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.

Non-disclosure agreements can be made between an employer and employees who are involved in an investigation. This may include investigators and witnesses, apart from the employee under investigation. This minimises the risk of information being leaked, which can affect all parties related to the workplace investigation. However, an NDA is not absolute means to prevent the disclosure of confidential information, as the court has the authority to compel disclosure.

In case there is a parallel criminal or regulatory investigation usually consultation between the investigators and the authorities takes place. Agreements are then sometimes made about the investigation conducted by / for the employer. In some cases, the authorities will ask to stay the investigation. There is no policy from the government on this topic.

There are situations where the authorities can compel the employer to share evidence. This depends on the exact circumstances of the case. For instance if the employer is the suspect in a criminal case.

It does occur that the authorities are given evidence upon request without the authorities having to order the extradition of evidence.  

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).

Employers are not required to wait until the police or regulatory investigations are finished before conducting their disciplinary investigations, but it is necessary to ensure that such internal proceedings do not compromise the integrity of an investigation or result in misrepresentation or a miscarriage of justice. The level of proof for internal disciplinary action is less than the level of proof for criminal proceedings.
