Workplace Investigations

The law does not cover this issue, apart from whistleblower regulations, as it should be regulated by the employer in their internal rules. The employer should ensure all participants of the investigation keep information related to it secret, as long as is necessary for the investigation (or even longer, if required by law concerning personal data or other specially protected information). Reputation, personal data and the personal rights of other people cannot be breached during the proceedings and this should be protected.

Moreover, according to the Draft Law – a whistleblower’s personal data should be kept confidential. It can only be disclosed if law enforcement authorities require it. Also, confidentiality should be guaranteed for the subject and other interested persons.

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]

Workplace investigations should be conducted in a strictly confidential manner to preserve the integrity and professionalism of the investigation and to protect the identity of the employee under investigation. This means that all information gathered, received, and shared during the investigation (ie, the subject employee and any material witnesses) should only be disclosed on a need-to-know basis.

It depends on the circumstances of the revealed issue and the employer’s compliance culture. Normally, if a new issue is revealed during the investigation, it should be analysed and investigated if appropriate.

There are no regulations in this regard in the Swiss employment law framework. However, in criminal proceedings, the rules regarding accidental findings apply (eg, article 243, Swiss Criminal Procedure Code for searches and examinations or article 278, Swiss Criminal Procedure Code for surveillance of post and telecommunications). In principle, accidental findings are usable, with the caveat of general prohibitions on the use of evidence.

If unrelated matters are revealed during the investigation, the employer should consider whether an investigation is needed. If necessary, the employer should decide whether it is appropriate to incorporate the new matters into the scope of the existing investigation by expanding the terms of reference. However, such action may not be appropriate if different individuals are involved or the inclusion of a new unrelated matter would unduly complicate or delay the progress of the existing investigation. If that is the case, the employer should investigate that matter separately.

Also, as detailed in article 19 of the 2015 Criminal Code of Vietnam, there is a legal duty on any person who is aware that a certain violation is being committed or has been committed to report it to the police unless otherwise provided for under law. Failure to comply with this requirement may lead to criminal liability for the offender.
