Workplace Investigations

The employer’s internal policy can indicate that investigation materials must be kept confidential.

Attorney-client privilege will apply to all communication and investigative material between a client and its law firm. Attorney-client privilege is, however, not without limitations. Regarding investigations into alleged employee misconduct, a law firm may have to report suspected money laundering to the authorities and under certain circumstances disclose information to the financial police.

Written material covered by attorney-client privilege generally may not be seized.

As outlined above, all employees generally have the right to know whether and what personal data is being or has been processed about them (article 8 paragraph 1, Swiss Federal Act on Data Protection; article 328b, Swiss Code of Obligations).

The employer may refuse, restrict or postpone the disclosure or inspection of internal investigation documents if a legal statute so provides, if such action is necessary because of overriding third-party interests (article 9 paragraph 1, Swiss Federal Act on Data Protection) or if the request for information is manifestly unfounded or malicious. Furthermore, a restriction is possible if overriding the self-interests of the responsible company requires such a measure and it also does not disclose the personal data to third parties. The employer or responsible party must justify its decision (article 9 paragraph 5, Swiss Federal Act on Data Protection).[1]

The scope of the disclosure of information must, therefore, be determined by carefully weighing the interests of all parties involved in the internal investigation.

The result of the workplace investigation must be kept private by the employer. These are confidential matters that should not be disclosed to people or entities who did not take part in the investigation. However, if the investigation findings show that a possibly unlawful or criminal activity has taken place, or is about to take place, the employer should share such findings with the authorities.

Findings may have to be handed over to the police or the regulator – there is no separate legal protection for material in employer investigations related to authorities. If the investigation has been carried out by a law firm, see question 14 on attorney-client privilege.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]
