Workplace Investigations

Investigation materials are not privileged and an employer may be required to disclose them in subsequent legal proceedings. If an employer is concerned about privilege attaching to an investigation, they should engage a legal practitioner to facilitate the investigation.

Employers who are concerned about privilege attaching to investigation materials should also consider the method of a lawyer’s engagement. The lawyer should be expressly engaged to investigate, report and to assist the employer by providing legal advice. Additional benefits can be achieved if the legal practitioner engages an external investigator to investigate the complaint and prepare the investigation report. Privilege will attach to the investigation materials because they are prepared for the lawyer to allow the lawyer to provide legal advice to the employer.

It is important that employers do not expressly or inadvertently waive privilege. For example, by disclosing the investigation report or substantial contents of the investigation report. It is a balance between providing information to the respondent and complainant about the outcome of the investigation and disclosing too much information.

In general, from an employment law perspective, workplace investigations made by corporate departments (eg, HR and legal counsel who do not operate in their function as lawyers) are not covered by privilege. Generally speaking, privilege covers correspondence and conversations between lawyers.

In defensive criminal law investigations, legal privilege applies.

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.

A trade union does not have any right to be informed of, or involved in, an investigation by an employer. However, an employee may request that their support person is a trade union member or trade union representative. This is appropriate and should be permitted.

Employers should review the terms of an employment contract, policy or industrial instrument as this may contain terms regarding trade union involvement. In particular, heavily-unionised workplaces may contain enterprise agreements which contain relevant clauses.

Generally speaking, a workplace investigation does not require the involvement of a trade union (on the assumption that no specific union agreement has been reached at a company level to entitle trade unions to specific forms of consultation or involvement in workplace investigations, which is not common).

According to section 4 of the Workers’ Statute, as stated above, the involvement of the trade union is necessary regarding the installation and use of specific equipment (such as cameras, switchboards, software) that potentially allows the employer to remotely monitor working activity, and which can be done only with prior agreement of the unions (or authorised by the labour inspectorate).  The union agreement must be made before the installation of the system, and therefore would normally be already in place when an investigation starts.

Pursuant to the WB Decree (Art. 4), union representatives (or external unions) should be “heard” before the employer activates a WB reporting channel[1].

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.
