Workplace Investigations

Generally speaking, a workplace investigation does not require the involvement of a trade union (on the assumption that no specific union agreement has been reached at a company level to entitle trade unions to specific forms of consultation or involvement in workplace investigations, which is not common).

According to section 4 of the Workers’ Statute, as stated above, the involvement of the trade union is necessary regarding the installation and use of specific equipment (such as cameras, switchboards, software) that potentially allows the employer to remotely monitor working activity, and which can be done only with prior agreement of the unions (or authorised by the labour inspectorate).  The union agreement must be made before the installation of the system, and therefore would normally be already in place when an investigation starts.

Pursuant to the WB Decree (Art. 4), union representatives (or external unions) should be “heard” before the employer activates a WB reporting channel[1].

An employee who is a member of a works council or trade union has the right to seek assistance from the works council or trade union representative (whichever is applicable) and have the works council or trade union involved in resolving the grievances.

For unionised companies, the grievance procedure and the role of the union representative are usually set out in the collective agreement entered into between the company and the works council or trade union. In some organisations, the employee handbook or grievance policy will also state when the trade union representative will be involved in the investigation process.

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.

Although there are no specific rules stating an investigation must be suspended if the employee under investigation goes off sick, practically speaking, this may slow down the process. Indeed, the employer would not be in the position to “force” the employee, while he or she is absent from work, to physically attend meetings, although they may ask for the employee’s availability to attend remote interviews (eg, via videoconference).

There is case law regarding an employee’s sickness during a disciplinary procedure (i.e. the procedure described above in point 3): according to certain rulings, if an employee, as per his or her rights, asks to submit an oral defence, but then falls sick, this does not prevent the employer from completing the procedure (and taking disciplinary action), unless the employee proves that his or her sickness prevents him or her from physically attending the meeting (being said that, above all if the procedure ends with a dismissal, a case-by-case analysis on how to manage such situations is highly recommended).

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).
