Workplace Investigations

GDPR and the provisions of L. 4624/2019 regulate the gathering of physical evidence from a data protection perspective, providing, among other things, that personal data should be processed with transparency and to the extent necessary for the investigation.

L.4990/2022 on the protection of persons who report breaches of Union law regulates data protection issues in the context of whistleblowing investigations, mainly to safeguard confidentiality throughout the investigations.  

The Swiss Federal Act on Data Protection applies to the gathering of evidence, in particular such collection must be lawful, transparent, reasonable and in good faith, and data security must be preserved.[1]

It can be derived from the duty to disclose and hand over benefits received and work produced (article 321b, Swiss Code of Obligations) as they belong to the employer.[2] The employer is, therefore, generally entitled to collect and process data connected with the end product of any work completely by an employee and associated with their business. However, it is prohibited by the Swiss Criminal Code to open a sealed document or consignment to gain knowledge of its contents without being authorised to do so (article 179 et seq, Swiss Criminal Code). Anyone who disseminates or makes use of information of which he or she has obtained knowledge by opening a sealed document or mailing not intended for him or her may become criminally liable (article 179 paragraph 1, Swiss Criminal Code).

It is advisable to state in internal regulations that the workplace might be searched as part of an internal investigation and in compliance with all applicable data protection rules if this is necessary as part of the investigation.

As a first step, the employer should ask for the employee’s permission to access their possessions and files. Employment contracts and internal labour regulations may include provisions regarding an employer’s access to employees’ documents created and kept for business purposes or related to business activity.

The basic rule is that the employer may not search private data during internal investigations.

If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

For workplace violence and harassment investigations, depending on the outcome of the internal investigation, the employer may adopt certain measures including, for example, recommendations to the employee under investigation, changes to the employee’s working hours and transfer to another department.

If the employer decides to terminate the employment relationship, without having previously followed existing corporate policies regarding reporting procedures or without having provided the alleged perpetrator with the right to be heard, the dismissal could be deemed invalid. In any case, the measures adopted should be appropriate and proportional to the act committed.

If the investigation uncovers misconduct, the question arises as to what steps should be taken. Of course, the severity of the misconduct and the damage caused play a significant role. Furthermore, it must be noted that the cooperation of the employee concerned may be of decisive importance for the outcome of the investigation. The possibilities are numerous, ranging, for example, from preventive measures to criminal complaints.[1]

If individual disciplinary actions are necessary, these may range from warnings to ordinary or immediate termination of employment.
