Workplace Investigations

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.

If unrelated matters are revealed during the investigation, the employer should consider whether an investigation is needed. If necessary, 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, such action may not be appropriate if different individuals are involved or the inclusion of a new unrelated matter would unduly complicate or delay the progress of the existing investigation. If that is the case, the employer should investigate that matter separately.

Also, as detailed in article 19 of the 2015 Criminal Code of Vietnam, there is a legal duty on any person who is aware that a certain violation is being committed or has been committed to report it to the police unless otherwise provided for under law. Failure to comply with this requirement may lead to criminal liability for the offender.

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]

There is no obligation to share the investigation report or the findings unless the employer and employee agree to do so.

However, under Decree No. 13/2023/ND-CP on personal data protection, the contents of the investigation report or findings related to the employee are likely to constitute the personal data of the employee under investigation. In that case, the employee may have a right under the said Decree to obtain copies of such documents by making a statutory data access request after the workplace investigation is completed. Where the employer is required to provide such documents to the employee under Decree No. 13/2023/ND-CP but the requested documents also contain the personal data of any other third parties (such as the employee’s co-workers who participated in the interview during the investigation), the employer should first redact or erase such data before providing the requested documents, unless the relevant third parties have consented to the disclosure of their personal data.
