Workplace Investigations

Once the decision to undertake a workplace investigation has been made, it is important to decide who is the most appropriate person to conduct the investigation. For the investigation process to run smoothly a single lead investigator should be selected, although they may work with a larger team. The lead investigator and investigation team can be internally or externally appointed.

In deciding whether to appoint an external investigator an employer should consider:

• the nature of the allegations;
• the seniority of the respondent;
• whether a fair investigation can be conducted internally without any actual or perceived bias;
• whether there is a dedicated HR department with someone who has the required capability, skills and experience to conduct the investigation; and
• whether the employer wants the investigation to be covered by legal professional privilege.

If the employer decides to investigate the matter internally without appointing a third party, then the investigator does not need to have any specific qualifications. However, it is prudent to confirm that the investigator has the time and skills to conduct the investigation and that they can be objective.   

Workplace investigations, if they are to be of value, must be conducted by an expert, professional and independent party. To safeguard the independence of the investigation, it is crucial that neither the contractor nor any other third party can influence how the investigation is to be conducted or how the outcome should be reported. The investigation must be conducted according to the protocol drawn up at the start and the investigator must not be involved in the follow-up to the outcome.

There is an ongoing discussion of whether lawyers can conduct an objective and independent investigation, due to the bias inherent to their profession. On the other hand, investigation bureaus or committees are also not necessarily independent, as they are not regulated and not subject to disciplinary law.

The examinations can be carried out internally by designated internal employees, by external specialists, or by a combination thereof. The addition of external advisors is particularly recommended if the allegations are against an employee of a high hierarchical level[1], if the allegations concerned are quite substantive and, in any case, where an increased degree of independence is sought.

To ensure procedural fairness, the allegations must be put to the respondent in writing in advance of the investigation interview. The allegations must be specific, but the respondent does not need to be provided with a copy of the original complaint. The respondent should also be informed that if the allegations are substantiated they may result in disciplinary action up to and including the termination of the employee’s employment.

An implicated person is typically provided with a summary description of the scope of the investigation and, hence, the allegations against such an employee (if any). This is usually done in the interview invite sent to the relevant interviewee, which also provides an opportunity to prepare for an interview and (if relevant) seek legal advice.

As a result of the employer's duty of care (article 328, Swiss Code of Obligations), employees under investigation have certain procedural rights. These include, in principle, the right of the accused to be heard. In this context, the accused has the right to be informed at the beginning of the questioning about the subject of the investigation and at least the main allegations and they must be allowed to share their view and provide exculpatory evidence.[1] The employer, on the other hand, is not obliged to provide the employee with existing evidence, documents, etc, before the start of the questioning.[2]

Covert investigations in which employees are involved in informal or even private conversations to induce them to provide statements are not compatible with the data-processing principles of good faith and the requirement of recognisability, according to article 4 of the Swiss Federal Act on Data Protection.[3]

Also, rights to information arise from the Swiss Federal Act on Data Protection. In principle, the right to information (article 8, Swiss Federal Act on Data Protection) is linked to a corresponding request for information by the concerned person and the existence of data collection within the meaning of article 3 (lit. g), Swiss Federal Act on Data Protection. Insofar as the documents from the internal investigation recognisably relate to a specific person, there is in principle a right to information concerning these documents. Subject to certain conditions, the right to information may be denied, restricted or postponed by law (article 9 paragraph 1, Swiss Federal Act on Data Protection). For example, such documents and reports may also affect the confidentiality and protection interests of third parties, such as other employees. Based on the employer's duty of care (article 328, Swiss Code of Obligations), the employer is required to protect them by taking appropriate measures (eg, by making appropriate redactions before handing out copies of the respective documents (article 9 paragraph 1 (lit. b), Swiss Federal Act on Data Protection)).[4] Furthermore, the employer may refuse, restrict or defer the provision of information where the company’s interests override the employee’s, and not disclose personal data to third parties (article 9 paragraph 4, Swiss Federal Act on Data Protection). The right to information is also not subject to the statute of limitations, and individuals may waive their right to information in advance (article 8 paragraph 6, Swiss Federal Act on Data Protection). If there are corresponding requests, the employer must generally grant access, or provide a substantiated decision on the restriction of the right of access, within 30 days (article 8 paragraph 5, Swiss Federal Act on Data Protection and article 1 paragraph 4, Ordinance to the Federal Act on Data Protection).
