Workplace Investigations

The works council does not have a general right of co-determination on whether and in what way a workplace investigation is carried out. However, workplace investigations may trigger co-determination rights of the works council in specific cases, as outlined below. If co-determination rights come into consideration, the employer must inform the works council about the investigation to put the works council in a position to assess whether or not co-determination rights are affected.

In connection with workplace investigations, the works council may have a co-determination right in the following cases:

• If e-mail accounts and data are screened by using technical devices that are suitable to monitor the behaviour or performance of employees (section 87 paragraph 1 no. 6, BetrVG).
• If, for example, the employer instructs all or a large group of employees to participate in interviews, the co-determination right of the works council regarding the rules of operation of the establishment and the conduct of employees in the establishment (section 87 paragraph 1 no. 1, BetrVG) may be affected.
• If standardised questionnaires are used in employee interviews, provided they are used for a large group of interviewed employees (section 94, BetrVG).

If co-determination rights exist in the specific case, the works council has the right to co-determine the type and structure of the specific investigative measures used (ie, the relevant investigative measure cannot be carried out without the works council's consent). To avoid any conflicts, the employer should set up, together with the works council, general rules about workplace investigations well ahead of any investigation.

Trade unions have no right of co-determination in workplace investigations.

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.

At the end of the workplace investigation, the results are presented to the company's management bodies so that they can make a decision. This may be a mere summary of the facts, or it may contain a legal assessment and recommendation for action.

There is no general obligation to report compliance violations to the police or public prosecutor's office. For some violations, there are statutory disclosure requirements. For example, data protection violations must be reported to the responsible supervisory authority (article 33 and 34, DSGVO), violations in connection with money laundering must be reported to the Central Office for Financial Transaction Investigations (section 43, Anti-Money Laundering Act), unlawful claiming of subventions must be disclosed to the subsidy-providing authority (section 3, Subventions Act), and incorrect information in the tax declaration must be reported to the tax authority (section 153, Tax Code). Additionally, in listed companies, criminal acts may constitute insider information in individual cases, and this must be disclosed within the framework of ad hoc publicity following market abuse regulations.

Also, there may be cases where reporting to the authorities should be considered for corporate policy and tactical reasons (eg, to avoid or mitigate negative consequences for the business).

Pursuant to section 17 paragraph 2, HinSchG, feedback will need to be provided to the whistleblower within three months of confirmation of receipt of the report or, if the receipt has not been confirmed to the whistleblower, within three months and seven days after receipt of the report. This includes the communication of planned and already taken follow-up measures as well as their reasons. Feedback to the whistleblower may only be provided to the extent that it does not affect the workplace investigation and does not prejudice the rights of the persons who are the subject of the report or who are named in the report.

For the question of whether internal investigations reports and material need to be shared with or can be seized by the public prosecutor, please see question 14.

In principle, there is no specific obligation for investigating persons to disclose their findings. For proceedings before a court that have been initiated or investigated by the police or competent regulatory bodies, the relevant findings may be communicated under strict conditions and provided that the personal data of the parties involved are not publicly disclosed.

More specifically, under L. 4490/2022, in the context of whistleblowing procedures, personal data and any information that leads, directly or indirectly, to the identification of the complainant are not disclosed to anyone other than employees involved in the investigation, unless the complainant consents. The identity of the complainant and any other information may only be disclosed in the context of investigations by competent authorities or judicial proceedings, to the extent necessary for the protection of the employee under investigation’s rights of defence. Confidentiality obligations govern the procedure for revealing trade secrets to police and regulatory bodies, especially in the framework of L.4990/2022.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]

The investigation findings should be disclosed to a limited group of persons who are involved in the investigation, and for which the findings are useful. For example, an HR manager who needs to record the findings in the employee’s record, the police if the employer decides to proceed further with a criminal claim, the court if requested by that court, or if there is a court case related to the violations of the employee.

Interview records should be kept confidential and private. There is a risk of disclosure because the information in the records may be beneficial to one but damaging to others. If the interview records are leaked to others who are not involved in the investigation, it may affect the work environment in the workplace and the protection of witnesses.
