Workplace Investigations

According to L.4990/2022, any form of retaliation against complainants is prohibited, including threats of retaliation[9]. The complainants have the right to cost-free legal advice about possible acts of retaliation as well as cost-free provision of psychological support (to be defined by Ministerial Decisions)[10]. In terms of other types of support, the complainants are not in principle liable for the acquisition of information or releasing the information they reported under specific conditions (eg, the acquisition or access does not independently constitute a criminal offence, if they had reasonable grounds for believing that a report was necessary to reveal the violation)[11].

L. 4808/2021 states that the dismissal or termination of the legal relationship of employment and any other discrimination that constitutes an act of revenge or retaliation is prohibited and invalid[12].

The employer does not generally need to provide specific support for employees that are subject to an internal investigation. The employer may, however, allow concerned employees to be accompanied by a trusted third party such as family members or friends.[1] These third parties will need to sign separate non-disclosure agreements before being involved in the internal investigation.

In addition, a company may appoint a so-called lawyer of confidence who has been approved by the employer and is thus subject to professional secrecy. This lawyer will not be involved in the internal investigation but may look after the concerned employees and give them confidential advice as well as inform them about their rights and obligations arising from the employment relationship.[2]

There is no explicit legal provision stating the whole report must be communicated with the employee under investigation. The legal framework (L.4990/2022 and L.4808/2021) is governed by strict confidentiality obligations and obligations to protect the complainant’s data. From a data protection regulation perspective, it could be argued that the right of the person under investigation to know the identity of the complainant, witnesses or sources of information should be limited to protect the rights of such persons.

However, if the outcome of the investigation leads to the imposition of disciplinary measures, the right of the employee under investigation to request the whole investigation report, to aid in their defence is enhanced. Moreover, if a complaint is made in bad faith or is unfounded, it may be supported that the employee under investigation is entitled to receive full documentation so he or she can seek adequate legal protection or file an action before the courts.

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]

In principle, there is no specific obligation for investigating persons to disclose their findings. For proceedings before a court that have been initiated or investigated by the police or competent regulatory bodies, the relevant findings may be communicated under strict conditions and provided that the personal data of the parties involved are not publicly disclosed.

More specifically, under L. 4490/2022, in the context of whistleblowing procedures, personal data and any information that leads, directly or indirectly, to the identification of the complainant are not disclosed to anyone other than employees involved in the investigation, unless the complainant consents. The identity of the complainant and any other information may only be disclosed in the context of investigations by competent authorities or judicial proceedings, to the extent necessary for the protection of the employee under investigation’s rights of defence. Confidentiality obligations govern the procedure for revealing trade secrets to police and regulatory bodies, especially in the framework of L.4990/2022.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]
