Workplace Investigations

There is no general obligation on the part of the employer to disclose to the employee concerned the identity of the complainant, witnesses or other sources of information during the workplace investigation.

However, as described in question 11, the employee must be sufficiently informed of the allegations before a termination based on suspicion of wrongdoing is issued. This may also require disclosing the complainant's or witnesses' identity or other sources of information. In addition, the employer would have the burden of proof in the context of a legal dispute (eg, termination protection proceedings or proceedings about the legality of certain investigation measures) and may have to name witnesses and disclose sources of information.

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]

Workplace investigations that do not require the presence or active cooperation of the employee may also start or continue during the employee's absence due to illness. If the employee's cooperation is required, for example for an interview, the employer can only instruct the employee to participate despite an existing illness if certain narrow conditions are met:

Regarding staff meetings at the company, the German Federal Labour Court has ruled that the employer can only instruct the employee to attend the staff meeting during illness if

• there is an urgent operational reason for doing so, which does not allow the instruction to be postponed until after the end of the incapacity to work; and
• the employee's presence at the company is urgently required and can be expected of him.

Similar rules are likely to apply to the employee's presence for workplace investigations.

Urgent operational reasons that cannot be postponed could exist, for example, if during the employee's absence due to illness, there is a risk that evidence will be lost (eg, where only the employee affected has access to certain files or data) or there is a risk of significant damage to the employer if workplace investigations are stopped until after the employee's return.

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).
