Workplace Investigations

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]

Information arising from the initial complaint, interviews and records should be kept as confidential as practically possible while still permitting a thorough investigation. Although an employer must maintain confidentiality to the best of its ability, it is often not possible to keep confidential the identity of the complainant or all information gathered through the investigation process. An employer should therefore not promise absolute confidentiality to any party involved in an internal investigation, including the complainant. The investigator should instead explain at the outset to the complaining party and all individuals involved that information gathered will be maintained in confidence to the extent possible, but that some information may be revealed to the accused or potential witnesses on a need-to-know basis to conduct a thorough and effective investigation.

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]

Once fact-finding is complete, the investigator should discuss his or her notes with in-house or outside counsel and prepare a summary of the process, high-level findings, and a proposed resolution at the counsel’s direction. This report should not include subjective commentary and should also avoid including excessive detail, and generally be treated confidentially during and after the investigation. If the report is requested by regulators or the police, the company should discuss with in-house counsel, and preferably also with outside counsel, how to respond to the request and whether any steps need to be taken to protect any applicable legal privilege.
