Workplace Investigations

A works council or a trade union does not have a role in the investigation.

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.

In general, investigation materials, including findings, that includes personal data should only be processed by the personnel of the organisation who are responsible for internal investigations. However, it may in some situations be required by applicable legislation that findings are disclosed to competent authorities for the performance of their duties, such as conducting investigations in connection with malpractice and violations of the law.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]

The investigation findings should be disclosed to a limited group of persons who are involved in the investigation, and for which the findings are useful. For example, an HR manager who needs to record the findings in the employee’s record, the police if the employer decides to proceed further with a criminal claim, the court if requested by that court, or if there is a court case related to the violations of the employee.

Interview records should be kept confidential and private. There is a risk of disclosure because the information in the records may be beneficial to one but damaging to others. If the interview records are leaked to others who are not involved in the investigation, it may affect the work environment in the workplace and the protection of witnesses.
