Workplace Investigations

Files and documents that are purely business-related – whether in physical or digital form – may, in principle, be inspected by the employer without restriction. The employee has no right to refuse inspection.

When searching business laptops, computers, phones and e-mail accounts, a distinction must be made as to whether private use is permitted (or at least tolerated) or not: if the employee is allowed to use the items exclusively for business purposes, the employer may monitor and control them. If private use is permitted, the employee's right to privacy must be observed for private files, as must the protection of the secrecy of correspondence. Accordingly, the employer must avoid accessing private documents, files and e-mails. However, a review of private documents, files and e-mails may be permissible in the event of particularly serious violations if the employer's interest in the review outweighs the employee's interest in safeguarding his right to privacy. Generally, employers should allow private use of electronic devices only if employees have previously consented to the terms of use (including searches in certain cases).

A search of the employee's workplace by the employer is, in principle, permissible. However, a search of personal items (eg, bags, clothes, personal mobile phone) is generally only permissible with the employee's consent. Similarly to the review of digital personal data, a search of personal items may be permitted, however, in the event of particularly serious violations if the employer's interest in the search outweighs the employee's right to privacy.

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]

The works council does not have a general right of co-determination on whether and in what way a workplace investigation is carried out. However, workplace investigations may trigger co-determination rights of the works council in specific cases, as outlined below. If co-determination rights come into consideration, the employer must inform the works council about the investigation to put the works council in a position to assess whether or not co-determination rights are affected.

In connection with workplace investigations, the works council may have a co-determination right in the following cases:

• If e-mail accounts and data are screened by using technical devices that are suitable to monitor the behaviour or performance of employees (section 87 paragraph 1 no. 6, BetrVG).
• If, for example, the employer instructs all or a large group of employees to participate in interviews, the co-determination right of the works council regarding the rules of operation of the establishment and the conduct of employees in the establishment (section 87 paragraph 1 no. 1, BetrVG) may be affected.
• If standardised questionnaires are used in employee interviews, provided they are used for a large group of interviewed employees (section 94, BetrVG).

If co-determination rights exist in the specific case, the works council has the right to co-determine the type and structure of the specific investigative measures used (ie, the relevant investigative measure cannot be carried out without the works council's consent). To avoid any conflicts, the employer should set up, together with the works council, general rules about workplace investigations well ahead of any investigation.

Trade unions have no right of co-determination in workplace investigations.

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.
