Workplace Investigations

Before commencing a workplace investigation, an employer must review the terms of any applicable employment contract, policy, procedure or industrial instrument. These documents will likely contain clauses that will dictate the investigation process.

There is also a significant body of common law that dictates how an investigation should be conducted and the procedural fairness that should be afforded to those involved. To ensure a workplace investigation is procedurally fair, employers must consider several factors, including:

• putting all allegations to the respondent in a manner which does not suggest a pre-determination of the outcome;
• conducting the investigation in a timely manner;
• providing the respondent with the opportunity to respond to the allegations;
• conducting a fair investigation process;
• making an unbiased (and not pre-determined) decision; and
• permitting the respondent and complainant to involve a support person or union representative.

Employers should also consider the additional steps they can take to conduct a best-practice investigation, including:

• being thorough and taking the time to plan the investigation;
• communicating clearly and fairly;
• considering whether the allegations are indicative of a wider workplace behaviour problem;
• maintaining confidentiality; and
• preventing victimisation.

Austrian law does not impose an obligation on employers to conduct internal investigations and they do not have to follow a specific legal pattern when doing so. However, an obligation to conduct internal investigations may arise out of certain provisions of criminal, company or even labour law – in particular, an indirect obligation arising from an employer's duty of care, which requires them to act against employee mistreatment, such as bullying.

If such internal investigations are initiated, compliance with labour law and data protection regulations is mandatory. According to section 16 of the Austrian Civil Code (ABGB), the employer must also protect the personal rights of the individual. It is important to emphasise that a company's internal investigation is a private measure and differs from official 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.

There is no specific law governing workplace investigations in Brazil, but Law 14.457/2022 states that companies must have rules that relate to sexual and other forms of harassment in their internal policies, address the rules for receiving and processing accusations, assess the facts, and discipline any individuals directly and indirectly involved in acts of sexual harassment or violence.

If the investigation has any connection with anticorruption matters, the investigation procedure must comply with Law 12846/2013 (Brazilian Anticorruption Act) and Decree 8420/2015.

As a result, Brazilian employers usually follow the rules determined by internal corporate policies, which often result from international regulations and principles that differ from the Brazilian ones, which inadvertently expose the Brazilian subsidiary to liability. The answers below will highlight common examples of this, when appropriate.

Currently there are no unified laws, administrative regulations or policies in the field of labor laws in People's Republic of China (referred to as “PRC”) regarding investigations on workplaces of ordinary employers. The laws and regulations of employers in certain specific industries (such as banking, securities, insurance, medical institutions, etc.) and the laws and regulations governing certain personnel (such as officers of state-owned enterprises and members of the Communist Party of China) contain provisions relating to investigations on employees' conduct, but such provisions are only applicable to the aforementioned specific industries or personnel.

Employers generally will specify their investigation rights and rules and procedures of internal investigations in their internal rules and regulations (such as the employee handbook) or the employment contracts entered into with their employees. However, it should be noted that workplace investigations are still subject to laws and regulations in relation to personal information, privacy and data protection.

Mainly, the Occupational Safety and Health Act (738/2002). In addition, the following also have relevance in connection to a workplace investigation: the Employment Contracts Act (55/2001), the Criminal Code (39/1889), the Act on Occupational Safety and Health Enforcement and Cooperation on Occupational Safety and Health at Workplaces (44/2006), the Act on Equality between Women and Men (609/1986) and the Non-discrimination Act (1325/2014). In addition, the employer's own policies must be taken into consideration while conducting a workplace investigation.

No specific rules directly govern a workplace investigation in the event of employee misconduct. However, several rules, both legal and administrative, affect the conduct of such an investigation. In addition, codes of conduct, internal regulations or guidelines may also exist within companies.

A new law (No. 2022-401) came into effect on 1 September 2022 and constitutes one of the cornerstones for future regulation of workplace investigations. This law transposes into French law the European directive relating to whistleblower protection. It does not, however, constitute a revolution, as a previous French law dated 9 December 2016 (the so-called Sapin 2 Law) already provided the whistleblower with a specific status and protection. These laws are fundamental when considering an internal investigation as the rules protecting the whistleblower and requiring the establishment of an internal whistleblowing channel (eg, a dedicated email or hotline) affect the degree of flexibility available to companies in conducting the investigation.

A new decree has been adopted (No. 2022-1284), dated 3 October 2022, for application of these new provisions. This decree sets out several obligations relating to the internal whistleblowing reporting process. The reporting channel will necessarily contribute to shape the internal investigation triggered by situations which have been reported by that channel. Companies subject to this decree may define the reporting procedure using the supporting tool of their choice (company collective agreement, internal memorandum, etc.), as long as the employee representative bodies are duly consulted on the matter. The decree also specifies that an acknowledgement of receipt of the alert must be provided to the author of the alert in writing within seven days from the company receiving the alert. The author of the alert must also be informed in writing, within a reasonable period not exceeding three months from acknowledgement of receipt of the alert, of the measures envisaged or taken to assess the accuracy of the allegations and, where appropriate, to remedy the situation which had been reported, as well as the reasons for these measures and, finally, the closure of the case.

More generally, not only do all the “pure” labour law rules relating to the protection of the human rights of employees need to be complied with (right to privacy, data protection under the GDPR, etc), but also the disciplinary rules and regulations that protect employees from unfounded sanctions imposed by their employer. For example, an employer can only sanction an employee's misconduct if the disciplinary procedure begins within two months of when the misconduct was committed or when the employer becomes aware of it. In this respect, an internal investigation can be necessary for the employer to obtain full knowledge of the facts alleged to have been committed by the employee. It is nonetheless recommended that the internal investigation be completed within these two months to avoid the risk of the disciplinary action being time-barred.

Administrative rules produced by the French anti-corruption agency should also be taken into consideration (good practice, guidelines and recommendations relating to senior management’s commitment to implement anti-corruption measures, corruption risk mapping, corruption risk management measures and procedures), as well as the guidelines produced by the French Ministry of Employment relating to the prevention of sexual harassment and gender-based violence or the recommendations of the Human Rights Defender, which is a French special institution aimed at protecting fundamental rights.

When the investigation in question concerns moral or sexual harassment or violence in the workplace, the national interprofessional agreement of 26 March 2010 should be <referred to. This text stipulates that in the event of an investigation procedure, it should be based on, but not limited to, the following guiding principles:

• it is in everyone's interest to act with the discretion necessary to protect everyone's dignity and privacy;
• no information, unless it is anonymized, should be divulged to parties not involved in the case in question;
• complaints must be investigated and dealt with without delay;
• all parties involved must be listened to impartially and treated fairly;
• complaints must be supported by detailed information;
• deliberate false accusations must not be tolerated, and may result in disciplinary action;
• external assistance may be useful, notably from occupational health services.

Many are calling for the adoption of legislative rules governing such investigations, and their coordination with general whistleblower protection measures.

Finally, a company must take its own rules and regulations into account. Every company with at least 50 employees has the legal obligation to draw up internal rules and regulations, which notably set out the disciplinary sanctions applicable to employees, as well as a reminder of certain employees' rights.

There are no specific legislative requirements for workplace investigations in Germany. In 2020, the Federal Ministry of Justice presented a draft bill with regulations on internal investigations and, in particular, employee interviews. However, this law failed to pass under the previous government. The current government has announced it will take up this matter again and plans to create a precise legal framework for internal investigations. Details, timing and content remain to be seen.

Nevertheless, workplace investigations do not take place in a "lawless space". They must comply with the provisions of employment and data protection law. Further, criminal and corporate law aspects can play a role. Moreover, works council information and co-determination rights may have to be taken into account.

In Greece, workplace investigations are not heavily regulated.

However, internal disciplinary procedures are governed by certain general principles, while there is also legislation regulating certain aspects of investigations opened in the context of whistleblowing procedures or concerning complaints for workplace violence or harassment. These include Law 4990/2022, which transposed EU Directive 2019/1937 into Greek Law; and Law 4808/2021, which ratified the ILO’s Violence and Harassment Convention, 2019 (No190) and introduced relevant provisions.

As far as disciplinary procedures in private-sector companies are concerned, employers that must have internal labour regulations in place (ie, those with more than 70 employees) or opt to adopt them voluntarily, can regulate the procedures themselves.  

In the public sector, internal investigations are governed by disciplinary provisions included in the civil servant code.

The Employment Ordinance (EO), which is the primary legislation governing employment relationships in Hong Kong, does not provide for a statutory workplace investigation procedure.

The Labour Department of Hong Kong has, however, published a Guide to Good People Management Practices[1] which recommends that employers lay down rules of conduct, grievance and disciplinary procedures. Such rules should be simple and clear, logical and fair, and in line with the provisions in the EO.

As part of risk management and internal controls, Hong Kong-listed companies are expected by The Stock Exchange of Hong Kong Limited (SEHK) to establish whistleblowing policies and systems for employees to raise concerns about possible improprieties with independent board members. Listed companies are also expected to establish policies for the promotion and support of anti-corruption laws and regulations. Such policies and systems may include workplace investigation procedures.[2] If a listed company chooses to not establish such policies and systems, it is required to explain how it could achieve appropriate and effective risk management and internal controls.

There is no codified law in India on conducting workplace investigations, so they largely depend on the internal policies of the employer. Certain requirements and best practice measures have evolved through judicial precedent, and these are codified through internal policies.

For claims involving sexual harassment, however, investigations can only be undertaken by the Internal Committee (IC), which an employer needs to constitute under the Prevention of Sexual Harassment of Women and Workplace (Prevention, Prohibition and Redressal) Act 2013 (SH Act).  

The general principle laid down by the courts is that any action against an employee for misconduct should be taken after conducting a disciplinary inquiry as per the principles of natural justice (PNJ). Whether or not a disciplinary inquiry can be done away with in any circumstances is a very fact-specific assessment and depends on various factors, including but not limited to the seniority and location of employment of the employee, and the nature and circumstances of the alleged misconduct.

The PNJ broadly require:

• that the accused employee should be issued with a written charge sheet or notice setting out the allegations against him or her along with a reasonable opportunity to respond;
• appointment of an independent inquiry officer to assess whether the allegations are proven or not; and
• that action must be taken based on the outcome of the inquiry, any punishment ordered should be proportionate to the gravity of the misconduct, and also take into account the service history (eg, prior warnings) of the individual.

The charge sheet or notice issued to the employee has to set out the evidence used by the employer to support the allegations in sufficient detail. Therefore, gathering necessary information and evidence is usually a critical precursor for any disciplinary process that an employer may eventually initiate against an employee.

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.

From an Italian employment law perspective, there is no specific body of legislation that governs investigations. However, several legal and case-law principles may be relevant concerning various specific aspects of investigations, and to which reference will be made below (eg, provisions under Law No. 300 of 1970, the so-called Workers’ Statute regarding “controls on employees”, both physical and “remote”, or regarding “disciplinary proceedings”).

In addition, and outside of the specific scope of employment law, other law provisions may have an impact on investigations, including those regarding privacy law (eg, Italian Legislative Decree No. 196 of 2003 and the Regulation (EU) No. 679 of 2016 (GDPR), regarding data protection and the related policies), whistleblowing (Law No. 179 of 2017 and Directive (EU) No. 1937 of 2019, regarding whistleblower protection) and criminal law (eg, Italian Criminal Procedure Code, providing rules for criminal investigation and Italian Legislative Decree No. 231 of 2001, regarding the corporate (criminal) liability of legal entities).

There is no specific legislation, guidance or policies covering investigations in the workplace. Issues such as the Personal Data Protection Law, invasion of privacy, and infringement of freedoms may arise regarding the related parties, subjects, methods, and results of investigations. In addition, court decisions have stated that "when there has been a violation of corporate order, an investigation of the facts may be conducted to clarify the nature of the violation, issue business instructions or orders necessary to restore the disturbed order or take disciplinary action against the violator as a sanction”. The investigation or order must be reasonable and necessary for the smooth operation of the enterprise, and the method and manner of the investigation or order must not be excessive or restrain an employee's personality or freedom. In such a case, the investigation may be considered to be illegal and may constitute a tort.

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 are essentially two phases in a workplace investigation: the fact-finding phase and the administrative proceeding.

The fact-finding phase of workplace investigations is usually governed by the internal policies of the employer, save for investigations relating to gender-based sexual harassment in the workplace. Republic Act No. 11313, otherwise known as the Safe Spaces Act, sets the parameters for these kinds of investigations.

Philippine case law recognises the right of an employer to conduct investigations for other acts of misconduct in the workplace in the exercise of its management prerogative. The Supreme Court has held that it is an employer’s right to investigate acts of wrongdoing by employees, and employees involved in such investigations cannot simply claim that employers are out to get them.

After the fact-finding aspect of the investigation, if the employer decides it has sufficient grounds to proceed to full-blown administrative proceedings, it needs to comply with the due process requirements outlined under the Philippine Labor Code. These requirements are:

• a first notice, or notice to explain, informing the employee of the charges against him or her;
• an opportunity for the employee to be heard; and
• a final notice on the outcome of the administrative action.

There is no legislation on this area in Poland. However, employers implement internal policies that provide for workplace investigation rules to fulfil certain legal obligations, including those arising directly from labour law.

Based on the currently binding provisions of labour law, an employer must counteract unwanted behaviour in the workplace (eg, bullying, discrimination and unequal treatment). To fulfil this obligation, employers implement internal policies that provide a framework for reporting misconduct and conducting internal investigations. They may freely design the rules of such investigations, within the constraints of their policy. Therefore, it is recommended they create the policy based on the following:
 

• it should be possible to effectively report the misconduct;
• there should be more than one way to report misconduct;
• anonymous reporting should be allowed;
• an investigation committee should be appointed and be objective;
• rules on excluding persons with a conflict of interest from conducting the investigation should be provided; and
• the report from the investigation should be prepared and signed by all persons participating in the process.

However, work on a bill on whistleblower protections is in progress (the Draft Law). The Draft Law will not determine the rules of workplace investigations but it will force employers to implement a whistleblowing procedure and follow-up on recommendations in the case of a report, including initiating an internal investigation where appropriate. Whether an internal investigation is initiated depends on the assessment of a reported irregularity by the employer.

In addition, employers (especially those that are part of an international group) often already implement internal policies on whistleblowing management and internal investigations. Employers often base their policies on guidelines issued by relevant (usually international) organisations.

Pursuant to article 98 of the Portuguese Labour Code, the employer has a disciplinary power over its employees during the employment period. This is enforced through the initiation of disciplinary procedures – which can include a preliminary workplace investigation as provided for in article 352(1) of the Portuguese Labour Code – and ultimately the application of sanctions laid down by law or in an applicable collective bargaining agreement.

The Portuguese Labour Code governs disciplinary procedures, which can include a preliminary workplace investigation, in two different sections. On the one hand, articles 328 to 332 establish general rules regarding the imposition of disciplinary sanctions; statutory deadlines and statutes of limitations involved; decision criteria; penalties; and disciplinary records. On the other hand, articles 351 to 358 lay down the rules applicable to dismissals with cause, which are also widely understood to be applicable concerning conservatory sanctions (i.e. those that enable the continuity of the employment relationship).

Additionally, collective bargaining agreements may provide for different disciplinary penalties, as long as the rights and guarantees of employees are not impaired.

Workplace investigations must also abide by the general rules laid down in the Portuguese Constitution, Portuguese Civil Code and Data Protection Laws (including guidelines issued by the Data Protection Agency), as regards the personal rights of the employees.

A workplace investigation is usually governed by the employer’s internal grievance policy or contractual guidelines found in the employment contract or employee handbook. In the absence of the same, the default governing regime is as set out by the Ministry of Manpower (MOM) and the Tripartite Alliance for Fair and Progressive Employment Practices (TAFEP) in its guidelines and advisories, which include:

• the Tripartite Advisory on Managing Workplace Harassment;
• the TAFEP Grievance Handling Handbook; and
• the Tripartite Guidelines on Fair Employment Practices.

In addition, section 14(1) of the Employment Act 1968 provides that an employer is required to conduct “due inquiry” before dismissing an employee covered under the Employment Act 1968 without notice for misconduct. The Singapore Courts take the view that “due inquiry” suggests some sort of process in which the employee concerned is informed about the allegations and the evidence against him or her so that he or she has an opportunity to defend him or herself with or without evidence during the investigation process.

Further, there are numerous cases where the Singapore High Court has alluded to or implicitly accepted the application of the implied term of mutual trust and confidence in employment contracts that would oblige the employer to act reasonably and fairly during the investigation, even though it is worth noting that the Singapore Court of Appeal has stated that the status of the implied term of mutual trust and confidence has not been settled in Singapore and that the Appellate Division of the Singapore High Court has stated that “[i]t remains an open question for the Court of Appeal to resolve in a more appropriate case, ideally with facts capable of bearing out a claim based directly on the existence of the implied term” (see [81]-[82] of Dong Wei v Shell Eastern Trading (Pte) Ltd and another [2022] SGHC(A) 8).

Hence, any references to the application of the implied term of mutual trust and confidence in Singapore in this article must be read in light of the above.

The current position is expected to change in the second half of 2024, with the passing of Singapore’s first workplace fairness law, the Workplace Fairness Legislation. On 4 August 2023, the Singapore government announced that it has accepted the final set of recommendations by the Tripartite Committee on Workplace Fairness in respect of the upcoming Workplace Fairness Legislation. The Tripartite Committee on Workplace Fairness recommended, among other things, that employers are required to put grievance-handling processes in place. It is therefore expected that the Workplace Fairness Legislation may contain requirements on how and when a workplace investigation should be conducted.

This article sets out the current position, before the Workplace Fairness Legislation was enacted, and will be updated when appropriate.

While there are no specific laws that regulate a workplace investigation, there are several laws that companies should consider when conducting a workplace investigation concerning alleged employee misconduct.

One key example is the Whistleblower Protection Act (WPA). The WPA provides legal protection to a whistleblower if their allegations are raised in good faith and are in the public interest as specified under the WPA. If the WPA applies, certain obligations apply to the company, including but not limited to the following:

• the obligation to protect the confidentiality of the whistleblower’s identity;
• protecting the whistleblower if the whistleblower suffers or is likely to suffer serious harm to life or health as a result of whistleblowing and the whistleblower requests protection; and
• refraining from taking retaliatory action on the whistleblower.

Therefore, if an employee raises allegations of another employee’s misconduct, the company should review whether the allegations fall under the WPA.

There are also special laws that impose obligations on the company if there are certain types of allegations (eg, sexual harassment, workplace harassment).

In addition, when collecting and reviewing employees’ electronic data, such as emails or files stored in work laptops or company servers, which may contain personal information, the company should comply with data privacy laws discussed in more detail in questions 7 and 8.

Companies may also have internal policies (eg, whistleblower protection policies, Code of Conduct) that may apply to workplace investigations, aside from the requirements under Korean law.

Spain has not passed any statutes, regulations or policies specifically governing workplace investigations. Instead, general employment and data protection legislation, which safeguards employees’ rights, is fully applicable during these types of enquiries.

These statutes focus on employee privacy. As a result, the application of this legislation:

• limits the matters that may be investigated: they have to be relevant to the employment relationship and there has to be a legitimate reason to conduct the enquiry;
• sets boundaries to the means that may be lawfully used by the company in the investigation: they must be the least intrusive means for employees’ rights (for instance, an email review should be a last resort, reserved for when less-invasive means are not available or would not be effective); and
• states that the companies’ decisions during the investigation must be proportional in light of the facts under review and the legal consequences attached to them.

Collective bargaining agreements, which in Spain generally apply to every company within their scope of application (normally a given economic sector), may regulate workplace investigations. However, it is unusual for collective bargaining agreements to regulate workplace investigations.

Finally, major international corporations with a presence in Spain do tend to have an ethics or whistleblowing policy that governs how an investigation should be conducted. Even if these are self-imposed policies, they are contractually binding and, once established, must be respected by companies.

Workplace investigations in Sweden are governed by several rules and regulations. Listed below are the central legislation and regulations that govern a workplace investigation related to alleged employee misconduct.

• The Swedish Discrimination Act (2008:567).
• The Swedish Work Environment Act (1977:1160), which is complemented by the Swedish Work Environment Authority’s other statutes.[1]
• The Swedish Whistleblowing Act (2021:890).

If a workplace investigation has been initiated after the receipt of a report filed through a reporting channel established under the Swedish Whistleblowing Act, that law applies provided that the report has been filed by a person who may report under the Act and provided that the subject of the report falls under the material scope of the Act. The Swedish Whistleblowing Act implements Directive (EU) 2019/1937 on the protection of persons who report breaches of Union law and has been given a wide material scope in Sweden. The Swedish Whistleblowing Act may apply if the reported irregularity concerns breaches of certain EU laws or if the reported irregularity is of public interest.

In addition to the regulations mentioned above, certain data protection legislation may affect workplace investigations by restricting what personal data may be processed. Such data protection legislation includes the following:

• Regulation (EU) 2016/679 on the protection of natural persons concerning the processing of personal data and the free movement of such data (the GDPR);
• the Swedish Supplementary Data Protection Act (2018:218);
• the Swedish Supplementary Data Protection Regulation (2018:219);

• Regulation DIFS:2018:2 on the processing of personal data relating to criminal convictions or offences. This regulation governs the processing of personal data relating to criminal convictions or suspected criminal offences in internal workplace investigations that are not governed by the Swedish Whistleblowing Act.[2]

The above-mentioned legislation and regulations may overlap in many aspects and it is therefore important before starting an investigation, as well as during an investigation, to assess which rules and regulations apply to the situation at hand. Another aspect of this is that many issues that can arise during an investigation are not regulated by law or other legislation. If the investigation is a non-whistleblowing investigation there are limited rules on exactly how and by whom the investigation should be carried out.

A Swedish law firm that undertakes a workplace investigation also has to adhere to the Swedish Bar Association’s Code of Conduct. The Code of Conduct includes additional considerations, mainly ethical, which will not be addressed in this submission. Furthermore, this submission will not focus on investigations following an employee’s possible misappropriation of proprietary information or breach of the Swedish Trade Secrets Act (2018:558). Investigations into such irregularities are often conducted to gather evidence and these investigations include the same or similar investigative measures used in other investigations, such as interviews with employees and IT-forensic searches, but also infringement investigations carried out by the authorities or other measures by the police.

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.

The Labour Protection Act B.E. 2541 (1998) (LPA) is the key legislation governing the relationship between employer and employee in Thailand. The LPA set out a minimum standard for the protection of employees’ rights, as well as a mechanism for suspension from work for an investigation.

The LPA requires any employer having ten or more employees to prepare work rules in the Thai language and the work rules require an employer to prescribe a procedure for the submission of grievances that would normally include the process for investigations in the workplace. Therefore, the work rules are the main guidance and policy that govern a workplace investigation. In some cases, an employer may have a whistleblowing policy allowing whistle-blowers to submit complaints of illegal or improper activities to the employer. The whistleblowing policy will also prescribe the procedures for investigating in workplace reflecting the complaints submitted by whistle-blowers.

There is no specific legislation governing workplace investigations in Turkish law. However, there are general principles stemming from Labour Law No. 4857 as well as good practice principles. Data protection laws also occasionally intertwine with these. The internal codes and policies of the company should also be followed throughout the process.

In the UK, the primary employment legislation of relevance to a workplace investigation includes the Employment Rights Act 1996 (ERA 1996), the Equality Act 2010 (EA 2010), and the Employment Relations Act 1999 (ERA 1999).

Other legislation includes the retained EU law version of the General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018 (DPA 2018), the Investigatory Powers Act 2016 (IPA 2016) and the Investigatory Powers (Interception by Businesses etc for Monitoring and Record-keeping Purposes) Regulations 2018 (IP Regs 2018), and the Humans Rights Act 1998 (HRA 1998).

In terms of guidance, the Advisory, Conciliation and Arbitration Service (ACAS) have produced a Code of Practice on Disciplinary and Grievance Procedures (the ACAS Code) as well as a Guide to conducting workplace investigations. The Information Commissioner’s Office (ICO) have their Employment Practices Code,  and other pieces of guidance on the data protection aspects of investigations (see question 7).

Most employers will have internal policies governing how workplace investigations should be conducted. The level of detail may vary considerably; public sector and regulated employers may be more prescriptive in their policies, which may even have contractual force. There may also be provisions of the employment contract that are relevant (particularly as regards suspension – see question 3).

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. 

There are no specific legislative requirements for workplace investigations in Vietnam. However, Labor Code No. 45/2019/QH14 dated 20 November 2019 (2019 Labor Code), which is currently the primary legislation governing employment relationships, requires employers that have more than ten employees to provide a mechanism and procedure for handling sexual harassment cases in the workplace. Other than that, an employer may incorporate policies and guidelines on how to deal with workplace investigations into its handbook.

It is not uncommon for respondents to an investigation to take personal or carer’s leave (sick leave) claiming that they are suffering from stress or anxiety. If this occurs, employers need to act appropriately, but this does not necessarily involve stopping the investigation process.

Employers should:

• assess the medical evidence to ascertain the respondent’s condition and determine how long they are likely to be unwell;
• avoid exacerbating the condition;
• determine whether the employee is unfit to attend the investigation meeting;
• take into consideration the evidence of other witnesses;
• consider delaying the investigation for a short period; and
• consider conducting the interviews in other ways, for example, in writing.

While all efforts should be made to accommodate an employee who has taken personal or carer’s leave during an investigation, if the respondent does not participate in the investigation, the investigation report may be prepared based on the available evidence.

The involved employee's sick leave does not affect the internal investigation. Most investigative measures can be carried out without the employee's presence.

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.

Sick leave suspends the employment agreement, and as a rule the employee should not be contacted during such a suspension. The investigation may continue without the participation of the investigated employee while that employee is absent, have its conclusion suspended while he or she is on leave, and resume once the employee returns to work.

During the investigation, the employer should fully respect the basic labor rights of the employee. According to the relevant provisions of Labor Contract Law of the PRC, if an employee is sick during the investigation, the employer should permit him/her to take sick leave provided that he/she provides the medical certificate issued by the medical institution and performs the medical leave application procedure as required by the employer. Therefore, the employer usually needs to request the employee to cooperate with the investigation after the sick leave, and cannot force the investigation by means of coercion or violence.

However, for the contents that can be investigated by the employer alone, such as the information publicized by the employee on social media and the employee's relevant information publicized on official website, since the investigation of such information is not affected by the employee's physical condition, the employer may adjust the investigation plan and conduct such part of the investigation first.

As a general rule, sick leave does not prevent an investigation from progressing. Depending on the nature of the sickness, the employee can attend hearings and take part in the procedure. If the sickness prevents the employee from participating, the employer can put the process on hold temporarily.

The investigation will likely be able to continue with the other employees and, as soon as the employee under investigation returns from sick leave, they will be able to be interviewed.

However, as disciplinary sanctions are time-barred after two months from the moment the misconduct was committed or from when the employer becomes aware of it, if the sick leave lasts for the whole of that period, the investigation must be conducted anyway. In this instance, the investigator can ask the employee to attend the interview despite being on sick leave or arrange for the interview to take place using other means (eg, conference call). As a last resort, a questionnaire can be sent to the employee, but the pros and cons must be assessed as this is a way of information gathering that carries a certain amount of risk, could be less reliable and is of less probative value.

Workplace investigations that do not require the presence or active cooperation of the employee may also start or continue during the employee's absence due to illness. If the employee's cooperation is required, for example for an interview, the employer can only instruct the employee to participate despite an existing illness if certain narrow conditions are met:

Regarding staff meetings at the company, the German Federal Labour Court has ruled that the employer can only instruct the employee to attend the staff meeting during illness if

• there is an urgent operational reason for doing so, which does not allow the instruction to be postponed until after the end of the incapacity to work; and
• the employee's presence at the company is urgently required and can be expected of him.

Similar rules are likely to apply to the employee's presence for workplace investigations.

Urgent operational reasons that cannot be postponed could exist, for example, if during the employee's absence due to illness, there is a risk that evidence will be lost (eg, where only the employee affected has access to certain files or data) or there is a risk of significant damage to the employer if workplace investigations are stopped until after the employee's return.

In principle, the health of an ordinary employee would not prevent the investigation procedure from taking place (eg, interviews with witnesses or the collection of evidence would not be postponed or suspended). However, if the employee under investigation is unwell and they can't participate in the procedure, the investigation may be suspended or postponed until the employee can take part. Bearing in mind the majority of company internal policies and regulations governing workplace investigations provide for a specific framework and timetable for the whole procedure to be completed, the long-term sickness of an employee under investigation may impede the completion of the procedure in the prescribed time. As a result, the person conducting the investigation may seek alternative measures to facilitate participation (eg, teleconferencing).

On a related note, if sickness occurs after the investigation is completed and the employer decides upon the imposition of disciplinary measures against the said employee and the initiation of a relevant procedure, the decision should be duly and timely communicated to the employee, irrespective of whether his or her presence in the workplace is not possible because of the illness.

If the employee under investigation goes off sick, the employer should ascertain the medical condition of the employee and when he or she is likely to return to fitness. If the employee is unlikely to return to work for a reasonable time, the employer should consider what adjustments can be made to the investigation process to continue with the investigation. If the employee’s input is necessary for the conclusion of the investigation, the employer may invite the employee to provide information by way of a written questionnaire or to attend a virtual meeting. However, the employee may not necessarily agree to these proposals, especially if he or she is unwell. In such circumstances, the employer may not be able to conclude the investigation in the absence of the employee.

The approach to be adopted would be fact-specific but the investigation itself can normally continue, even in the absence of the accused employee. Where it is critical to speak with the employee as part of the investigative process, delays on account of the employee's sickness may need to be accommodated. At the same time, the employer would normally be justified in seeking necessary evidence of the authenticity of the employee's illness and anticipated duration of absence. An accused individual's participation would be more crucial in a disciplinary inquiry to formally respond to the written charges or present their side before the inquiry officer, and absences due to genuine health concerns may need to be reasonably accommodated. Significantly long periods of absence for health reasons may itself be valid grounds to terminate employment under Indian law, subject to the terms and conditions of employment.

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.

Although there are no specific rules stating an investigation must be suspended if the employee under investigation goes off sick, practically speaking, this may slow down the process. Indeed, the employer would not be in the position to “force” the employee, while he or she is absent from work, to physically attend meetings, although they may ask for the employee’s availability to attend remote interviews (eg, via videoconference).

There is case law regarding an employee’s sickness during a disciplinary procedure (i.e. the procedure described above in point 3): according to certain rulings, if an employee, as per his or her rights, asks to submit an oral defence, but then falls sick, this does not prevent the employer from completing the procedure (and taking disciplinary action), unless the employee proves that his or her sickness prevents him or her from physically attending the meeting (being said that, above all if the procedure ends with a dismissal, a case-by-case analysis on how to manage such situations is highly recommended).

The company will seek a physician's diagnosis and opinion and determine whether to proceed with the investigation. If an employee’s mental health suffers because of the investigation, the company may be charged with a violation of its duty of care.

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 investigation would be suspended until the employee returns from sick leave. The investigation will immediately restart upon the return of the employee.

Since neither consent nor the presence of the employee is material to the conduct of the investigation, his or her absence would not, in practice, imperil the conduct of the investigation.

As previously discussed, because the employer exercises a wide latitude of discretion in conducting workplace investigations, the employer may choose to proceed with the investigation despite the absence of the employee being investigated. Since the proceeding is only in the investigation phase, the statutory right of the employee to be heard is not violated, even if the investigation takes place without his or her participation.

This may prolong the investigation, as the employee may be unable to participate for a time (if the employee is not able to work, in many cases he or she will not be able to participate in proceedings that requires some level of engagement and psychophysical ability). Also, an employee is protected against termination of an employment contract with notice during sick leave. During such a period, the employer may only terminate his or her employment contract without notice (with immediate effect).

The employer will be able to proceed with the investigation or disciplinary procedure regardless, although if it is necessary to hear the employee and they are unable to attend the interview, either the employer waits for their return or it could also send a written questionnaire for the employee to complete.

If the employee under investigation has already responded to the allegations made against him or her and his or her participation is no longer required at this stage in the investigation, the employer may proceed with the investigation even while the employee is off sick.   

However, if the employee under investigation has not responded to the allegations made against him or her and his or her participation is still required in the investigation, the company may exercise its discretion to pause the investigation until the employee can assist in the investigations.  To prevent an employee from using a medical condition as an excuse to delay or avoid the investigation, the company may require the employee to provide specific medical documentation to address the issue of the employee’s ability to participate in the investigation and to adjust the investigation process accordingly. For instance, instead of scheduling an in-person interview, the company may send a list of written questions for the employee to answer, and may also extend timelines for responding, etc.   

If the employee is unable to return to work for the foreseeable future, the employer may consider reaching a provisional outcome based on the available evidence, which would be subject to change when the employee under investigation can return to work.

The company should review whether the employee under investigation is requesting sick leave under appropriate procedures and for a legitimate reason and may consider ways to persuade the employee to cooperate with the investigation. If the employee applies for sick leave following company policy, the company would need to grant such sick leave and suspend the investigation during the sick leave.

Like in the case of grievances (see question 19), the deciding factor will be assessing whether sick leave is related to the investigation or not.

If there is no link between the investigation and the sick leave, then the leave is not relevant from the point of view of the investigation. However, if the sick leave was a result of the investigation (for instance, an employee taking sick leave due to anxiety related to the investigation), then the convenience of pursuing the investigation or of temporarily suspending it should be evaluated to avoid any liability for the company.

The employer is responsible for the employee’s work environment during the investigation. The employer must assess the situation and the impact on the employee’s health and may, depending on the situation, have to postpone certain investigative measures, such as interviewing the employee in question. The investigation may even have to be completed without the employee participating.

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 the absence is anticipated to be brief, the employer may wait until the employee's return before concluding the investigation. If the employee's absence is expected to be prolonged, the investigator may alter the time of meetings or request that the employee submits a witness statement. The key point would be that all necessary measures should be taken to give the employee a chance to participate.

The employee’s participation in the investigation is vital for a fair assessment and to ensure that the employee has been allowed to defend himself or herself against the allegations. As such, every reasonable effort must be made by the employer to adjust the investigation process so that the employee can take part in the investigation. For example, if the employee goes off sick and thus cannot attend the investigation interviews or disciplinary hearings, the investigation should be carried out as much as possible without resorting to the employee in question, by initially exhausting the other available options (such as conducting interviews or disciplinary hearings with other available witnesses). However, if the employee’s absence takes longer than is reasonably expected or the matter at hand must be dealt with urgently, the employer may consider concluding the investigation and determining the next steps based on the information at hand. In such a case, it is recommended to explain in the investigation report the reasons why the employee could not take part in the investigation process (ie, why an interview or disciplinary hearing, etc, could not have been arranged with the employee) along with supporting documentation evidencing the employer’s efforts to involve the employee in the investigation process and the employee’s excuse for not participating interviews or disciplinary hearings.

This is a relatively common occurrence. It would usually be appropriate to suspend the investigation temporarily, to determine how serious the health issue is and when the employee may be fit to return. The investigator should consider what adjustments or allowances can be made to progress the investigation despite the employee’s absence. If their evidence has not yet been gathered, the employee may be invited to provide a written statement instead of attending an investigation meeting, or the meeting could be held remotely or at a neutral location. If none of this is possible, it may be difficult to fully conclude the investigation.  

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. 

Workplace investigations do not require the presence or active cooperation of the employee under investigation. Thus, the investigation may start or continue in the employee’s absence due to illness.

If the employee’s presence is necessary for the conclusion of the investigation, the employer may invite the employee to provide information either by submitting his or her answers to a written questionnaire or attending a virtual meeting. However, the employee may not accede to the employer’s requests and proposals, especially if the employee has an illness. As a result, the employer may not be able to conclude the investigation due to the absence of the involved employee.
