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.

Litigation privilege may attach to investigation materials if there was a reasonable prospect of litigation at the time of the creation of the materials, and the materials were created for the dominant purpose of a pending or contemplated litigation.

Legal advice privilege may attach to investigation materials if the materials were created to seek or obtain legal advice; or if the materials contain legal advice that is so embedded or has become such an integral part of the materials that the legal advice cannot be redacted from them. If the legal advice is separable from the materials, then only the parts of the materials containing legal advice will be protected by privilege.

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.

If the employee under investigation has already responded to the allegations made against him or her and his or her participation is no longer required at this stage in the investigation, the employer may proceed with the investigation even while the employee is off sick.   

However, if the employee under investigation has not responded to the allegations made against him or her and his or her participation is still required in the investigation, the company may exercise its discretion to pause the investigation until the employee can assist in the investigations.  To prevent an employee from using a medical condition as an excuse to delay or avoid the investigation, the company may require the employee to provide specific medical documentation to address the issue of the employee’s ability to participate in the investigation and to adjust the investigation process accordingly. For instance, instead of scheduling an in-person interview, the company may send a list of written questions for the employee to answer, and may also extend timelines for responding, etc.   

If the employee is unable to return to work for the foreseeable future, the employer may consider reaching a provisional outcome based on the available evidence, which would be subject to change when the employee under investigation can return to work.

The time spent on the internal investigation by the employee should be counted as working time[1]. The general statutory and internal company principles on sick leave apply. Sick leave for which the respective employee is not responsible must generally be compensated (article 324a paragraph 1 and article 324b, Swiss Code of Obligations). During certain periods of sick leave (blocking period), the employer may not ordinarily terminate the employment contract; however, immediate termination for cause remains possible.

The duration of the blocking period depends on the employee's seniority, amounting to 30 days in the employee's first year of service, 90 days in the employee's second to ninth year of service and 180 days thereafter (article 336c paragraph 1 (lit. c), Swiss Code of Obligations).
