Workplace Investigations

In general, an internal investigation is only initiated if there is suspicion of a violation. The decision to commence an internal investigation is up to the company, and it has to weigh the pros and cons. For limited liability companies, which are subject to the Association Responsibility Act, an internal investigation may exempt them from criminal liability. Disadvantages may include investigation costs, disruption of operations, discovery of information requiring later disclosure, possible negative media coverage and increased risk of exposure to external parties.

Investigations can relate to specific individuals, departments, or the entire company. An investigation may include various measures, such as obtaining and analysing files and documents, conducting questionnaires and employee interviews, monitoring internet use, video or telephone surveillance of employees and setting up whistleblowing hotlines. Not all measures are acceptable without restrictions. The provisions of labour law and data protection law must always be complied with.

To avoid wasting resources, the objectives of the investigation should be defined in advance. In addition, the selection and sequence of instruments to be used should be determined. A legal assessment of the chosen measures is essential to avoid legal complications.

Internal investigations can be initiated either upon a complaint or report by an employee, (or other persons providing services or seeking employment, etc) in the workplace or by the employer as part of their managerial right.

If from an employee, the complaint or report may fall within the scope of an internal disciplinary procedure, if any, or may concern an alleged workplace violence or harassment incident, or fall within the scope of L.4990/2022 on the protection of persons who report breaches of Union law.  

Reports by whistleblowers are submitted to the manager with responsibility for receiving and monitoring reports, a person appointed for that purpose under L.4990/2022. Complaints for incidents and harassment in the workplace can also be submitted, according to L.4808/2022, to the person or internal body specifically assigned to receive such complaints. Both laws require the employer to define the persons competent for receiving and monitoring complaints or reports and notifying the employees stricto sensu and any other persons falling within the scope of the respective provisions.

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

If a lawyer is involved in the investigation, communication between the lawyer and client is subject to legal professional privilege. These communications must not be disclosed. Any documents collected by an internal audit can be seized and used. However, a document created by a lawyer can only be seized. The same applies to other professional representatives of parties, such as notaries and auditors, as potential holders of professional secrecy.

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.
