Workplace Investigations

The circumstances in which an employer commences a workplace investigation may vary. However, it is common that an employer will consider it necessary to commence a workplace investigation upon receipt of a complaint concerning a fellow employee. Sometimes, the complaint may be made anonymously. If the employer considers there to be substance in the complaint, it may commence an investigation to find out the truth of the matter, resolve the complaint and, if necessary, improve its systems and controls to prevent the reoccurrence of any misconduct.

A workplace investigation may be warranted if the employer receives an enquiry from a regulator concerning its affairs or an employee’s conduct. The investigation findings could enable the employer to respond to the regulator (which could be a mandatory obligation) and at the same time assess its risk exposure.

There are no legal requirements in this respect – it depends on the internal policies or practices at a given working establishment. Based on our experience – an internal investigation usually commences with a preliminary assessment of a reported irregularity. If the preliminary assessment leads to a conclusion that a reported situation may be an irregularity, an investigation is launched by appointing a commission or team that conducts the investigation or selecting an investigator. Then, a plan of investigation is established. Depending on the circumstances, the investigation plan may involve a collection of documents or files, their analysis, and interviews with a victim, witnesses or a subject (although the procedure depends on the type of case, internal rules and practice). At the end of the process, the report is prepared by the commission or team with facts established during the process, recommendations, and other suggestions as to the investigated issue.

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]

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.

This may prolong the investigation, as the employee may be unable to participate for a time (if the employee is not able to work, in many cases he or she will not be able to participate in proceedings that requires some level of engagement and psychophysical ability). Also, an employee is protected against termination of an employment contract with notice during sick leave. During such a period, the employer may only terminate his or her employment contract without notice (with immediate effect).

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).
