Workplace Investigations

There is no specific legislation regarding a workplace investigation. In general, an employer has the right to investigate incidents at the workplace based on their authority over employees. However, the investigative powers of the employer are among others limited by the general right to privacy, which is also enshrined in Collective Bargaining Agreement No. 81 of 26 April 2002 to protect the privacy of employees concerning the control of electronic online data. If there are official complaints by employees due to sexual harassment, bullying or violence at work,  well-being legislation provides a specific procedure. Also, upcoming whistleblower rules include some specifications for an investigation, but at the time of publication these are not yet final (we refer to is in more detail below). The information below is only valid for workplace investigations in the private sector. The public sector has a set of specific rules and principles, which are outside the scope of this chapter.

Dutch employment law does not provide for a timeframe within which an internal investigation must be launched. However, it is important for an employer who suspects abuse or irregularities, to start an internal investigation without delay. In essence, that means that as soon as management, or – depending on the specific circumstances – the person who is authorised to decide on disciplinary sanctions against a certain employee, becomes aware of a potential abuse or irregularity, all measures to initiate an internal investigation should be taken promptly. If this is not done, the employer may lose the opportunity to take certain disciplinary actions.

The legal framework relating to an investigation by an employer into the acts and omissions of an employee are determined by, among other things, section 7:611 of the Dutch Civil Code (DCC) that stipulates good employer practices; Section 7:660 DCC (right to give instructions to the employee); the European Convention on Human Rights; the Dutch Constitution; the General Data Processing Regulation; and, if the employer uses a private investigation agency, the Private Security Organisations and Detective Agencies Act and the Privacy Code of Conduct for Private Investigation Agencies.

The legal basis from which the employer derives the authority to investigate can be based on the employer's right to give instructions (section 7:660 DCC). Pursuant to this section, the employer has – to a certain extent – the right to give instructions to the employee “which are intended to promote good order in the undertaking of the employer”. In many cases, an investigation of a work-related incident will aim to promote good order within the company. As such, the investigation is trying to:

• find the truth;
• sanction the perpetrator; and
• prevent repetition.

Instructing an employee to cooperate with an internal investigation falls within the scope of the right to instruct.

Subsequently, the employer must behave as a good employer during the investigation, pursuant to section 7:611 DCC. This is coloured by the classic principles of careful investigation: the principle of justification, the principle of trust, the principle of proportionality, the principle of subsidiarity and the principle of equality. Furthermore, the principle of hearing both sides of the argument applies and there must be a concrete suspicion of wrongdoing.

There is no specific legal regulation for internal investigations in Switzerland. The legal framework is derived from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights. Depending on the context of the investigation, additional legal provisions may apply; for instance, additional provisions of the Swiss Federal Act on Data Protection or the Swiss Criminal Code.

A workplace investigation is often a sensitive matter that requires necessary confidentiality to find out the truth discreetly and objectively. Nevertheless, there is often pressure from employees, trade unions or even the media and general public to be transparent and communicate about the case. From a legal perspective, it is not recommended to communicate openly about an ongoing investigation, as this can jeopardise the investigation or the possibility of taking disciplinary measures.

Whistleblower investigations will be bound by a strict duty of confidentiality regarding anything that could reveal the identity of the reporter.

In complaints due to sexual harassment, violence or bullying at work, the prevention adviser is bound by professional secrecy. Consequently, he or she may not disclose to third parties any information about individuals that have come to his or her knowledge in the performance of his or her duties. However, he or she still has the freedom to inform the people concerned to carry out his or her tasks in the procedure.

The principle of due care requires employers to act prudently when it comes to sharing the identity of persons involved, such as complainants and implicated persons; and investigative findings, notably when certain employees may be implicated. As a result, such information is usually shared within an employer to designated departments on a need-to-know basis only. Additional safeguards as to the protection of whistleblowers' identities apply since the Whistleblower Directive (see question 9) was implemented in Dutch law. Also, see question 13 for the confidentiality obligations of employees vis-à-vis their employer.

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]
