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.

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.

Confidentiality protects the interests of the persons involved in the investigation as well as the integrity of the investigation. Before providing information as part of the investigation, employers should direct the complainant, respondent or witnesses to sign confidentiality agreements. This agreement should direct the person to refrain from discussing the investigation or matters that are the subject of the investigation with any person other than the investigator.
It is also best practice for participants in the investigation to be directed not to victimise (threaten or subject to any detriment) any persons who are witnesses to or are otherwise involved in the investigation.
After an investigation, employers should write to the complainant, respondent and any witnesses reminding them of their ongoing confidentiality obligations.

If the report and the whistleblower fall within the scope of the Whistleblowing Directive, his or her identity must be protected. From a data protection perspective, the principles of the DSG must be observed to protect the legitimate confidentiality of the individuals concerned.
Furthermore, the employer should ensure that information is only disclosed to trustworthy persons to avoid pre-judgements.

A workplace investigation is often a sensitive matter that requires necessary confidentiality to find out the truth discreetly and objectively. Nevertheless, there is often pressure from employees, trade unions or even the media and general public to be transparent and communicate about the case. From a legal perspective, it is not recommended to communicate openly about an ongoing investigation, as this can jeopardise the investigation or the possibility of taking disciplinary measures.
Whistleblower investigations will be bound by a strict duty of confidentiality regarding anything that could reveal the identity of the reporter.
In complaints due to sexual harassment, violence or bullying at work, the prevention adviser is bound by professional secrecy. Consequently, he or she may not disclose to third parties any information about individuals that have come to his or her knowledge in the performance of his or her duties. However, he or she still has the freedom to inform the people concerned to carry out his or her tasks in the procedure.

Law 14.457/2022 states that companies must guarantee the anonymity of accusers. As a result, it is best practice that companies allow for anonymous submissions, or allow accusers to voluntarily disclose their identity while acknowledging that they agree that it will be kept confidential to the extent required by the investigation.
Also, companies should have internal rules stating that all parties involved in an investigation (accusing party, accused party, witnesses, investigators, and any other person that has any contact with the investigation) must keep the existence of the investigation and of the events related to the investigation confidential to the extent required by the investigation, and discipline any individuals that violate this.

Although there are no specific laws or regulations regulating the extent of confidentiality obligation employers or the investigators shall comply with, in practice, the confidentiality obligation of both parties usually originates from the confidentiality agreement between the employee and the employer, as well as general provisions on protection of personal information and right of privacy, etc.
In this regard, it is advisable to require the relevant personnel responsible for handling the suspension for investigation to sign a confidentiality agreement or a letter of commitment, and require them to pay attention to the protection of the personal information and privacy of the complainant and other relevant personnel, for the purpose of avoiding extra losses caused by the occurrence of disputes relating to right of reputation, right of privacy and personal information leakage during the investigation.

Concerning a workplace investigation, there is no specific legislation in force at the moment regarding confidentiality obligations. All normal legal confidentiality obligations (eg, obligations outlined in the Trade Secrets Act (595/2018)), and if using an external investigator, the confidentiality obligations outlined in the agreement between the employer and the external investigator, apply. Attorneys-at-law always have strict confidentiality obligations as per the Advocates Act (496/1958).

Interviewers, investigators, interviewees or any others involved in the investigation are often bound by a reinforced confidentiality obligation, particularly when the internal investigation is triggered by a whistleblower alert. In addition, every person that comes to know of the investigation, facts or people involved is bound by an obligation of discretion. Furthermore, investigators should specifically be trained for interviews and be reminded of their obligations relating to the investigation.
The investigators will need to determine the order of the tasks to be carried out in the investigation, as this will have a significant impact on confidentiality management. Should they start with the hearings or a review of documents? The answer may depend on the subject matter of the investigation. It is advisable to first review the documentation before organising interviews, particularly to avoid the destruction of certain documents by employees acting in bad faith or by those wishing to erase the traces of alleged wrongdoing. Sometimes, however, it is possible to start with the interviews, especially in the case of harassment, as there may be no documents to review. If the decision is taken to conduct the documentation review after the interviews, it could be useful to ask the employees involved to sign a document stating that they must preserve and retain documents, meaning that if they delete or destroy documents, they would be acting against the company and in breach of the law.

Depending on the subject of the investigation and the severity and significance of the suspected violation, employees who are involved in the workplace investigation may already have to maintain confidentiality based on their contractual duties. The prerequisite for this is that the employer has a legitimate interest in maintaining confidentiality. Criminal acts are not subject to confidentiality, but there is also no general obligation for the employee to report or disclose a criminal act to the authorities or the public prosecutor. However, reporting to the competent authorities may be required in certain cases (see question 25).
Lawyers are bound by professional confidentiality and are generally not allowed to provide information about any information they receive from their clients. An exception exists, for example, if the lawyer must provide information to defend himself in court proceedings. There is also no absolute protection against the seizure of documents at an attorney’s office (see question 14).

Confidentiality applies as a general principle in disciplinary investigations.
Moreover, L. 4990/2022, which transposed EU Directive 2019/1937 into Greek Law, regulates the issue of confidentiality during investigations that start based on an internal report. The managers conducting the investigation must respect and abide by the rules of confidentiality regarding the information they have become aware of when exercising their duties[1]. They must also protect the complainant’s and any third party’s (referred to in the report) confidentiality by preventing unauthorised persons from accessing the report[2].
Finally, L. 4808/2021 provides that employers must create a procedure that should be communicated to employees regarding all the necessary steps of an investigation following a complaint. Throughout the whole process, the employer, managers and the employer’s representatives responsible for the investigation must respect and abide by the rules of confidentiality in a manner that safeguards the dignity and personal data of the complainant and the person under investigation[3].

Workplace investigations should usually be conducted on a confidential basis to preserve the integrity of the investigation, avoid cross-contamination of evidence and maintain the confidentiality of the employee under investigation. This means that those involved in the investigation (ie, the subject employee and any material witnesses) should be made aware of the fact and substance of the investigation on a need-to-know basis.
While the extent of the confidentiality obligations are usually governed by the employer’s internal policies and the employment contract, there are circumstances where the employer has a statutory duty to keep information unearthed in the investigation confidential. For instance, if it is found that certain property represents proceeds of an indictable offence[1] or drug trafficking[2], or is terrorist property[3], the employer should report its knowledge or suspicion to the Joint Financial Intelligence Unit (JFIU) as soon as is reasonably practicable and avoid disclosure to any other person as such disclosure may constitute “tipping off”. Another example is if a workplace investigation is commenced in response to a regulatory enquiry, the employer may be bound by a statutory secrecy obligation and may not be at liberty to disclose anything about the regulatory enquiry to anyone including those who are subject to the workplace investigation. For example, section 378 of the Securities and Futures Ordinance (SFO) imposes such a secrecy obligation on anyone who is under investigation or assists the Securities and Futures Commission (SFC) in an investigation.[4]

Indian labour statutes do not contain any specific confidentiality obligations concerning investigations. However, in practice, the records of investigative or disciplinary proceedings should be kept confidential and shared only on a need-to-know basis to ensure that the parties do not suffer prejudice. The internal policies should also include provisions on confidentiality.
The SH Act, however, provides that certain information must not be published or made known to the public, press and media such as:
- the contents of the SH complaint;
- the identity and addresses of the complainant, accused and witnesses;
- any information on the conciliation and inquiry process;
- the recommendations of the IC; and
- action to be taken by the employer.
The SH Act permits the dissemination of information regarding remedies extended to any victim without disclosing the name, address or identity of the victim or witnesses. The SH Act also outlines punishments for violating confidentiality obligations.

This will depend on the nature of the investigation but, generally, investigations should be conducted on a confidential basis. All who participate in the investigation should be informed and reminded that confidentiality is a paramount consideration taken very seriously. However, it should be borne in mind that confidentiality cannot be guaranteed by an employer as the respondent in an investigation is entitled to know who has made complaints against them. Furthermore, the respondent is entitled to cross-examine the complainant and any witnesses, although in practice this right is rarely invoked strictly and is facilitated by the investigator, with questions from the respondent being put to the complainant and other witnesses.
On occasion, a breach of confidentiality may warrant disciplinary action, but this will depend on the circumstances. Exceptions to the requirement to keep matters confidential will of course apply where employees seek support and advice from others such as companions, trade union representatives or legal advisors. It may also not be possible to maintain confidentiality where regulators or the authorities are informed of the investigation.
Also, confidentiality may not be maintained if it is in the interests of the employer to communicate the complaint and any subsequent investigation, for example on a health and safety basis.

From an employment law perspective, confidentiality obligations may be seen from two different points of view:
- as a general duty of the employee related to the employment relationship, according to article 2105 of the Italian Civil Code, a “loyalty obligation”, which includes confidentiality obligations. On top of these, there are usually further confidentiality clauses in individual employment contracts; and
- as a general duty (linked to the outcome of the investigation) of the employer to keep confidential the identity of the employee who cooperates during the investigation (as whistleblower or a witness) to protect him or her.
In defensive criminal law investigations, the witness can’t reveal questions or answers given in his or her interview to a third party.
With regards to the confidentiality applicable to the whistleblower, see above under question 9 and below under question 12.

Other than the above, there is no specific legal obligation to maintain confidentiality for persons in charge of investigations, etc. However, if the information falls under the category of confidential information obtained by employees in the course of their work, compliance is required as an obligation attached to a labour contract, and many employment regulations stipulate a duty to keep information obtained in the course of work confidential.

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

Workplace investigations should be kept strictly confidential to protect the parties involved in the investigation from victimisation. Some of the confidential obligations that apply during investigations are the identities of the parties involved in the process (whether as a complainant, respondent or witnesses), the confidentiality of reports, recordings and other documents generated or discovered during the investigation, as well as attorney-client privilege between the employee and his or her attorney, provided that such privilege is within the bounds of the law.

The law does not cover this issue, apart from whistleblower regulations, as it should be regulated by the employer in their internal rules. The employer should ensure all participants of the investigation keep information related to it secret, as long as is necessary for the investigation (or even longer, if required by law concerning personal data or other specially protected information). Reputation, personal data and the personal rights of other people cannot be breached during the proceedings and this should be protected.
Moreover, according to the Draft Law – a whistleblower’s personal data should be kept confidential. It can only be disclosed if law enforcement authorities require it. Also, confidentiality should be guaranteed for the subject and other interested persons.

The Portuguese Labour Code does not specifically provide for any confidentiality obligations concerning disciplinary procedures. On the contrary, it states that the employee should have access to any information included in the disciplinary procedure. Otherwise, the employee’s defence rights could be jeopardised, which would make the disciplinary procedure (and possible disciplinary sanctions) null and void.
As for the witnesses, even though there is no specific provision on confidentiality, employees are generally bound by a duty of loyalty vis-a-vis the employer, which includes not disclosing information that should be kept reserved,
However, in the cases of whistleblowing, it is mandatory to ensure the confidentiality of the complainant, as per question 9.

The existence and scope of any confidentiality obligations would generally depend on the specific terms of the employment contract, employee handbook or the employer’s internal policies and procedures in dealing with the investigations.
In the context of investigations into workplace harassment issues, the Tripartite Advisory on Managing Workplace Harassment issued by the MOM provides that the identities of the alleged harasser, affected persons and the informant should be protected unless the employer assesses that disclosure is necessary for safety reasons.
This may change with the enactment of the Workplace Fairness Legislation referred to in question 1. The Tripartite Committee on Workplace Fairness recommended, among other things, that employers should protect the confidentiality of the identity of persons who report workplace discrimination and harassment, where possible. As such, it is expected that the upcoming Workplace Fairness Legislation may impose certain confidentiality obligations on an employer during an investigation.

It is general practice in Korea for a company to require interviewees to maintain confidentiality concerning a workplace investigation and instruct them that they are not permitted to discuss the matter under investigation with other employees, etc. If an employee violates this instruction, it may be possible for the company to take disciplinary action against them under the company’s rules.
Further, the company or its employees who have engaged in an investigation for sexual harassment or workplace harassment in the workplace are obliged to maintain the confidentiality of the investigation. Failure to comply with such requirements may lead to an administrative fine from the Ministry of Employment and Labour for the company or its registered representative.
There may be some exceptions to the confidentiality obligation, such as when an employee is required by government authorities to provide relevant information in a parallel investigation.

Companies and employees are not bound by any statutory confidentiality obligation in the context of workplace investigations. However, if a company’s enquiry has the potential to examine employees’ private affairs, then the company must ensure the confidentiality of the investigation.
This confidentiality obligation would not arise from the investigation itself, but from the company’s obligation to safeguard its employees’ rights.

If the Swedish Whistleblowing Act applies, the persons or entities handling the investigation have a duty of confidentiality and may not, without permission, disclose any information that could reveal the identity of the reporting person, any person subject to the report or any other person mentioned in the report or during the investigation of the report. Access to personal data is limited to designated competent entities or persons. Investigative material including personal data may not be shared with other persons or entities during the investigation. Once the investigation has reached actionable conclusions, investigative material may be shared with other persons or entities, such as HR or the police, provided that such sharing is necessary to take action on the outcome of the investigation. Investigative material may also be shared if it is necessary for the use of reports as evidence in legal proceedings or under the law or other regulations.
If the Swedish Whistleblowing Act does not apply, there are no particular confidentiality obligations for employers. Yet, an employer needs to consider what information is suitable to share during an investigation, how this is done and to whom it is shared. An employer must also respect employees’ privacy in line with what is generally considered good practice in the labour market. This means that an employer should be careful as to what sensitive and personal information is shared during an investigation. Furthermore, the spreading of damaging information (even if true) about an employee to a wider group may be a criminal offence under the Swedish Criminal Code.

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]
In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]
In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]

Unless the investigation is handled by a qualified professional (eg, attorney or auditor) where certain privileges apply, confidentiality obligations are generally subject to the contractual arrangement between the parties involved in the investigation. The employers need to inform any persons, including the investigators, to respect confidentiality obligations because a leak of the information gathered from the investigations could cause damage to relevant parties.

As a general practice, workplace investigations need to be kept confidential for the integrity of the process. In some cases, employees can specifically request their identity or involvement be kept confidential. In such cases, additional measures need to be taken to protect confidentiality. In any case, obligations and rights arising from the DPL and Labour Law must be respected and complied with by the employer and the investigation team.

Workplace investigations should usually be conducted on a confidential basis, so that only those involved in the investigation are aware of its existence and subject matter. The need to maintain confidentiality about both the fact of the investigation, and any content discussed with an investigator, should be emphasised to all those involved. It may also be necessary to explain that a breach of confidentiality could be viewed as a disciplinary matter. Appropriate exceptions must, however, be made to allow employees to speak to any relevant employee or trade union representative, legal adviser and potentially the police or other regulators. Confidentiality provisions cannot override the rights of workers to make protected disclosures (see question 9).
In some situations, such as those involving a wide-ranging investigation into the organisation’s working practices and culture, it may be more appropriate to investigate a more “open” basis, and inform employees and other stakeholders.

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