Workplace Investigations

From an Italian employment law perspective, there is no specific body of legislation that governs investigations. However, several legal and case-law principles may be relevant concerning various specific aspects of investigations, and to which reference will be made below (eg, provisions under Law No. 300 of 1970, the so-called Workers’ Statute regarding “controls on employees”, both physical and “remote”, or regarding “disciplinary proceedings”).

In addition, and outside of the specific scope of employment law, other law provisions may have an impact on investigations, including those regarding privacy law (eg, Italian Legislative Decree No. 196 of 2003 and the Regulation (EU) No. 679 of 2016 (GDPR), regarding data protection and the related policies), whistleblowing (Law No. 179 of 2017 and Directive (EU) No. 1937 of 2019, regarding whistleblower protection) and criminal law (eg, Italian Criminal Procedure Code, providing rules for criminal investigation and Italian Legislative Decree No. 231 of 2001, regarding the corporate (criminal) liability of legal entities).

There is no specific legal regulation for internal investigations in Switzerland. The legal framework is derived from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights. Depending on the context of the investigation, additional legal provisions may apply; for instance, additional provisions of the Swiss Federal Act on Data Protection or the Swiss Criminal Code.

Yes, in principle the identity of the complainant, witnesses or sources of information for the investigation can be kept confidential.

On the other hand, if the employer – after having concluded the investigation – brings disciplinary action against the employee, the employer must send a letter to the employee in which the facts are described in detail, objectively and in a precise way, identifying when and where they have taken place, to allow a proper defence for the employee.

Even at this stage, however, the employer has no obligation to provide the employee with the evidence underlying the facts ascribed to him (ie, the employer has no obligation to specify the identity of the individuals through which they gained knowledge of the facts reported in the disciplinary letter).

However, if the employee subsequently challenges the disciplinary sanction before a judge, the employer bears the burden of proof, which may mean having to call the individuals interviewed within the internal investigation to stand as witnesses in court.

Moreover, in case of whistleblowing reports falling within the scope of the WB Decree, the employer is requested to generally keep the whistleblower’s identity confidential (according to art. 12 of the WB Decree). More specifically: (i) if the disciplinary charges are grounded on investigations which are different and additional to the whistleblowing report (although arising as a consequence of the report), the whistleblower’s identity may not be disclosed; (ii) if the disciplinary charges are grounded, in whole or in part, on the whistleblowing report, and knowing the identity of the whistleblower is indispensable for the defendant, such report may be used for the purpose of the disciplinary proceeding only if the whistleblower gives consent to his/her identity being revealed.

As mentioned under Question 10, the employer’s duty of care (article 328, Swiss Code of Obligations) also entails the employer’s duty to respect and protect the personality (including confidentiality and privacy) and integrity of employees (article 328 paragraph 1, Swiss Code of Obligations) and to take appropriate measures to protect them.

However, in combination with the right to be heard and the right to be informed regarding an investigation, the accused also has the right that incriminating evidence is presented to them throughout the investigation and that they can comment on it. For instance, this right includes disclosure of the persons accusing them and their concrete statements. Anonymisation or redaction of such statements is permissible if the interests of the persons incriminating the accused or the interests of the employer override the accused’ interests to be presented with the relevant documents or statements (see question 11; see also article 9 paragraphs 1 and 4, Swiss Federal Act on Data Protection). However, a careful assessment of interests is required, and these must be limited to what is necessary. In principle, a person accusing another person must take responsibility for their information and accept criticism from the person implicated by the information provided.[1]
