Workplace Investigations

A preventive suspension pending investigation is allowed under the law, provided that the continued employment of the subject of the investigation poses a serious and imminent threat to the life or property of the employer or other employees. Additionally, the period of preventive suspension pending investigation should not last longer than 30 days. However, should the employer wish to extend this period, the employer must pay the employee’s wages and other benefits. The employee is under no obligation to reimburse the amount paid to them during the extension if the employer should, later on, decide to dismiss the employee after the completion of the process.

In practice, the notice of preventive suspension is issued simultaneously with the first notice or the notice to explain after the employer has conducted its fact-finding investigation and has reason to believe that the employee must be held accountable for his or her actions.

Since placing an employee under preventive suspension requires the existence of a serious and imminent threat to the life or property of the employer or other employees, some employers opt to place the employee or employees involved on agreed paid leave. This will allow the employer to conduct an unhampered workplace investigation while the investigated employee is still able to receive his or her full salary during this period. The exact period of paid leave may be agreed upon by the employer and the employee, but ideally it should not last for more than thirty days.

In general, an employee in the private sector may be temporarily suspended for a short period with pay and other benefits during a workplace investigation. The room for suspension without pay is, by contrast, very limited. An applicable collective bargaining agreement may impose additional restrictions on the right to temporary suspend an employee. The suspension should be limited in time and only be in force during the investigation, but can be repeated for (multiple) additional short periods if necessary to conclude the investigation. An assessment needs to be made on a case-by-case basis as suspension in some cases may be considered unlawful. If not executed with sufficient consideration of the employee’s interests, it may be considered a constructive dismissal or a breach of the employer’s work environment obligations. If the employee is unionised, trade unions sometimes request that the employer initiates consultations as part of a decision to suspend an employee.

In the public sector, the right to suspension is limited. There are also special regulations regarding the suspension of certain employees, for example, employees who are employed as permanent judges.

It is possible to suspend an employee during a workplace investigation.[1] While there are no limits on duration, the employee will remain entitled to full pay during this time.

Since neither consent nor the presence of the employee is material to the conduct of the investigation, his or her absence would not, in practice, imperil the conduct of the investigation.

As previously discussed, because the employer exercises a wide latitude of discretion in conducting workplace investigations, the employer may choose to proceed with the investigation despite the absence of the employee being investigated. Since the proceeding is only in the investigation phase, the statutory right of the employee to be heard is not violated, even if the investigation takes place without his or her participation.

The employer is responsible for the employee’s work environment during the investigation. The employer must assess the situation and the impact on the employee’s health and may, depending on the situation, have to postpone certain investigative measures, such as interviewing the employee in question. The investigation may even have to be completed without the employee participating.

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).
