Workplace Investigations

According to express provisions of L.4990/2020, in principle personal data and any other information that may lead directly or indirectly to the identification of the complainant must not be disclosed to anyone other than the investigating individuals unless the complainant gives consent[4] and that is why pseudonyms should be used. The witnesses and third persons that aid the complainant are deemed as “mediators” by the Law and their contribution to the procedure should be confidential[5].

L.4808/2021 does not indicate when such disclosures are permitted; however, it is obvious that this is a matter of cost-benefit analysis where the public interest and the fundamental rights of the involved persons should be considered in a balanced way to ensure the best results. From a data protection perspective, it could be argued that the person under investigation’s right to know the identity of the complainant, witnesses or sources of information should be limited to protect the rights of these persons.

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]

Employees under investigation frequently raise grievances during investigation procedures that are dealt with on a case-by-case basis. The grievances raised by the employee under investigation are examined by the employees responsible for the investigation. They may either pause the relevant proceedings and review the grievance, especially if the claims of the employee under investigation are linked to a breach of his or her data or hearing rights, or they may continue the investigation.

In the context of private internal investigations, grievances initially raised by the employee do not usually have an impact on the investigation.

However, if the employer terminates the employment contract due to a justified legal complaint raised by an employee, a court might consider the termination to be abusive and award the employee compensation in an amount to be determined by the court but not exceeding six months’ pay for the employee (article 336 paragraph 1 (lit. b) and article 337c paragraph 3, Swiss Code of Obligations). Furthermore, a termination by the employer may be challenged if it takes place without good cause following a complaint of discrimination by the employee to a superior or the initiation of proceedings before a conciliation board or a court by the employee (article 10, Federal Act on Gender Equality).

Under the General Data Protection Regulation, employees’ personal details and information must be kept in the business records for as long as is necessary for the purposes of the employment relationship. Otherwise, stored data must be deleted. However, under L.4990/2022[14], reports remain in the relevant record for a reasonable and necessary time, and in any case until the completion of investigations or proceedings before the courts that have been initiated as a consequence of a complaint against the employee under investigation, the complainant or any third parties.

From an employment law point of view, there is no statute of limitations on the employee's violations. Based on the specific circumstances (eg, damage incurred, type of violation, basis of trust or the position of the employee), a decision must be made as to the extent to which the outcome should remain on the record.

From a data protection point of view, only data that is in the interest of the employee (eg, to issue a reference letter) may be retained during the employment relationship. In principle, stored data must be deleted after the termination of the employment relationship. Longer retention may be justified if rights are still to be safeguarded or obligations are to be fulfilled in the future (eg, data needed regarding foreseeable legal proceedings, data required to issue a reference letter or data in relation to a non-competition clause).[1]
