Workplace Investigations

According to section 6(1) of the DSG, employees who have access to personal data in the course of their professional activities must maintain data confidentiality and continue to do so even after termination of their employment.

Non-disclosure agreements can generally be used to achieve this but are subject to certain restrictions. They may not be used to conceal criminal activity, violate the privacy rights of individuals, circumvent legal disclosure obligations, prevent the exercise of legal rights or contain clauses that violate existing laws, in particular data protection regulations.

In addition to the above-mentioned statutory confidentiality obligations, separate non-disclosure agreements can be signed. In an internal investigation, the employee should be expressly instructed to maintain confidentiality.

Private investigations differ from criminal or regulatory investigations. Nevertheless, even for internal investigations, it is advisable to collect evidence in a way that can be admitted in court, as it may have to be presented to the authorities during the investigation process. Generally, any evidence obtained in the course of an internal investigation may be admitted in subsequent administrative or judicial proceedings.

If the evidence is not voluntarily surrendered, seizure or confiscation is possible. Since official proceedings are often lengthy, suspension is not always recommended.

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).
