Workplace Investigations

The employer is responsible for the work environment and must ensure that employees are not at risk of mental (or physical) illness due to an investigation. If an employee, in connection with an investigation, requires support or if risk of ill health is otherwise anticipated, the employer is obliged to assess the situation and provide said employee with sufficient support (eg, counselling or work adjustments).

The employer does not generally need to provide specific support for employees that are subject to an internal investigation. The employer may, however, allow concerned employees to be accompanied by a trusted third party such as family members or friends.[1] These third parties will need to sign separate non-disclosure agreements before being involved in the internal investigation.

In addition, a company may appoint a so-called lawyer of confidence who has been approved by the employer and is thus subject to professional secrecy. This lawyer will not be involved in the internal investigation but may look after the concerned employees and give them confidential advice as well as inform them about their rights and obligations arising from the employment relationship.[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.
