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.

Thai labor laws do not require a workplace investigation to involve participation from trade unions or labour unions. However, it is possible for labour unions established under the Labor Relation Act BE. 2518 (1975) to submit a demand for a collective bargaining agreement (CBA) with employers to get a seat at the table. There was a case where a management union made a CBA with the employer wherein the president of the management union would be involved in any investigation of any manager, who is a union member, under investigation. In that case, the employer must comply with the CBA by informing the president and allowing the president to participate in the investigations.

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).

If the absence is anticipated to be brief, the employer may wait until the employee's return before concluding the investigation. If the employee's absence is expected to be prolonged, the investigator may alter the time of meetings or request that the employee submits a witness statement. The key point would be that all necessary measures should be taken to give the employee a chance to participate.
