Workplace Investigations

If unrelated matters are revealed because of a workplace investigation, the employer may look into the new matter and then determine whether there are sufficient grounds to proceed with an administrative disciplinary process for the new matter.

There are no regulations in this regard in the Swiss employment law framework. However, in criminal proceedings, the rules regarding accidental findings apply (eg, article 243, Swiss Criminal Procedure Code for searches and examinations or article 278, Swiss Criminal Procedure Code for surveillance of post and telecommunications). In principle, accidental findings are usable, with the caveat of general prohibitions on the use of evidence.

The result of the workplace investigation must be kept private by the employer. These are confidential matters that should not be disclosed to people or entities who did not take part in the investigation. However, if the investigation findings show that a possibly unlawful or criminal activity has taken place, or is about to take place, the employer should share such findings with the authorities.

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]
