Workplace Investigations

Under the Prevention of Corruption Act 1960 and the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act 1992 (CDSCA), in any civil or criminal proceeding, no witness is obliged to disclose the name or address of any informer, or disclose any information that might lead to his or her discovery concerning offences such as corruption, drug trafficking, and money laundering, save where:

• in any proceeding for the offence, the Court, after a full inquiry into the case, is of the opinion that the informer wilfully made, in his complaint, a material statement that he knew or believed to be false or did not believe to be true; or
• in any other proceeding, the court is of the opinion that justice cannot be fully done between the parties without the discovery of the informer.

In line with the above, employers should therefore keep the informer’s identity confidential upon receiving a complaint relating to corruption, drug trafficking, money laundering, and other serious offences prescribed in the second schedule of the CDSCA.

If an employee complains to his or her superiors about grievances or misconduct in the workplace and is subsequently dismissed, this may constitute an unlawful termination (article 336, Swiss Code of Obligations). However, the prerequisite for this is that the employee behaves in good faith, which is not the case if he or she is (partly) responsible for the grievance.

It is up to the employer to determine whether or not to open an investigation after a complaint from a whistleblower. It is very important that the identity of the whistleblower is protected and that the employer also should not reveal the identity of the witness or the source of information, as the sources and witnesses may fear retaliation and feel uncomfortable or hesitant in giving information or raising concerns again.

It would suffice for a summary of the investigation’s findings to be shared with the complainant and the respondent employees.

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.
