Workplace Investigations

Under the Prevention of Corruption Act 1960 and the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act 1992 (CDSCA), in any civil or criminal proceeding, no witness is obliged to disclose the name or address of any informer, or disclose any information that might lead to his or her discovery concerning offences such as corruption, drug trafficking, and money laundering, save where:

• in any proceeding for the offence, the Court, after a full inquiry into the case, is of the opinion that the informer wilfully made, in his complaint, a material statement that he knew or believed to be false or did not believe to be true; or
• in any other proceeding, the court is of the opinion that justice cannot be fully done between the parties without the discovery of the informer.

In line with the above, employers should therefore keep the informer’s identity confidential upon receiving a complaint relating to corruption, drug trafficking, money laundering, and other serious offences prescribed in the second schedule of the CDSCA.

If an employee complains to his or her superiors about grievances or misconduct in the workplace and is subsequently dismissed, this may constitute an unlawful termination (article 336, Swiss Code of Obligations). However, the prerequisite for this is that the employee behaves in good faith, which is not the case if he or she is (partly) responsible for the grievance.

If unrelated matters that require further investigation are revealed as a result of the investigation, the employer should take the necessary steps to investigate these matters, where relevant, under the employer’s grievance reporting, investigation and disciplinary processes. This should be done separately and independently from the existing investigation. Please note that section 424 of the Criminal Procedure Code imposes a legal duty on any person who is aware that another has committed certain specified offences to "immediately" report the matter to the police, "in the absence of reasonable excuse" not to do so. Failure to comply with this requirement is punishable with imprisonment for up to six months, and/or a fine.

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.
