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.

Employers will generally take steps to treat complaints sensitively and confidentially. However, because of the obligations employers have, confidentiality cannot be guaranteed as part of the investigation and the complainant, respondent and witnesses should be made aware of this.
Understandably, the complainant or witnesses may wish to remain anonymous. However, because the details of the allegations need to be put to the respondent so that they can provide an informed response or explanation, the source of the information will often need to be disclosed.
Employers can take steps to “ringfence” the investigation by asking employees to sign a confidentiality agreement. This will protect the interests of the participants of the investigation and uphold the integrity of the investigation.

When dealing with reports and persons covered by the HSchG, the provisions on identity protection must be followed. In all internal investigations, only authorised persons should receive information.

If the complainant made use of an internal whistleblowing procedure, confidentiality regarding the identity of a reporter is mandatory. Also, in other cases and for other involved persons (witnesses), it is recommended to keep their identity confidential to prevent the risk of intimidation or other negative consequences.
In complaints due to sexual harassment, violence or bullying at work, if the prevention adviser heard or took written statements from persons that were considered useful for the evaluation, these persons may remain anonymous.
The employee must, nevertheless, receive sufficient information to be able to offer a defence concerning the facts of which he or she is accused.

At the level of criminal procedure in PRC, only the Criminal Procedure Law of PRC provides that pseudonyms may be used in the indictment as a substitute for the disclosure of a witness's personal information, such as name, address, employer and contact information, to protect the personal safety of the witness. However, there are no relevant provisions on whether the identity of the complainant, the witness in civil litigation and the provider of information shall be kept confidential during an investigation.
During the course of an investigation, in order to protect the privacy of relevant personnel and avoid the risk of infringement, the employer usually keeps the identity of the complainant or the provider of investigation information confidential. However, at the civil litigation stage, the witness is unavoidably required to testify in court, and must truthfully identify himself/herself to the court.

There is no general obligation on the part of the employer to disclose to the employee concerned the identity of the complainant, witnesses or other sources of information during the workplace investigation.
However, as described in question 11, the employee must be sufficiently informed of the allegations before a termination based on suspicion of wrongdoing is issued. This may also require disclosing the complainant's or witnesses' identity or other sources of information. In addition, the employer would have the burden of proof in the context of a legal dispute (eg, termination protection proceedings or proceedings about the legality of certain investigation measures) and may have to name witnesses and disclose sources of information.

According to express provisions of L.4990/2020, in principle personal data and any other information that may lead directly or indirectly to the identification of the complainant must not be disclosed to anyone other than the investigating individuals unless the complainant gives consent[4] and that is why pseudonyms should be used. The witnesses and third persons that aid the complainant are deemed as “mediators” by the Law and their contribution to the procedure should be confidential[5].
L.4808/2021 does not indicate when such disclosures are permitted; however, it is obvious that this is a matter of cost-benefit analysis where the public interest and the fundamental rights of the involved persons should be considered in a balanced way to ensure the best results. From a data protection perspective, it could be argued that the person under investigation’s right to know the identity of the complainant, witnesses or sources of information should be limited to protect the rights of these persons.

Subject to any internal policies and terms of the employment contract, an employer would have discretion as to whether the identity of the complainant, witnesses or sources of information for the investigation should be kept confidential. In general, the employer should consider how the confidential treatment or its absence would affect the conduct and outcome of the investigation. The disclosure of the identity of the complainant in some cases may be necessary for the employee under investigation to respond in a meaningful way. On the other hand, both the complainant and witnesses may be more forthcoming in providing information if he or she is assured that his or her identity will not be made known to the person under investigation (especially if the latter is senior management personnel). A balance should be struck between the interests of the complainant or witnesses in maintaining confidentiality and the need for the employee under investigation to make a proper response to the allegations made. In any case, the employer should follow its whistleblowing policy if there is one (as discussed in question 9), and take into account practical and statutory considerations relating to confidentiality (as discussed in question 10).

The response and approach to this would be very fact-specific.
Under the SH Act, an individual cannot file an anonymous complaint and, therefore, the name of the complainant cannot be kept confidential. The same would go for details of witnesses, if any.
For other types of misconduct, the name of the complainant could potentially be kept confidential, depending on the nature of the allegations. For example, if an individual observes another colleague or employee committing inappropriate conduct (such as fraud or bribery) and reports this, the name of the complainant may not necessarily have to be disclosed to the accused employee, especially where the company is independently able to gather evidence substantiating the allegations. The names of witnesses generally cannot be kept confidential, since doing so may prove prejudicial to the accused employee. Further, as part of the disciplinary inquiry process, the accused has the right to cross-examine witnesses.
Notwithstanding the above, the approach to this issue should be assessed on a case-by-case basis by looking at the underlying sensitivities and risks involved. Courts have, in limited circumstances, permitted non-disclosure of the names of witnesses or complainants.

Yes, in principle the identity of the complainant, witnesses or sources of information for the investigation can be kept confidential.
On the other hand, if the employer – after having concluded the investigation – brings disciplinary action against the employee, the employer must send a letter to the employee in which the facts are described in detail, objectively and in a precise way, identifying when and where they have taken place, to allow a proper defence for the employee.
Even at this stage, however, the employer has no obligation to provide the employee with the evidence underlying the facts ascribed to him (ie, the employer has no obligation to specify the identity of the individuals through which they gained knowledge of the facts reported in the disciplinary letter).
However, if the employee subsequently challenges the disciplinary sanction before a judge, the employer bears the burden of proof, which may mean having to call the individuals interviewed within the internal investigation to stand as witnesses in court.
Moreover, in case of whistleblowing reports falling within the scope of the WB Decree, the employer is requested to generally keep the whistleblower’s identity confidential (according to art. 12 of the WB Decree). More specifically: (i) if the disciplinary charges are grounded on investigations which are different and additional to the whistleblowing report (although arising as a consequence of the report), the whistleblower’s identity may not be disclosed; (ii) if the disciplinary charges are grounded, in whole or in part, on the whistleblowing report, and knowing the identity of the whistleblower is indispensable for the defendant, such report may be used for the purpose of the disciplinary proceeding only if the whistleblower gives consent to his/her identity being revealed.

For whistleblowing investigations, whistleblower protection is required (see question 9).
Witnesses and other sources of information are not protected by the Whistleblower Protection Act.
In addition, as a response to a report of harassment, the Ministry of Health, Labour and Welfare guidelines require that necessary measures be taken to protect the privacy of the reporter, the offender, and others, and that these measures be announced to the company.

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

An employee served a notice of accusation is entitled to assess all information that was gathered within the scope of the investigation and disciplinary procedure (notably the identity of the complainant, witnesses heard, other sources of information, etc), otherwise his right of defence may be jeopardised.
Where a preliminary investigation does not lead to an accusation against the employee, no disclosure has to be made by the employer.

As in question 10, the identity of the complainant or other employees involved in the investigation may be kept confidential and companies do not have to share their identity with investigated employees. Anonymous complaints are expressly allowed under Spanish law (see question 9).
Companies may have to produce this information and share it with the investigated employees if it is necessary to allow them to defend themselves from disciplinary measures taken against them. Similarly, in the context of litigation, an employee or plaintiff could request a Labour Court to order the company to disclose the details of the investigation.

If the Swedish Whistleblowing Act applies, their identity must be kept confidential under the duty of confidentiality. If the Swedish Whistleblowing Act does not apply, their identity can to a large extent be kept confidential.
It can also be noted that a workplace investigation carried out in the public sector will often (eventually) become an official document, which means that the document can be requested by the public. There are, however, provisions on secrecy that may restrict the right to gain access to official documents. These provisions are found in the Public Access to Information and Secrecy Act (2009:400).

As mentioned under Question 10, the employer’s duty of care (article 328, Swiss Code of Obligations) also entails the employer’s duty to respect and protect the personality (including confidentiality and privacy) and integrity of employees (article 328 paragraph 1, Swiss Code of Obligations) and to take appropriate measures to protect them.
However, in combination with the right to be heard and the right to be informed regarding an investigation, the accused also has the right that incriminating evidence is presented to them throughout the investigation and that they can comment on it. For instance, this right includes disclosure of the persons accusing them and their concrete statements. Anonymisation or redaction of such statements is permissible if the interests of the persons incriminating the accused or the interests of the employer override the accused’ interests to be presented with the relevant documents or statements (see question 11; see also article 9 paragraphs 1 and 4, Swiss Federal Act on Data Protection). However, a careful assessment of interests is required, and these must be limited to what is necessary. In principle, a person accusing another person must take responsibility for their information and accept criticism from the person implicated by the information provided.[1]

It is generally possible to keep the identity of the complainant, witnesses, or information sources confidential. There is no mandatory rule to disclose the identity of a complainant, witnesses, or sources of information. If the complainant, witnesses, or sources of information for the investigation know that their identities would not be disclosed, they will be more confident in cooperating with and supporting the investigations.

It is possible to keep such information confidential. If this is the case, the investigation team should conduct the interview outside the workplace of the company. This is actually good practice applicable to all internal investigations, unless there is a particular reason that requires the meetings to be held at the company.

Only in exceptional circumstances, such as where there is a genuine risk of retaliation. Anonymising a complaint puts the employee under investigation at a significant disadvantage, as they may be unable to properly challenge the evidence against them. It can also impair the effectiveness of the investigation. Employers should, therefore, not provide any guarantees of confidentiality to complainants or to employees who are to act as witnesses. That said, employers should think carefully about any necessary disclosure of names or facts. This can be particularly relevant where the witness is subordinate to the employee being investigated.

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