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 the investigation is based on a whistleblower report that falls under the scope of the upcoming rules, the investigators are bound by a strict duty of confidentiality, especially regarding the identity of the report. The rules also provide some procedural deadlines for feeding back to the reporter. Within seven days of receiving the report through an internal reporting channel, the reporting manager needs to send a receipt to the whistleblower. From that moment, the reporting manager has three months to investigate the report and give feedback and an adequate follow-up to the report. Next, the rules offer strong protection against any retaliatory measures the reporter may experience. Regardless, these rules are mostly intended to offer the necessary protection for whistleblowers and to ensure that companies take necessary investigative steps following a report, but they do not include much information about the actual procedure of the investigation besides certain deadlines, nor do they deal with other employees involved (or under investigation).

Evidence obtained in the context of an investigation must specify who provided it and the date it was provided. No retaliatory measures may be taken against the whistleblower for the act of whistleblowing.

In certain cases, the whistleblower report must be forwarded to the judicial authorities (eg, when there is an obligation to assist persons in imminent danger, for serious offences or a disclosure that a vulnerable person is in danger (ie, minors under 15 or a person who is unable to protect themselves)).

If an employee complains to his or her superiors about grievances or misconduct in the workplace and is subsequently dismissed, this may constitute an unlawful termination (article 336, Swiss Code of Obligations). However, the prerequisite for this is that the employee behaves in good faith, which is not the case if he or she is (partly) responsible for the grievance.
