Workplace Investigations

Evidence obtained in the context of an investigation must specify who provided it and the date it was provided. No retaliatory measures may be taken against the whistleblower for the act of whistleblowing.

In certain cases, the whistleblower report must be forwarded to the judicial authorities (eg, when there is an obligation to assist persons in imminent danger, for serious offences or a disclosure that a vulnerable person is in danger (ie, minors under 15 or a person who is unable to protect themselves)).

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.

A criminal investigation always takes precedence over other investigations. However, this does not mean that the internal investigation has to stop. It can and should continue, and the report drawn up upon completion of the investigation could be used by the authorities in the criminal investigation. In some cases, especially when privilege does not apply, police or regulatory authorities may request that the employer share such evidence. However, even when privilege does apply, there is no certainty that the evidence would not have to be communicated to certain authorities.

Some administrative authorities often challenge the application of legal privilege or try to reduce its scope. For example, the French financial markets authority (AMF) regularly puts forward its view of legal privilege, according to which an email where a lawyer is only copied (and is not one of the main recipients) in from one of their clients is not confidential and can therefore be disclosed in proceedings. However, if the AMF investigators impose disclosure of privileged documents, this should result in the annulment of the investigation procedure. By way of exception, legal privilege cannot be invoked against certain other authorities, such as the URSSAF (authority in charge of collecting social security contributions) or the DGCCRF (directorate-general for competition, consumer protection and anti-fraud investigations). Where legal privilege is enforceable, the judge must first determine whether the documents constitute correspondence relating to defence rights and, second, must cancel the seizure of documents that they find to be covered by legal privilege due to the principle of professional secrecy of relations between a lawyer and their client and the rights of defence.

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).
