Workplace Investigations

There is no specific legal regulation for internal investigations in Switzerland. The legal framework is derived from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights. Depending on the context of the investigation, additional legal provisions may apply; for instance, additional provisions of the Swiss Federal Act on Data Protection or the Swiss Criminal Code.

In the United States, any combination of legislation at the federal, state and local level, as well as judicial opinions and regulatory guidance interpreting those statutes, may impose obligations on relevant employers to undertake a timely internal investigation in response to complaints of workplace misconduct and to promptly implement remedial measures, where appropriate.

An employer’s written policies often also set forth the company’s expectations for how its employees, partners, vendors, consultants or other third parties will conduct themselves in carrying out the business of the company, and these policies may include protocols setting forth the parameters for an investigation in the event of potential non-compliance. Such investigatory roadmaps are often described in, for example, employee handbooks or a company’s policy against discrimination and harassment.

Due to the patchwork nature of employment and related laws, it is not possible to cover every investigation scenario or related legislation in this guide. Employers should instead consult with experienced employment attorneys in their state to ensure compliance with the applicable legal and regulatory regimes. 

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]

Only the findings should be shared with the complainant and the subject of the complaint.
