Workplace Investigations

As part of an investigation, an employer may search objects or files that are the company’s property (eg, electronic devices given by the employer for business purposes and emails or messages stored on the company’s server) without prior notice and the employee’s consent is not needed. The employer, however, has no right to search an employee’s possessions (eg, a private smartphone) without the employee’s consent.

To avoid arguments as to who a particular object belongs to, employers may specify in internal policies what is to be regarded as a corporate asset and could be subject to a search in a workplace investigation.

Concerning an employee’s possessions, even if he or she consents to a search, it is good practice for the employer to conduct the search in the presence of the employee or an independent third party who can act as a witness to the search. If the employer suspects that a criminal offence has been committed and that a search of the employee’s possessions would reveal evidence, the employer should consider reporting its suspicion to the police, as they have wider legal powers to search.[1]

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]

If unrelated matters are revealed during the investigation, the employer should consider whether an investigation is needed. If yes, the employer should decide whether it is appropriate to incorporate the new matters into the scope of the existing investigation by expanding the terms of reference. However, it may not be appropriate to do so if different individuals are concerned or such inclusion would unduly complicate or delay the progress of the existing investigation. If that is the case, the employer should commence a separate investigation.

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.
