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.

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.

L.4990/2022 explicitly states that the exercise of employee rights that refer to consulting from representatives or trade unions and protection against any detrimental measure that results from those consultations does not affect the implementation of any legal provisions. The autonomy of social partners and their right to enter into collective agreements regardless of the level of protection provided by L.4990/2022[7] is also unaffected.

Under L.4808/2021, legal persons and associations of persons, including trade unions, that have a legitimate interest in doing so may, with the consent of the complainant, bring an action in the complainant’s name before the competent administrative or judicial authorities. They may also intervene in their defence[8].

In general, works councils and trade unions are not very common in Switzerland and there are no statutory rules that would provide a works council or trade union a right to be informed or involved in an ongoing internal investigation. However, respective obligations might be foreseen in an applicable collective bargaining agreement, internal regulations or similar.

In principle, the health of an ordinary employee would not prevent the investigation procedure from taking place (eg, interviews with witnesses or the collection of evidence would not be postponed or suspended). However, if the employee under investigation is unwell and they can't participate in the procedure, the investigation may be suspended or postponed until the employee can take part. Bearing in mind the majority of company internal policies and regulations governing workplace investigations provide for a specific framework and timetable for the whole procedure to be completed, the long-term sickness of an employee under investigation may impede the completion of the procedure in the prescribed time. As a result, the person conducting the investigation may seek alternative measures to facilitate participation (eg, teleconferencing).

On a related note, if sickness occurs after the investigation is completed and the employer decides upon the imposition of disciplinary measures against the said employee and the initiation of a relevant procedure, the decision should be duly and timely communicated to the employee, irrespective of whether his or her presence in the workplace is not possible because of the illness.

The time spent on the internal investigation by the employee should be counted as working time[1]. The general statutory and internal company principles on sick leave apply. Sick leave for which the respective employee is not responsible must generally be compensated (article 324a paragraph 1 and article 324b, Swiss Code of Obligations). During certain periods of sick leave (blocking period), the employer may not ordinarily terminate the employment contract; however, immediate termination for cause remains possible.

The duration of the blocking period depends on the employee's seniority, amounting to 30 days in the employee's first year of service, 90 days in the employee's second to ninth year of service and 180 days thereafter (article 336c paragraph 1 (lit. c), Swiss Code of Obligations).
