Workplace Investigations

The former Act on the House for Whistleblowers already provided for several preconditions that a whistleblowing procedure must meet. For example, internal reporting lines must be laid down, as well as how the internal report is handled, and an obligation of confidentiality and the opportunity to consult an advisor in confidence must be applied. Employers are obliged to share the whistleblowing policy with employees, including information about the employee's legal protection. The employee who reports a suspicion of wrongdoing in good faith may not be disadvantaged in their legal position because of the report (section17e/ea Act House of Whistleblowers).

The starting point is that an employee must first report internally, unless this cannot reasonably be expected. If the employee does not report internally first, the House for Whistleblowers does not initiate an investigation. The House for Whistleblowers was established on 1 July 2016 and has two main tasks: advising employees on the steps to take and conducting an investigation in response to a report.

The Act on the Protection of Whistleblowers, which entered into force in 2023, introduced several changes, of which the most relevant are:

• Abolition of mandatory internal reporting: the obligation to report internally first is abolished. Direct external reporting is allowed, such as to the House for Whistleblowers or another competent authority. When reporting externally, the reporter retains his protection. However, reporting internally first remains preferable and will be encouraged by the employer as much as possible.
• Expansion of prohibition on detriment: the prohibition on detriment already included prejudicing the legal position of the reporter, such as suspension, dismissal, demotion, withholding of promotion, reduction of salary or change of work location. It now also includes all forms of disadvantage, such as being blacklisted, refusing to give a reference, bullying, intimidation and exclusion. 
• Stricter time limit requirements for internal reporting: the reporter must receive an acknowledgement of receipt of the report within seven days and the reporter must receive information from the employer on the assessment of their report within a reasonable period, not exceeding three months.

• Extension of the circle of protected persons: not just employees, but third parties who are in a working relationship with the employer are now also protected, such as freelancers, interns, volunteers, suppliers, shareholders, job applicants and involved family members and colleagues.

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.

The fundamental right to a fair hearing entails that the investigation findings must be disclosed to the employee under investigation at least once, so that they are given the opportunity to respond to them. Under Dutch administrative or criminal law, there are no general provisions requiring disclosure of investigative findings to regulators or criminal authorities. Certain specific provisions, however, apply, for example, in reportable incidents at financial institutions or certain HSE incidents that need to be disclosed to relevant regulatory authorities. Regulatory and criminal authorities, however, do have broad investigative powers enabling them to order the provision of data from subjects or involved parties in investigations they are conducting. Such information may also comprise investigation findings and underlying documents, such as interview records. If such interview records are subject to legal privilege (see question 14), they are typically not subject to disclosure to the relevant authorities.

Under Dutch civil law, a party that possesses certain records (such as investigation findings and underlying documents) is generally not required to disclose those to other parties for inspection. Parties are, in principle, not required to share information with third parties, other than relevant authorities (see above).

An exception to this rule is section 843a Dutch Code of Civil Procedure. Under section 843a, a party can be required to produce specific exhibits, if:

• the requesting party has a legitimate interest;
• the request concerns specific and well-defined records or information (ie, no fishing expeditions); and
• the documents pertain to a legal relationship (e.g., a contract or alleged tort; the requested party does not need to be a party to the relevant legal relationship).

If these requirements are met, the requestee should, in principle, disclose the requested information, except for specific exceptions. Such exceptions, which can also be relevant in the context of internal (workplace) investigations, could include confidentiality arrangements and privacy protection, to the extent that this would qualify as a compelling interest. To establish such a compelling interest, the relevant interest should outweigh the requesting party's legitimate interest regarding the requested information. This is a balancing act. Documents that are subject to legal privilege are protected against disclosure.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]
