Workplace Investigations

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).

Employers have obligations to conduct a thorough and unbiased internal investigation and take prompt remedial action to prevent further workplace violations. As such, absent a criminal or regulatory investigation where the investigators ask the employer to pause an internal investigation, employers should be prepared to continue their internal investigation in parallel with the criminal or regulatory investigation while cooperating with police or regulatory investigators.

The police and the regulator can often compel the employer to share certain information gathered from its internal investigation. In some cases, the employer should analyse whether the non-disclosure of information evidencing criminal conduct within the company itself constitutes an independent crime or whether an applicable statute or regulation imposes an independent duty to disclose. Alternatively, the employer should consider whether, even absent an affirmative duty to disclose, disclosure of information gathered during an internal investigation may still benefit the employer.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]

Once fact-finding is complete, the investigator should discuss his or her notes with in-house or outside counsel and prepare a summary of the process, high-level findings, and a proposed resolution at the counsel’s direction. This report should not include subjective commentary and should also avoid including excessive detail, and generally be treated confidentially during and after the investigation. If the report is requested by regulators or the police, the company should discuss with in-house counsel, and preferably also with outside counsel, how to respond to the request and whether any steps need to be taken to protect any applicable legal privilege.
