Workplace Investigations

As discussed in question 11, an employer owes an implied obligation of trust and confidence towards its employees under common law. This means that an employer cannot disregard a genuine complaint made by an employee even if the employee is under internal investigation. The employer may have put in place an employee grievance handling policy, which should be followed when handling the employee’s grievance.

If the grievance raised relates to how the workplace investigation is being conducted (for example, it is alleged that the investigator has a conflict of interest or is biased), the employer should consider suspending the investigation until this grievance is properly addressed to ensure fairness. However, if the grievance is nothing but an attempt to delay or hinder the investigation, the employer may be entitled to proceed with the investigation regardless. The employer should therefore carefully assess the nature and validity of any grievance raised in each case. The employer should also consider its rights under the employment contract if the employee is being uncooperative or obstructive.

In the context of private internal investigations, grievances initially raised by the employee do not usually have an impact on the investigation.

However, if the employer terminates the employment contract due to a justified legal complaint raised by an employee, a court might consider the termination to be abusive and award the employee compensation in an amount to be determined by the court but not exceeding six months’ pay for the employee (article 336 paragraph 1 (lit. b) and article 337c paragraph 3, Swiss Code of Obligations). Furthermore, a termination by the employer may be challenged if it takes place without good cause following a complaint of discrimination by the employee to a superior or the initiation of proceedings before a conciliation board or a court by the employee (article 10, Federal Act on Gender Equality).

If the employee under investigation goes off sick, the employer should ascertain the medical condition of the employee and when he or she is likely to return to fitness. If the employee is unlikely to return to work for a reasonable time, the employer should consider what adjustments can be made to the investigation process to continue with the investigation. If the employee’s input is necessary for the conclusion of the investigation, the employer may invite the employee to provide information by way of a written questionnaire or to attend a virtual meeting. However, the employee may not necessarily agree to these proposals, especially if he or she is unwell. In such circumstances, the employer may not be able to conclude the investigation in the absence 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).
