Workplace Investigations

There is no statutory rule, and therefore the investigator can be chosen by the company.

In sensitive matters, it is recommended that attorneys undertake the investigation due to legal privilege. Engaging external lawyers increases the confidence of witnesses and parties in the independence and lack of bias of the investigation process, especially when the allegations involve senior employees.

Additionally, attorneys are trained to collect information based on legal thresholds that apply to the allegations, allowing the decision-makers to understand the events as they would be posed before a labour judge or a prosecutor, and enabling them to clearly assess the legal risk involved in the situation.

As far as the persons in charge of an internal investigation are concerned, L. 4990/2022 on the protection of persons who report breaches of Union law provides for certain conditions that should be met when exercising their duties (ie, being impartial and abstaining when there is a conflict of interest), which also apply as general principles in all disciplinary procedures. Whistleblowing legislation stipulates that persons appointed to receive and investigate a whistleblowing procedure should meet certain conditions, including no penal proceedings against them, no disciplinary proceedings or convictions for specific offences, and no workplace suspensions.

Official disciplinary procedures are conducted by the competent bodies as described in the respective internal labour regulations.

Although not specifically regulated, support from external advisors (eg, lawyers) is allowed.

The examinations can be carried out internally by designated internal employees, by external specialists, or by a combination thereof. The addition of external advisors is particularly recommended if the allegations are against an employee of a high hierarchical level[1], if the allegations concerned are quite substantive and, in any case, where an increased degree of independence is sought.

There is no legal requirement or recommendation for the company to share the full or partial report or findings. It is also not a recommended measure. Therefore, unless the internal rules determine that the company must do it, any answer to queries should be limited to the fact that the investigation was concluded, and the company took the appropriate action.

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]
