Workplace Investigations

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.

The employer should first identify which individuals may have protection as whistleblowers. This could be a current or former employee who raises the initial complaint, a co-worker who gives evidence as part of the investigation, or the accused employee.

In each case, consider whether a “protected disclosure” has been made (under Part IVA ERA 1996). This requires analysis of the subject matter of the disclosure, how it is made, and a reasonable belief that it is made in the public interest.

Employers must then ensure there is no detrimental treatment or dismissal of any worker on the grounds of their protected disclosure. Although the causation test for these purposes is not straightforward, as a general rule if the protected disclosure has a “material influence” on the decision to discipline or dismiss, there may be liability. Individual managers may be personally liable alongside the employer. Compensation for whistleblowing cases is uncapped, meaning businesses and individuals can face significant financial and reputational exposure.

What this means in practical terms is that the employer should promote a “speak-up” culture and, where protected disclosures are made, ensure they are handled by a team who are properly trained in how to do so.

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]

Primarily, the investigation findings are disclosed to the employer and the employee under investigation. In scenarios involving allegations of a breach of regulatory duty or criminal law, the authorities may have the power to compel disclosure of any non-privileged materials generated in the investigation. Powers of compulsion do not apply to privileged materials.
