Workplace Investigations

Failure by an employer to provide the identity of the complainant, witnesses or sources of information seriously impinges upon the employee's right to fair procedure and could result in a flawed investigation.

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]

If an employee goes off sick during the investigation, it is reasonable to adjourn the investigation until the employee is fit to return to work. Difficulties arise if it is a prolonged absence. The absence may necessitate a referral to an occupational health expert and it may be necessary to seek medical advice as to whether the employee can continue to participate in the investigation. It may be that reasonable accommodations should be considered to ensure that the employee can continue to participate. Such situations may impinge on the investigator's ability to conclude the investigation. In that instance, it would be prudent for the investigator to document all attempts to involve the employee in the investigation and to assess whether it can be concluded without the further involvement of the employee.

The time spent on the internal investigation by the employee should be counted as working time[1]. The general statutory and internal company principles on sick leave apply. Sick leave for which the respective employee is not responsible must generally be compensated (article 324a paragraph 1 and article 324b, Swiss Code of Obligations). During certain periods of sick leave (blocking period), the employer may not ordinarily terminate the employment contract; however, immediate termination for cause remains possible.

The duration of the blocking period depends on the employee's seniority, amounting to 30 days in the employee's first year of service, 90 days in the employee's second to ninth year of service and 180 days thereafter (article 336c paragraph 1 (lit. c), Swiss Code of Obligations).
