Workplace Investigations

If the complainant made use of an internal whistleblowing procedure, confidentiality regarding the identity of a reporter is mandatory. Also, in other cases and for other involved persons (witnesses), it is recommended to keep their identity confidential to prevent the risk of intimidation or other negative consequences.

In complaints due to sexual harassment, violence or bullying at work, if the prevention adviser heard or took written statements from persons that were considered useful for the evaluation, these persons may remain anonymous.

The employee must, nevertheless, receive sufficient information to be able to offer a defence concerning the facts of which he or she is accused.

The response and approach to this would be very fact-specific.

Under the SH Act, an individual cannot file an anonymous complaint and, therefore, the name of the complainant cannot be kept confidential. The same would go for details of witnesses, if any.

For other types of misconduct, the name of the complainant could potentially be kept confidential, depending on the nature of the allegations. For example, if an individual observes another colleague or employee committing inappropriate conduct (such as fraud or bribery) and reports this, the name of the complainant may not necessarily have to be disclosed to the accused employee, especially where the company is independently able to gather evidence substantiating the allegations. The names of witnesses generally cannot be kept confidential, since doing so may prove prejudicial to the accused employee. Further, as part of the disciplinary inquiry process, the accused has the right to cross-examine witnesses.

Notwithstanding the above, the approach to this issue should be assessed on a case-by-case basis by looking at the underlying sensitivities and risks involved. Courts have, in limited circumstances, permitted non-disclosure of the names of witnesses or complainants.

As in question 10, the identity of the complainant or other employees involved in the investigation may be kept confidential and companies do not have to share their identity with investigated employees. Anonymous complaints are expressly allowed under Spanish law (see question 9).

Companies may have to produce this information and share it with the investigated employees if it is necessary to allow them to defend themselves from disciplinary measures taken against them. Similarly, in the context of litigation, an employee or plaintiff could request a Labour Court to order the company to disclose the details of the investigation.

As mentioned under Question 10, the employer’s duty of care (article 328, Swiss Code of Obligations) also entails the employer’s duty to respect and protect the personality (including confidentiality and privacy) and integrity of employees (article 328 paragraph 1, Swiss Code of Obligations) and to take appropriate measures to protect them.

However, in combination with the right to be heard and the right to be informed regarding an investigation, the accused also has the right that incriminating evidence is presented to them throughout the investigation and that they can comment on it. For instance, this right includes disclosure of the persons accusing them and their concrete statements. Anonymisation or redaction of such statements is permissible if the interests of the persons incriminating the accused or the interests of the employer override the accused’ interests to be presented with the relevant documents or statements (see question 11; see also article 9 paragraphs 1 and 4, Swiss Federal Act on Data Protection). However, a careful assessment of interests is required, and these must be limited to what is necessary. In principle, a person accusing another person must take responsibility for their information and accept criticism from the person implicated by the information provided.[1]
