Workplace Investigations

Yes, an employer can search the possessions or files of an employee as part of an investigation where the employee’s contract or handbook authorises such a search and there is a reasonable suspicion of wrongdoing.

The basic rule is that the employer may not search private data during internal investigations.

If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

It is not unusual for an employee under investigation to raise a grievance during the investigation. This grievance may be on the same subject matter as the complaint being investigated or may disclose new facts outside the scope of the matter being investigated.

Where the issue discloses new facts, the employer is required to investigate those facts without suspending the investigation. However, where the grievance relates to the same subject matter as the complaint being investigated, the employer may either suspend the investigation to allow the investigation to recognise the grievance and the complaint against the employer or proceed with the investigation while noting that the matter disclosed is being or will be investigated.

In the context of private internal investigations, grievances initially raised by the employee do not usually have an impact on the investigation.

However, if the employer terminates the employment contract due to a justified legal complaint raised by an employee, a court might consider the termination to be abusive and award the employee compensation in an amount to be determined by the court but not exceeding six months’ pay for the employee (article 336 paragraph 1 (lit. b) and article 337c paragraph 3, Swiss Code of Obligations). Furthermore, a termination by the employer may be challenged if it takes place without good cause following a complaint of discrimination by the employee to a superior or the initiation of proceedings before a conciliation board or a court by the employee (article 10, Federal Act on Gender Equality).
