Workplace Investigations

There are no legal requirements in this respect – it depends on the internal policies or practices at a given working establishment. Based on our experience – an internal investigation usually commences with a preliminary assessment of a reported irregularity. If the preliminary assessment leads to a conclusion that a reported situation may be an irregularity, an investigation is launched by appointing a commission or team that conducts the investigation or selecting an investigator. Then, a plan of investigation is established. Depending on the circumstances, the investigation plan may involve a collection of documents or files, their analysis, and interviews with a victim, witnesses or a subject (although the procedure depends on the type of case, internal rules and practice). At the end of the process, the report is prepared by the commission or team with facts established during the process, recommendations, and other suggestions as to the investigated issue.

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

The circumstances in which an employer commences a workplace investigation may vary, either through a whistleblower, through an internal system, email or phone call; complaints from suppliers, contractors, or customers; or accounts from observations and hearsay. Sometimes, it comes from anonymous complaints. However, it is common for an employer to verify whether the report or complaint is substantiated, partially substantiated, or unsubstantiated, which is sufficient to initiate and commence a workplace investigation.

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.
