Workplace Investigations

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]

As there is no unified data protection regime, privacy protections stem from a patchwork of federal and state privacy laws which impose limits on the extent to which an employer can collect information from its employees in connection with an internal investigation. Whether specific conduct violates an employee’s rights is a very fact-specific inquiry requiring the application of relevant state laws and a regulatory regime. 

In most circumstances, an employer is free to conduct searches of its workplace and computer systems in the course of investigating potential wrongdoing. Such searches are generally not protected by personal privacy laws because workspaces, computer systems and company-issued electronic devices are often considered company property. Many companies explicitly address this in written corporate policies and employment agreements. Employees who use their own electronic devices for work should be aware that work-related data stored on those devices is generally considered to belong to the employer (as a matter of best practice, employers should generally prohibit or at least advise employees against using personal devices for work and to maintain separate work devices, where possible).

These broad investigatory powers notwithstanding, the ability of an employer to conduct searches in furtherance of an internal investigation is not unlimited. For example, if an employer seeks to obtain or review work-related data from an employee’s personal device, the employer must be careful to exclude any personal data. Certain states also prohibit an employer from requiring an employee to disclose passwords or other credentials to his or her personal email and social networking accounts, but permit an employer to require employees to share the content of personal online accounts as necessary during an interview while investigating employee misconduct.

L.4990/2022 explicitly states that the exercise of employee rights that refer to consulting from representatives or trade unions and protection against any detrimental measure that results from those consultations does not affect the implementation of any legal provisions. The autonomy of social partners and their right to enter into collective agreements regardless of the level of protection provided by L.4990/2022[7] is also unaffected.

Under L.4808/2021, legal persons and associations of persons, including trade unions, that have a legitimate interest in doing so may, with the consent of the complainant, bring an action in the complainant’s name before the competent administrative or judicial authorities. They may also intervene in their defence[8].

In general, works councils and trade unions are not very common in Switzerland and there are no statutory rules that would provide a works council or trade union a right to be informed or involved in an ongoing internal investigation. However, respective obligations might be foreseen in an applicable collective bargaining agreement, internal regulations or similar.

Employers generally have no obligation to inform employees of their right to union representation or to ask if they would like a union representative present during the interview. Union employees may insist, however, that a union representative attend any investigatory interview that could lead to the employee’s punishment, although the union representative may not interfere with the interview.
