Workplace Investigations

An investigation can be initiated in several ways. It is usually as a result of whistleblowing or a report on work environment deficiencies, or through other channels (eg, HR, the police, media coverage).

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]

According to the GDPR, personal data can only be processed for specified, explicit and legitimate purposes and may not be further processed in a manner that is incompatible with those purposes. This imposes restrictions on the use of material from previous investigations in new investigations when the material was collected for other purposes. It is, therefore, necessary to ensure whether the new matter relates to the investigation and falls within the purpose of the investigation. If the new matter is unrelated to the investigation and does not fall within the purpose of the investigation, the identified information may not be processed under the GDPR.

Except for what is stated above, no regulation limits how the employer can use information regarding unrelated matters. Unrelated matters may be a myriad of different things, and could in some instances just be discarded, while in other situations the information may invoke a responsibility to act for the employer (eg, if the unrelated matters concern work environment issues or other severe misconduct by an employee who is not the target of the investigation). Furthermore, the employer may always use any revealed information (unrelated or not) as evidence in a court of law, since the principle of free examination of evidence applies.

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.
