Workplace Investigations

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]

Usually, a complainant submitting a grievance to the company would be a trigger for proceeding with a workplace investigation. The LPA does not specify when a workplace investigation should commence but it is subject to the employer’s work rules and regulations, including the whistleblowing policy, as the investigation usually commences after an employee or a whistle-blower has filed a complaint to the employer. In some cases, there might be a whistleblower and the start of the workplace investigation would be subject to the whistleblowing policy and the employer’s discretion. Also, if a questionable transaction or activity is detected, fiscal audits may be the source that triggers a voluntary workplace 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.

Thai labor laws do not require a workplace investigation to involve participation from trade unions or labour unions. However, it is possible for labour unions established under the Labor Relation Act BE. 2518 (1975) to submit a demand for a collective bargaining agreement (CBA) with employers to get a seat at the table. There was a case where a management union made a CBA with the employer wherein the president of the management union would be involved in any investigation of any manager, who is a union member, under investigation. In that case, the employer must comply with the CBA by informing the president and allowing the president to participate in the investigations.
