Workplace Investigations

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 trigger could come from several sources, such as a grievance from a current or former employee, a complaint from external sources, a whistleblowing disclosure, or as the result of internal governance measures.

In each case, the employer will need to decide if an investigation is warranted. It may be required by internal policies or regulatory requirements in some circumstances. Consideration must be given to whether an investigation is feasible; for example, is the evidence still in existence and accessible? Are key witnesses still employed or contactable?

If the employer concludes that an investigation is warranted, it should start without unreasonable delay. The first step would usually be to set terms of reference, which outline the purpose and remit of the investigation. These should be closely drafted and continually referred to, to avoid the investigation’s scope expanding when new points arise (as they almost always will). An investigator will also need to be appointed (see question 4).

As mentioned under Question 10, the employer’s duty of care (article 328, Swiss Code of Obligations) also entails the employer’s duty to respect and protect the personality (including confidentiality and privacy) and integrity of employees (article 328 paragraph 1, Swiss Code of Obligations) and to take appropriate measures to protect them.

However, in combination with the right to be heard and the right to be informed regarding an investigation, the accused also has the right that incriminating evidence is presented to them throughout the investigation and that they can comment on it. For instance, this right includes disclosure of the persons accusing them and their concrete statements. Anonymisation or redaction of such statements is permissible if the interests of the persons incriminating the accused or the interests of the employer override the accused’ interests to be presented with the relevant documents or statements (see question 11; see also article 9 paragraphs 1 and 4, Swiss Federal Act on Data Protection). However, a careful assessment of interests is required, and these must be limited to what is necessary. In principle, a person accusing another person must take responsibility for their information and accept criticism from the person implicated by the information provided.[1]

Only in exceptional circumstances, such as where there is a genuine risk of retaliation. Anonymising a complaint puts the employee under investigation at a significant disadvantage, as they may be unable to properly challenge the evidence against them. It can also impair the effectiveness of the investigation. Employers should, therefore, not provide any guarantees of confidentiality to complainants or to employees who are to act as witnesses. That said, employers should think carefully about any necessary disclosure of names or facts. This can be particularly relevant where the witness is subordinate to the employee being investigated.

In addition to the above-mentioned statutory confidentiality obligations, separate non-disclosure agreements can be signed. In an internal investigation, the employee should be expressly instructed to maintain confidentiality.

Only to a limited extent. As a matter of law, NDAs cannot prevent a worker from making a protected disclosure, or reporting a crime to the police. As a matter of the regulatory obligations of solicitors, NDAs should not be used in other ways, including as a means of influencing the content of disclosures, or by using warranties, indemnities and clawback clauses in a way that is designed to, or has the effect of, improperly preventing or inhibiting permitted reporting or disclosures (see the SRA’s warning notice on the use of NDAs).
