Workplace Investigations

Neither the works council nor the trade unions have any right to be informed or involved in the investigation. It is the employer who is responsible for carrying out the investigation. However, when the investigation is triggered due to a works council issuing an alert relating in particular to a “serious and imminent danger”, one member of the works council must be involved in the investigation process.

Employee representative bodies are not entitled to be informed about or to participate in the preliminary investigation. The works council is only entitled to participate in disciplinary proceedings after a formal accusation has been made against the employee.

A copy of the accusation should be sent to the works council (if any) and if the employee is a trade union member, to the respective trade union. After the instruction phase of the procedure has ended (where the employer has to hear the witnesses identified by the employee in his written defence and file any other sources of information that have been requested), the employer should provide a copy of the disciplinary procedure to the works council (if any) and the respective trade union, if the employee is a member. These employees’ representatives will then have five business days to issue their opinion on the matter.

Finally, a copy of the final decision must also be sent to these bodies.

There is no legal right for the interviewee to be assisted by a representative from the works council.

In general, works councils and trade unions are not very common in Switzerland and there are no statutory rules that would provide a works council or trade union a right to be informed or involved in an ongoing internal investigation. However, respective obligations might be foreseen in an applicable collective bargaining agreement, internal regulations or similar.

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.

These procedures are independent and autonomous, and the law does not provide any particular rules to ensure coordination. This raises particular concerns when an employee is subject to a criminal investigation in secret, as the employer will be unable to access any evidence from the criminal procedure to begin an internal investigation or disciplinary procedure against the employee.

On the other hand, considering the short statutes of limitation to enforce disciplinary action, it may prove impossible to wait for the outcome of the criminal or regulatory investigation to decide if a disciplinary procedure should also be enforced, because by the time the employer is fully aware of the facts, the statutes of limitation may have already expired.

However, both the judge in a criminal procedure and the regulator have the public authority to order the employer to share any findings within the scope of the investigation or disciplinary procedure.

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).
