Workplace Investigations

First, the employer should appoint an investigator or investigative team that will be responsible for conducting the investigation. Next, the employer or the investigators might think about communicating with the involved employees. It depends on the situation if this is a good idea or not. In general, it can be recommended that the employer is transparent towards the involved employees and openly communicates about the (start of the) investigation process. This is definitively the case if it is already clear that the involved employees are under scrutiny because of their actions. In this case, the actual investigation can begin with a hearing of the involved employees. However, if there is a risk that employees will hide or destroy evidence or will collude to prevent the employer from finding the truth, the investigation can also start without any communication. In this case, it would be better to start collecting evidence before hearing from the employees involved.

When a report of wrongdoing is brought to the employer's attention, whether through a whistleblower or another channel, and an internal investigation is expected, it may be either mandatory or optional, depending on the facts of the alleged wrongdoing.

The investigation will be mandatory when the alleged wrongdoing relates to an ethical issue according to anti-corruption regulations, the employer’s duty of due diligence regarding, for example, human rights or environmental matters, or where the works council has issued an alert relating to a “serious and imminent danger” (or to “fundamental human rights”), but also whenever it relates to the employer's obligation to ensure employee safety (eg, moral or sexual harassment).

If the investigation is not mandatory, it is up to the employer to decide whether or not to carry out the investigation. Several key questions can help the employer determine whether or not it is appropriate to carry out an investigation, such as:

• What are the benefits of doing nothing? The company will have to draw up a list of the pros and cons of an investigation, bearing in mind that in some cases a poorly conducted investigation could make the situation worse;
• What is the priority (eg, obtaining or securing evidence, or correcting the irregularity)?
• What rules or codes of ethics must the company comply with?
• Should external legal counsel only advise the company or should they play a major role in the investigation process by becoming an investigator?

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 this occurs, there is a risk that any measure resulting from the investigation (eg, a dismissal) can be (wrongly) interpreted as discrimination based on the illness of the employee. However, if the employer can prove that the measure is not related to the illness but solely related to the investigation (which is also not related to the illness), there may be no discrimination. The sickness of the employee may prevent the continuation of the investigation because, for example, it becomes impossible to hear from the employee. In this instance, the investigation can be suspended, postponed or extendeded until the employee returns. If it is a long-term absence, this could lead to a disproportionate amount of time to complete the investigation. Therefore, the employer should take any necessary steps to invite the ill employee to a hearing anyway (eg, through digital means). If the employee unreasonably refuses (several) of these invitations, it could be argued that the employee is wilfully boycotting the investigation and therefore forfeits his or her opportunity to be heard.

The investigation will likely be able to continue with the other employees and, as soon as the employee under investigation returns from sick leave, they will be able to be interviewed.

However, as disciplinary sanctions are time-barred after two months from the moment the misconduct was committed or from when the employer becomes aware of it, if the sick leave lasts for the whole of that period, the investigation must be conducted anyway. In this instance, the investigator can ask the employee to attend the interview despite being on sick leave or arrange for the interview to take place using other means (eg, conference call). As a last resort, a questionnaire can be sent to the employee, but the pros and cons must be assessed as this is a way of information gathering that carries a certain amount of risk, could be less reliable and is of less probative value.

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).
