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.

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]

There are no other mandatory support measures. However, an employer is free to offer additional support, for example, by granting leave from work. If tensions at the workplace are high, it may be a good idea to ask the employee under investigation to take some leave. Some companies also provide certain legal, moral or even psychological support. If the complaint concerns sexual harassment, bullying or violence at work, the prevention adviser can also recommend that the employer take additional measures to support certain employees.

Furthermore, under the whistleblower rules, an external reporting authority can grant any support measure (eg, legal advice or financial, technical, psychological or media-related, social support).

For complaints due to sexual harassment, violence or bullying at work, and if the facts are serious, the prevention adviser should, during the examination of the request and before giving his or her opinion to the employer, propose protective measures to the employer. These measures are necessary to avoid serious damage to the complainant's health or a significant deterioration in the situation (for example, causing opposing parties to commit criminal offences). The final decision on taking these measures rests with the employer. This means that the employer does not necessarily have to take the measures proposed by the prevention adviser. They may take other measures that provide an equivalent level of protection for the employee.

The employer does not generally need to provide specific support for employees that are subject to an internal investigation. The employer may, however, allow concerned employees to be accompanied by a trusted third party such as family members or friends.[1] These third parties will need to sign separate non-disclosure agreements before being involved in the internal investigation.

In addition, a company may appoint a so-called lawyer of confidence who has been approved by the employer and is thus subject to professional secrecy. This lawyer will not be involved in the internal investigation but may look after the concerned employees and give them confidential advice as well as inform them about their rights and obligations arising from the employment relationship.[2]
