Workplace Investigations

Since there is no mandatory law (yet) that provides a framework for workplace investigation interviews, there are also no special protective regulations for employees acting as witnesses.

Employees have a contractual duty to participate in interviews – be it as a suspect or as a witness – as part of workplace investigations. The employee must provide truthful information based on his duty of loyalty if:

• the questions relate to his area of work;
• the employer has an interest worthy of protection in obtaining the information; and
• the requested information does not represent an excessive burden for the employee.

Whether such a burden can be assumed when the employee must make statements by which he may incriminate himself is disputed in German case law and legal literature. The German Federal Labour Court has not yet decided on this question. Since an internal workplace investigation interview is an interview under private law and not under criminal law, there are, in our view, good arguments that the employee must also make a true statement even if he incriminates himself, provided his area of work is concerned. However, some labour courts assume that in these cases such a statement could not be used in criminal proceedings.

Interviewing co-workers is often conducted in internal investigations. Company employees are generally required to cooperate with company investigations, especially those who are in a position to instruct and supervise employees, or those who are responsible for maintaining corporate order, since cooperation with an investigation is itself the fulfilment of their duty to the company. Other employees are not compelled to cooperate with such an investigation unless it is deemed necessary and reasonable. No specific legal protection is provided for testifying in an investigation.

Due to the employee's duty of loyalty towards the employer and the employer's right to give instructions to its employees, employees generally must take part in an ongoing investigation and comply with any summons for questioning if the employer demands this (article 321d, Swiss Code of Obligations). If the employees refuse to participate, they generally are in breach of their statutory duties, which may lead to measures such as a termination of employment.

The question of whether employees may refuse to testify if they would have to incriminate themselves is disputed in legal doctrine.[1] However, according to legal doctrine, a right to refuse to testify exists if criminal conduct regarding the questioned employee or a relative (article 168 et seq, Swiss Criminal Procedure Code) is involved, and it cannot be ruled out that the investigation documentation may later end up with the prosecuting authorities (ie, where employees have a right to refuse to testify in criminal proceedings, they cannot be forced to incriminate themselves by answering questions in an internal investigation).[2]

As seen in question 6, the employee must participate in interviews requested by the employer under certain circumstances. Generally, the employee must provide truthful information even if it is incriminating.

The raising of a grievance by the employee does not directly affect the workplace investigation (ie, the investigation does not have to be stopped and the employee's obligation to provide truthful information continues). This may change, however, once the court decides that certain measures were conducted unlawfully and must, therefore, cease.

Whether or not an investigation should be suspended when an employee under investigation files a complaint depends on the specific circumstances. There is no legal requirement to suspend the investigation.

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).

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 company will seek a physician's diagnosis and opinion and determine whether to proceed with the investigation. If an employee’s mental health suffers because of the investigation, the company may be charged with a violation of its duty of care.

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).
