Workplace Investigations

The identity of the complainant must be kept confidential and cannot be disclosed. There are two exceptions: if the complainant consents to the disclosure; or if the employer is asked for this information by the judicial authorities.

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.

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]

A criminal investigation always takes precedence over other investigations. However, this does not mean that the internal investigation has to stop. It can and should continue, and the report drawn up upon completion of the investigation could be used by the authorities in the criminal investigation. In some cases, especially when privilege does not apply, police or regulatory authorities may request that the employer share such evidence. However, even when privilege does apply, there is no certainty that the evidence would not have to be communicated to certain authorities.

Some administrative authorities often challenge the application of legal privilege or try to reduce its scope. For example, the French financial markets authority (AMF) regularly puts forward its view of legal privilege, according to which an email where a lawyer is only copied (and is not one of the main recipients) in from one of their clients is not confidential and can therefore be disclosed in proceedings. However, if the AMF investigators impose disclosure of privileged documents, this should result in the annulment of the investigation procedure. By way of exception, legal privilege cannot be invoked against certain other authorities, such as the URSSAF (authority in charge of collecting social security contributions) or the DGCCRF (directorate-general for competition, consumer protection and anti-fraud investigations). Where legal privilege is enforceable, the judge must first determine whether the documents constitute correspondence relating to defence rights and, second, must cancel the seizure of documents that they find to be covered by legal privilege due to the principle of professional secrecy of relations between a lawyer and their client and the rights of defence.

Often the tests or standards applied by external agencies (such as the police or regulators) in their investigations vary significantly in comparison to those that apply for internal investigations that are focused on potential disciplinary action against an accused employee. For example, the standard of proof required for taking an internal disciplinary measure is one of a preponderance of probability and does not require the employer to establish guilt beyond a reasonable doubt, which is the standard applied in criminal proceedings. Depending on the circumstances, conducting or continuing an internal investigation can also place the organisation in a better position to collaborate with external agencies such as the police or a regulator in their investigations, and be better prepared to share information that such agencies may request. It may also help demonstrate that the organisation does not tolerate potential violations of law or its policies and that it proactively investigates and addresses such issues. This may also help in protecting innocent members of management from liability from external agencies. To that extent, a parallel criminal or regulatory investigation may not normally be a reason for the organisation to suspend its internal investigation.

In the context of sexual harassment claims, the complainant has the right to file a police complaint against the alleged harasser (and the organisation must support  her in doing so). However, a parallel police investigation would not take away the organisation's responsibility to address the grievances through its IC, which would be expected to complete its proceedings within 90 days.  

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).
