Workplace Investigations
Contributing Editors
Workplace investigations are growing in number, size and complexity. Employers are under greater scrutiny as of the importance of ESG rises. Regulated industries such as finance, healthcare and legal face additional hurdles, but public scrutiny of businesses and how they treat their people across the board has never been higher. Conducting a fair and thorough workplace investigation is therefore critical to the optimal operation, governance and legal exposure of every business.
IEL’s Guide to Workplace Investigations examines key issues that organisations need to consider as they initiate, conduct and conclude investigations in 29 major jurisdictions around the world.

Co-workers can be interviewed as part of an investigation where they are witnesses to a complaint. If the employee refuses to attend the interview or is generally not cooperating with the investigation, the reasons for this will need to be considered carefully by the employer. Employers should consider whether there can be any amendments made to the interview process to accommodate the employee. However, an employer can make a reasonable and lawful direction to an employee to attend an interview. If an employee fails to comply with a lawful and reasonable direction, then it may constitute grounds for disciplinary action.
Witnesses who are employees are entitled to the legal protections that ordinarily attach to their employment, including not being bullied, discriminated against, or harassed and having their health and safety protected. Employers should also ensure that witnesses are not victimised as a result of participating in the investigation and that confidentiality is maintained.

An essential part of an internal investigation is the questioning of employees. Their statements contribute significantly to clarifying possible violations. In particular, the legal principles that apply to criminal proceedings, including the right to refuse to testify, do not apply directly to internal investigations.
Employees do not legally have to participate in such interviews. Their duty to cooperate arises indirectly from other legal provisions, in particular from employees’ duties of loyalty and service under labour law.
Austrian law suggests there is a general principle of loyalty, which triggers a “duty to inform” under some circumstances; in principle, the employee and any witnesses are expected to provide information in the context of internal investigations. While the employee is not compelled to incriminate him or herself, he or she also may not withhold work-related information that the employer legitimately wishes to protect, for the sole reason that it might incriminate him or her. The decision as to whether the employee must disclose information depends on a balancing of interests in the specific case.
Investigators and employers must strictly adhere to the permissible limits. This requires compliance with labour law, criminal law and data protection law.

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.

Employees cannot be compelled to act as witnesses. Employers may have trouble enforcing internal policies stating that employees who refuse to participate in investigations will be disciplined (warned, suspended or have their contract terminated for cause), but can terminate their contract without cause.
There are no explicit legal protections for employees acting as witnesses, but it is common best practice to have witnesses’ identities protected to the extent necessary for the investigation, and to protect them from retaliation.

Article 75 of the Civil Procedure Law of the PRC (Amended in 2021) provides, "All entities and individuals that are aware of the circumstances of a case shall have the obligation to testify in court. The persons-in-charge of relevant entities shall support the witnesses to testify in court. "Article 193 of the Criminal Procedure Law of the PRC (Amended in 2018) provides, "Where, after the notification of a people's court, a witness refuses to testify in court without justified reasons, the people's court may compel the witness to appear in court, unless the witness is the spouse, a parent or a child of the defendant."
According to relevant provisions of the Civil Procedure Law of the PRC, only a court has the power to compel a witness to appear in court. Neither the employer nor any other individual may compel any colleague to act as a witness and testify in court. However, the employer may set forth in the employment contract or its internal rules and regulations that the employee shall cooperate with its internal investigation.
As for the legal system for witness protection, PRC's criminal procedure laws stipulate a relatively detailed legal system for witness protection, such as establishing a crime of retaliating against a witness; making public a witness's personal information such as name, address, employer and contact information for the purpose of protecting the personal safety of the witness; using assumed names in the indictments; and so on. However, there are relatively few legal provisions regarding the legal protection of witness in civil procedure, and provisions only regulate the expenses that may be incurred by the witness for testifying in court. For instance, Article 77 of the Civil Procedure Law of the PRC (Amended in 2021) provides, "The necessary expenses incurred by a witness in fulfilling his obligation to testify in court, including transportation, accommodation and meals, as well as the loss of salaries, shall be borne by the losing party. If a party applies for a witness to testify, the costs and expenses shall be advanced by the party; if the people's court notifies a witness to testify without the application by a party, the costs and expenses shall be advanced by the people's court.

There is no legislation on a witness's role in investigations. However, the legislation on occupational safety requires that employees must report any irregularities they observe. Depending on the situation, participating in the investigation may also be part of the person's work duties, role or position, in which case the employer may require the employee to contribute to clarifying the situation. However, there is no formal obligation to act as a witness, and there is no legislation regarding the protection of witnesses. If a witness wishes, they may have, for example, an employee representative as a support person during the hearing.

Co-workers can spontaneously act as witnesses and provide statements to superiors before, during or after the interviews. Co-workers can also be interviewed as witnesses at the investigator’s request, although they are not under any obligation to answer the questions and they cannot be compelled to do so. The investigators have an absolute obligation of discretion during the investigation and cannot reveal any details of the information gathered.
Certain employees may benefit from whistleblower status, which implies that they may be exempt from potential criminal and civil liability relating to their report or testimony and they are protected from any retaliatory measures from the employer. “Facilitators” who helped the whistleblower and the individuals connected with the whistleblower and risk retaliatory measures by testifying as a witness may also benefit from this status, as of 1 September 2022.

Since there is no mandatory law (yet) that provides a framework for workplace investigation interviews, there are also no special protective regulations for employees acting as witnesses.
Employees have a contractual duty to participate in interviews – be it as a suspect or as a witness – as part of workplace investigations. The employee must provide truthful information based on his duty of loyalty if:
- the questions relate to his area of work;
- the employer has an interest worthy of protection in obtaining the information; and
- the requested information does not represent an excessive burden for the employee.
Whether such a burden can be assumed when the employee must make statements by which he may incriminate himself is disputed in German case law and legal literature. The German Federal Labour Court has not yet decided on this question. Since an internal workplace investigation interview is an interview under private law and not under criminal law, there are, in our view, good arguments that the employee must also make a true statement even if he incriminates himself, provided his area of work is concerned. However, some labour courts assume that in these cases such a statement could not be used in criminal proceedings.

Indirectly involved employees may be interviewed as witnesses in the context of the investigation, as the employee has a duty of loyalty towards the employer originating from the employment relationship. However, they cannot be forced to do so (in contrast with criminal procedures). Any harmful act that could be considered retaliation against witnesses in the context of violence or harassment or whistleblowing investigation is prohibited. In addition, the identity of any employees as witnesses is also covered by the principle of confidentiality.

Under Hong Kong law, the employee has an implied duty to obey lawful instructions from his or her employer and to serve the employer with fidelity and good faith during the term of his or her employment. A lawful instruction from an employer may include a reasonable request for the employee to participate and provide information in the workplace investigation. If the employee refuses to comply with such instruction or is obstructive or provides untrue or misleading information, it could constitute a ground for summary dismissal under the EO and at common law.
That said, in general terms, an employer should not compel any employee to testify against a co-worker, particularly if such a co-worker is a senior colleague, as evidence provided under compulsion may not be helpful to the investigation.
Employees who act as witnesses must be treated as per their contractual and statutory rights, including the right against self-incrimination. If the investigation involves allegations of discrimination on the ground of sex, race or disability, the employer should ensure that the witnesses will not be victimised or treated less favourably than other employees.

Yes, in matters pertaining to sexual harassment, the SH Act expressly stipulates that the IC holds the powers of a civil court to summon any person to be examined as a witness. In misconduct cases, the investigating authority can ask employees to appear and testify before it as witnesses and internal policies should have provisions for this. As a result, employees are duty-bound to fairly and honestly participate in any investigative or disciplinary proceedings relating to the workplace, including offering truthful evidence and testimony on matters they may have observed or experienced as an employee of the organisation. While employees don't have any express statutory protections when acting as witnesses, any such policy should be balanced and include necessary safeguards, such as assuring employees that any retaliation against them will not be tolerated and that the details of their participation will only be shared on a need-to-know basis.

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.

In general, employees must cooperate with a workplace investigation (as it is part of their general duty of diligence, as provided under article 2104 of the Italian Civil Code), and this may also include a duty to act as a witness.
In this respect, it must be pointed out that, even if the employee has a contractual duty to provide information requested by the employer, one limit to this principle could be, for example, self-incrimination.
However, caution is necessary during the interviews both with the employee under investigation and with co-workers, to avoid the risk of transforming the interview into what could be considered the de facto start of a disciplinary procedure. In other words, during the interview, the employer should only gather information on certain facts, and not put forward charges against the employee; otherwise, this could prevent or limit the employer’s possibility to take disciplinary action regarding the same facts.
Furthermore, employees who cooperate within the workplace investigation must be protected against any retaliatory action directly or indirectly linked to their testimony (eg, as far as is possible, anonymity should be guaranteed, and disciplinary measures should apply to those who breach measures in place to protect the employee).
Apart from workplace investigations, employees are protected against retaliatory measures of any kind, which are always null and void and subject to appeal.
For a defensive criminal law investigation (see par. 4), the witness can refuse to testify; in this case, the criminal law lawyer may ask the prosecutor to interview the witness.

Interviewing co-workers is often conducted in internal investigations. Company employees are generally required to cooperate with company investigations, especially those who are in a position to instruct and supervise employees, or those who are responsible for maintaining corporate order, since cooperation with an investigation is itself the fulfilment of their duty to the company. Other employees are not compelled to cooperate with such an investigation unless it is deemed necessary and reasonable. No specific legal protection is provided for testifying in an investigation.

There is no statutory regime for employee witnesses in internal (workplace) investigations and, hence, no specific statutory regime for legal protection. However, as part of the idea that employees have to act in line with good employment practices (section 7:611 DCC), employees, who potentially acquired knowledge in a work-related context on the subject matter of an investigation, are typically required vis-à-vis their employer to participate in such internal investigations. The required degree of cooperation will depend on the type and nature of the investigation and the matter that is being investigated. The principle of “good employment practices” in turn requires the employer to be guided by proportionality and subsidiarity considerations: which information is relevant to the investigation and what is the least burdensome means of collecting such information?
This may also impact the degree to which an employer can involve employee witnesses in an investigation. Increased prudence should be observed, among other things, if the relevant employee witnesses may themselves become implicated in the investigation or when the employer envisages sharing certain investigative findings with regulatory or criminal authorities, for instance as part of cooperation arrangements in an ongoing investigation. In such cases, the relevant employee should at least be allowed to retain legal counsel before continuing interview procedures.

The employee’s contract, employee handbook or company policies typically mandate an employee to cooperate and participate in good faith in any lawful internal investigation undertaken by the company, and also protects an employee acting as a witness in an internal investigation. Some of the legal protections available to an employee acting as a witness during workplace investigations are freedom from intimidation, threats or the loss of employment.

In general, an employee may not be forced to act as a witness, but based on the provisions of the Polish Labour Code, an employee must act for the benefit of a working establishment or employer and perform work in line with the instructions of an employer. A lack of cooperation from an employee (eg, refusing to attend a hearing, hiding facts or even false testimony) may constitute a basis for the loss of an employer’s trust in the employee and, as a consequence, may constitute a valid reason for termination (in some specific situations, even without notice).
There is no formal protection for employees who act as witnesses. However, participation in an investigation cannot result in negative consequences (eg, no retaliation is allowed). Also, during an investigation, employees who are bound by professional secrecy are not required to provide information that would imply a breach of such secrecy.

If the employer decides on an internal investigation to assess potential wrongful actions carried out within the company, employees must cooperate. However, employees are entitled to the privilege against self-incrimination established in the Portuguese Criminal Code, according to which individuals are not obliged to self-report.
An employee's refusal to cooperate with an internal investigation may be regarded as a breach of conduct by the employer and, ultimately, may lead to disciplinary sanctions.
Employees who act as witnesses in cases of harassment cannot be sanctioned unless they acted with wilful misconduct, and any sanction applied to an employee who acted as a witness in a harassment procedure will be presumed to be abusive.

Singapore law does not impose any statutory or legal obligation on an employee to act as a witness in the investigation. Accordingly, an employer does not have the power to compel its employees to act as witnesses in an investigation.
Notwithstanding this, an employer may require an employee to assist in investigations pursuant to specific contractual obligations in the employee’s terms of employment (as may be contained in the employment contract, employee handbook or the employer’s internal policies and procedures in dealing with the investigations, etc). Further, a request for an employee to provide evidence of an event that he or she knows of may reasonably be deemed to be a lawful and reasonable directive from an employer.
Consequently, an employee’s refusal to act as a witness may amount to an act of insubordination that may attract disciplinary action by the employer.
Employers requiring employees to act as witnesses in an investigation must ensure that they comply with the expectations and norms set out by the Tripartite Guidelines on Fair Employment Practices and the TAFEP Grievance Handling Handbook.

While there are no laws to compel co-workers to act as witnesses, the company may have internal policies (eg, rules of employment, code of conduct) that require employees to cooperate with company actions such as a workplace investigation. That said, it would be difficult to enforce such policies even if the employee refuses to cooperate (eg, taking disciplinary action against an employee who refuses to act as a witness).
There may be instances when the company is required to provide certain legal protection to employees acting as witnesses in an investigation. For example, if a whistleblower falling under the WPA is required to act as a witness, they would be entitled to legal protections as discussed in question 1. The company may also have internal policies that provide protection to employees acting as witnesses in an investigation.

A company cannot force an employee to actively take part in a workplace investigation or to act as a witness. However, if a co-worker’s decision not to collaborate could be construed as an attempt to conceal evidence of wrongdoing, the company could then enforce disciplinary measures for this reason.
In our experience, employees tend to collaborate during workplace investigations and no retaliatory action can be taken against them for this reason. For example, if an employee provided evidence against his or her direct manager, the manager could not reprimand the employee or take any action that could be construed as such.

In general, yes, employees in Sweden have a far-reaching duty of loyalty toward their employers. This includes, among other things, a duty to truthfully answer an employer’s questions and to inform the employer of events that may be of interest to the employer. An employee’s obligation to assist is, however, more limited when assistance would entail self-incrimination.
A person acting as a witness under an investigation governed by the Swedish Whistleblowing Act will be protected by confidentiality. Personal data and details that could reveal the identity of a witness may not be disclosed without authorisation.

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]

Normally, the work rules prescribe requirements for cooperation with investigations. An employer may instruct co-workers to give statements as witnesses as this would be a fair and legitimate order of the employer, because investigations are conducted to maintain a good working environment.
Witness protection measures in a workplace can vary as no minimum standard has been set and they are generally subject to work rules and regulations. However, some legislation, which may not relate to a workplace investigation conducted by an employer, also protects the witnesses who are helping authorities investigate violations under the relevant acts. For example, the Labor Relation Act B.E. 2518 (1975) prohibits an employer from terminating an employee or conducting any action that may result in the employee being unable to work because of filing a complaint or being a witness for the authorities, or providing information on issues related to labour protection laws to the authorities.
The employer may have a policy of non-retaliation for the protection of witnesses who have given statements and evidence for a workplace investigation.

Co-workers cannot be compelled to act as witnesses in a workplace investigation. Employees also have rights arising from the law that must be respected by the employers and investigators, such as the right to privacy or to remain silent, freedom of expression and communication. These rights must be protected during every step of the workplace investigation process.

Employees may be reluctant to be interviewed or act as witnesses as part of an investigation, perhaps due to fear of reprisals. The investigator should discuss any concerns with the employee and attempt to alleviate any fears.
In general terms, an employer should not compel any employee to provide a witness statement. There may be circumstances in which this could be seen as a reasonable management instruction (and any refusal to comply treated as a disciplinary matter), but these will be rare. Evidence that is compelled is unlikely to be particularly useful to the investigator.
It may be possible to establish an express or implied obligation for senior managers to report on another employee's misconduct – as a feature of either their employment contractual duties, their fiduciary duties or their implied duty of fidelity. However, it is unlikely, in the absence of an express obligation, that a junior employee would be compelled to give evidence against a colleague.
Employees who act as witnesses benefit from their usual employment protections, and must be treated as per their contractual and statutory rights, as well as any policy governing the investigation. If the investigation involves allegations which could involve discrimination, the EA 2010 extends protection from victimisation to “giving evidence or information in connection with proceedings under this Act”. Witnesses should therefore not be subject to any detrimental treatment because they have acted as a witness in this type of investigation. Witnesses may also be entitled to protection as whistleblowers if their evidence amounts to a protected disclosure (see question 9).

Yes. The investigator is empowered to decide which witnesses should be interviewed as a part of the fact-gathering process. In addition to interviewing the complainant, the investigation should include individual interviews with other involved parties, including the subject of the complaint, as well as individuals who may have observed the alleged conduct or may have other relevant knowledge, including supervisors or other employees. Many companies’ code of conduct, employee handbook or similar policy set forth the requirement for current employees to cooperate fully in any investigation by the company or its external advisors and also provide that failure to do so could result in disciplinary action, up to and including termination.
In the absence of contractual protections, employees may have no legal right to refuse to submit to an interview, even if their answers tend to incriminate them. That being said, when acting as a witness in an internal investigation, a current employee is usually afforded similar legal protections as the subject of an investigation, including the right to oppose unreasonable intrusions into his or her privacy and unreasonable workplace searches. For example, certain state laws prohibit an employer from questioning an employee regarding issues that serve no business purpose.

There are no provisions in Vietnamese law that impose any statutory or legal obligation on an employee to act as a witness in an investigation. Hence, an employer does not have the power to compel its employees to act as witnesses in an investigation. However, a request for an employee to provide evidence or give details of an event that he or she knows of may reasonably be deemed to be a lawful and reasonable directive from an employer. Consequently, an employee’s refusal to act as a witness may be tantamount to an act of insubordination, which may lead to disciplinary action by the employer. In any circumstances, if an employee refuses to attend an interview or is generally not cooperating with an investigation, the reasons for this will need to be considered carefully by the employer.
