Workplace Investigations

The circumstances in which an employer commences a workplace investigation may vary. However, it is common that an employer will consider it necessary to commence a workplace investigation upon receipt of a complaint concerning a fellow employee. Sometimes, the complaint may be made anonymously. If the employer considers there to be substance in the complaint, it may commence an investigation to find out the truth of the matter, resolve the complaint and, if necessary, improve its systems and controls to prevent the reoccurrence of any misconduct.

A workplace investigation may be warranted if the employer receives an enquiry from a regulator concerning its affairs or an employee’s conduct. The investigation findings could enable the employer to respond to the regulator (which could be a mandatory obligation) and at the same time assess its risk exposure.

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[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.
