fact-finding investigation). If, for example, a recommendation is made that the matter should proceed to a disciplinary hearing, the employer should then arrange such a hearing and nominate an impartial member of management to carry out the disciplinary hearing. In some instances, recommendations are made by investigators to provide training or update policies and such recommendations should be acted upon without delay. It may also be appropriate to notify a specific regulator of the outcome of the investigation.

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.

If the investigated acts constitute a crime, the authorities or the police should be informed. In certain cases, not doing so could lead to the company being accused of concealing a crime or becoming jointly responsible for it. However, if the company is the only victim of the crime and it is minor, the company may choose not to inform the authorities. For example, there is an enormous difference between a bank employee stealing large amounts of money from clients and an employee who is stealing toilet paper from the company. As stated above, the interview records could be at risk of disclosure if the authorities or police seize them for their investigation.

Depending on the nature of the subject matter of the investigation, it may be appropriate to notify the Garda Siochana or a specific government body such as Revenue. Also, if the employee occupies a regulated position, it may be necessary to inform the relevant regulator. Again, compliance with GDPR obligations should be borne in mind.

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]

According to the GDPR, personal data should only be stored for a proportionate amount of time. Usually, this means that it can be stored as long as it is relevant for the employment contract, and even afterwards, if there is a risk of legal proceedings (ie, regarding the dismissal of the employee).

Irrespective of the outcome of the investigation, the fact that an employee was subject to an investigation is not the key issue. The key concern is whether any further action was taken as a result of the investigation. If a disciplinary process ensued, then it is the outcome of that disciplinary record and any subsequent appeal that would or would not be noted on an employee's record. If a disciplinary sanction were imposed then the length of time the sanction remains on the employee's record would depend on what is specified in the disciplinary policy.

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]

In general, abusive investigations could lead to a legal claim regarding the abuse of rights. During an investigation, an employer should be guided by principles of due diligence and not take disproportionate action. If the investigation causes unnecessary damage, involved employees could file for compensation (eg, before the labour court). Next, the employer is also responsible for following the mandatory procedure for official complaints regarding sexual harassment, bullying and violence at work and investigations of whistleblower reports. In the first case, an employer who does not follow the procedure or obstructs the procedure can be liable for penal or administrative fines (maximum 8,000 euro) or, if the employer has not taken necessary measures to mitigate the risks for the employee and the employee suffers damage to their health, they may be liable for a fine of a maximum of 48,000 euro and imprisonment for between six months and three years. In the second case (whistleblower procedure), if an employer did not follow or has obstructed the procedure, they can be fined up to 5% of the annual revenue of the preceding year.

If the complaints involve allegations of sexual harassment, violence or bullying at work, the employer might risk an investigation of the inspection on supervision and well-being at work. If the prevention advisor finds out, before giving his advice, that the employer did not take any suitable protective measures after they were recommended, the prevention advisor is obliged to call an inspection on supervision and well-being at work.

A failure to follow fair procedures in the investigation can have significant consequences.

Although the exception rather than the rule, an employee could challenge the investigation through injunctive proceedings if there is a breach of fair procedures. Such action would be taken before the High Court. Injunction proceedings may be brought while the investigation is ongoing, or just before its conclusion to prevent publication of a report making specific findings against an employee. A successful injunction may curtail any subsequent attempt to investigate the matter as allegations of penalisation, prejudice and delay may arise.

Errors during the investigation can also give rise to a complaint of constructive dismissal, with allegations that flaws in the procedure have fundamentally breached the implied term of mutual trust and confidence.

A flawed investigation can also undermine any disciplinary process and sanction that is imposed as a result. This commonly occurs when an employee has been dismissed following a disciplinary process launched on foot of the investigation. While dismissal may be an appropriate sanction, the dismissal can still be found to be unfair if there is a failure to follow fair procedures. An employee may challenge their dismissal before the WRC and the employer should be alive to not only an unfair dismissal complaint, but allegations of discrimination and penalisation.

Overall, to carry out a successful workplace investigation, an employer should consider taking advice at the earliest opportunity to ensure that the investigation can withstand challenges.

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]
