Workplace Investigations

If a respondent raises a grievance during the investigation this should be dealt with under any employment contract, grievance policy or industrial instrument. This may involve investigating and responding accordingly. The content of the grievance should be carefully considered, but in many circumstances it is appropriate for the initial investigation to continue. Multiple investigations can be run simultaneously.

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).

The investigator should guide the employee who has raised the grievance to properly raise their concerns through the grievance protocols or whistleblowing policy (if any). It is acceptable to preliminarily hear their concerns, but the investigation should be initiated separately and subject to the employer’s discretion.

The outcome of the investigation must be disclosed to the complainant and respondent. If there is a concurrent police or regulatory investigation, they may request a copy of the investigation report. Employers should generally cooperate with regulatory authorities, but should be careful about disclosing the investigation report as this may be privileged and privacy obligations must be considered. Employers should consider only disclosing the investigation findings and interview records if compelled to do so by regulators or police.

Interview reports, the investigation report and communications about the investigation should be kept in a separate file. The file should be marked confidential and access to the file should be restricted.

If proceedings are commenced, the investigation materials may be subject to disclosure unless legal professional privilege can be asserted, see above.

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.
