Workplace Investigations

Yes, NDAs can be used for this purpose. However, employers in the Netherlands often rely on general confidentiality obligations that the relevant employee already has to adhere to vis-à-vis their employer, for example in the employment agreement or collective labour agreement, if applicable. It is good practice to reiterate the confidential nature of any interview and its contents, and the existence of the investigation as such, to avoid any alleged confusion as to the confidential nature of investigative procedures later on.

In addition to the above-mentioned statutory confidentiality obligations, separate non-disclosure agreements can be signed. In an internal investigation, the employee should be expressly instructed to maintain confidentiality.

There are a lot of possibilities for grievances that employees can raise during an investigation. A grievance, for instance, could be that a certain person is not interviewed, while the employee wanted this person to be interviewed in order to have a thorough investigation. In such a case the investigator needs to assess this grievance.

There is no general rule how to react to a grievance and there is also no general obligation to respond to a grievance. There needs to be a case by case assessment based on which further action is or isn't needed.

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).
