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].

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.

Generally speaking, even if the investigation leads to evidence of a criminal offence, the employer does not have to inform public authorities (citizens and private entities do not have an obligation to report crimes they discover). The existence of any obligations to report to regulatory authorities (eg, banking and insurance regulatory authorities) should be investigated on a case-by-case basis.

The internal procedures of the company – as adopted by the company in the framework of legislation on the administrative or quasi-criminal vicarious liability of legal entities – may require the findings to be disclosed to certain internal bodies or committees.

As said above, the police or public prosecutors (and possibly other public authorities) may have, within their investigatory powers, and in certain circumstances, the power to access internal investigation outcomes (but a case-by-case analysis would be necessary).

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]
