Workplace Investigations

Regarding L.4990/2022 for whistleblowers’ procedures, many categories of privilege may occur during an investigation, such as: attorney-client privilege; doctor-patient privilege; and court or other proceedings’ privilege deemed as classified. L.4990/2022 provides that its provisions do not affect any of these privileges and these privileges supersede[6].

Privilege may also be attached to investigation materials in investigations relating to workplace harassment and violence incidents; however, since L.4808/2021 does not offer a specific provision and criminal proceedings may also commence, the matter of privilege must be examined ad hoc.

Professional advice given by an "advocate" to a client is protected as “privileged communication” and is not admissible as evidence in a court of law. Such privilege may not attach to advice or communications involving in-house lawyers as they are not licensed advocates (since they are expected to surrender their bar licences when they take on in-house roles). This is a grey area as there are conflicting judicial precedents on this. Hence, communications, documents or information gathered during an investigation conducted entirely internally may not be legally privileged and may be discoverable in a dispute. That said, companies generally mark sensitive communications with in-house attorneys as privileged and confidential in an attempt to protect the same.

For the above reasons, investigations conducted by external advocates have better chances of retaining legal privilege. However, the following will not be treated as privileged information:

• any correspondence about the commission of a crime or fraud by the client; and
• the observations of an attorney that would suggest that a crime or fraud will be committed by the client.

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.

If any unrelated matters are revealed as a result of an investigation and are of legal importance, the applicable legal provisions must be implemented and any relevant policies or agreements between the involved parties should be taken into account. For example, if the reporting procedure sheds light on other criminal acts, criminal law procedure may be followed if the matter is reported to the competent authorities.

If these unrelated matters fall under the ambit of another company’s policies, the relevant procedures may also be followed separately. However, the employee under investigation must be allowed to defend him or herself, otherwise he or she may raise complaints relating to the procedural guarantees of the investigation.

Where unrelated matters are revealed during, or because of, the investigation, the course to be adopted may depend on several factors. Normally, if additional instances of misconduct are revealed against the same accused employee, even if they are unrelated to the original investigation, it would be advisable to independently investigate those issues too, to ensure that there are comprehensive grounds for any future disciplinary inquiry or action. If unrelated matters are revealed against other stakeholders involved in the investigation – for example, a forensic review reveals that the complainant or some witnesses have themselves potentially engaged in some other form of policy breach – whether or not those issues are investigated (as well as the timing of such investigation) would need to be decided on a case-by-case basis. Issues to consider include whether these matters affect the credibility of their statements, point at some form of other conspiracy, or create the risk of retaliation claims at a later date.

In SH matters, however, if the complaint involves instances of sexual harassment as well as other forms of general harassment or misconduct, to the extent such other issues aren't linked to the instances of sexual harassment (eg, creation of a hostile work environment for the complainant), these other concerns should preferably not be investigated by the IC and instead should be referred to the employer to address, as per its general grievance-redressal mechanisms.

There are no regulations in this regard in the Swiss employment law framework. However, in criminal proceedings, the rules regarding accidental findings apply (eg, article 243, Swiss Criminal Procedure Code for searches and examinations or article 278, Swiss Criminal Procedure Code for surveillance of post and telecommunications). In principle, accidental findings are usable, with the caveat of general prohibitions on the use of evidence.
