Workplace Investigations

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]

Interviewers, investigators, interviewees or any others involved in the investigation are often bound by a reinforced confidentiality obligation, particularly when the internal investigation is triggered by a whistleblower alert. In addition, every person that comes to know of the investigation, facts or people involved is bound by an obligation of discretion. Furthermore, investigators should specifically be trained for interviews and be reminded of their obligations relating to the investigation.

The investigators will need to determine the order of the tasks to be carried out in the investigation, as this will have a significant impact on confidentiality management. Should they start with the hearings or a review of documents? The answer may depend on the subject matter of the investigation. It is advisable to first review the documentation before organising interviews, particularly to avoid the destruction of certain documents by employees acting in bad faith or by those wishing to erase the traces of alleged wrongdoing. Sometimes, however, it is possible to start with the interviews, especially in the case of harassment, as there may be no documents to review. If the decision is taken to conduct the documentation review after the interviews, it could be useful to ask the employees involved to sign a document stating that they must preserve and retain documents, meaning that if they delete or destroy documents, they would be acting against the company and in breach of the law.

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]
