Workplace Investigations

If any sources of information used within an investigation include privileged data, they may be redacted to safeguard third parties' rights. However, where disclosure of that data is necessary for the employee to understand why he or she is being accused, it may be necessary to reveal those elements. Otherwise, the employee may argue that their rights were affected and, for that reason, the disciplinary procedure – and any possible sanction – should be deemed null and void.

Litigation privilege may attach to investigation materials if there was a reasonable prospect of litigation at the time of the creation of the materials, and the materials were created for the dominant purpose of a pending or contemplated litigation.

Legal advice privilege may attach to investigation materials if the materials were created to seek or obtain legal advice; or if the materials contain legal advice that is so embedded or has become such an integral part of the materials that the legal advice cannot be redacted from them. If the legal advice is separable from the materials, then only the parts of the materials containing legal advice will be protected by privilege.

As outlined above, all employees generally have the right to know whether and what personal data is being or has been processed about them (article 8 paragraph 1, Swiss Federal Act on Data Protection; article 328b, Swiss Code of Obligations).

The employer may refuse, restrict or postpone the disclosure or inspection of internal investigation documents if a legal statute so provides, if such action is necessary because of overriding third-party interests (article 9 paragraph 1, Swiss Federal Act on Data Protection) or if the request for information is manifestly unfounded or malicious. Furthermore, a restriction is possible if overriding the self-interests of the responsible company requires such a measure and it also does not disclose the personal data to third parties. The employer or responsible party must justify its decision (article 9 paragraph 5, Swiss Federal Act on Data Protection).[1]

The scope of the disclosure of information must, therefore, be determined by carefully weighing the interests of all parties involved in the internal investigation.

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.

An employee who is a member of a works council or trade union has the right to seek assistance from the works council or trade union representative (whichever is applicable) and have the works council or trade union involved in resolving the grievances.

For unionised companies, the grievance procedure and the role of the union representative are usually set out in the collective agreement entered into between the company and the works council or trade union. In some organisations, the employee handbook or grievance policy will also state when the trade union representative will be involved in the investigation process.

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.
