Workplace Investigations

Employers will generally take steps to treat complaints sensitively and confidentially. However, because of the obligations employers have, confidentiality cannot be guaranteed as part of the investigation and the complainant, respondent and witnesses should be made aware of this.

Understandably, the complainant or witnesses may wish to remain anonymous. However, because the details of the allegations need to be put to the respondent so that they can provide an informed response or explanation, the source of the information will often need to be disclosed.  

Employers can take steps to “ringfence” the investigation by asking employees to sign a confidentiality agreement. This will protect the interests of the participants of the investigation and uphold the integrity 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]

It is possible to keep such information confidential. If this is the case, the investigation team should conduct the interview outside the workplace of the company. This is actually good practice applicable to all internal investigations, unless there is a particular reason that requires the meetings to be held at the company.

Employers must take steps to deal with the findings of the investigation and implement any recommendations promptly. This may involve commencing disciplinary action.

The complainant and respondent need to be informed of the outcome of the investigation. All witnesses who participated in the investigation should also be thanked for their contribution and advised that the investigation has been completed. All participants in an investigation should be reminded of their ongoing obligations concerning confidentiality and victimisation.

If an employer decides that it may be appropriate to terminate a respondent’s employment, the employee must be provided with the opportunity to respond and to “show cause” as to why their employment should not be terminated.

The investigation report along with any other materials produced during the investigation should be kept in a separate confidential file.

Employers should also consider whether action should be taken at an organisational level to prevent future misconduct. In particular, employers are required to take a proactive approach to addressing systemic workplace cultural issues in relation to sex discrimination, sexual harassment and victimisation.

If the investigation uncovers misconduct, the question arises as to what steps should be taken. Of course, the severity of the misconduct and the damage caused play a significant role. Furthermore, it must be noted that the cooperation of the employee concerned may be of decisive importance for the outcome of the investigation. The possibilities are numerous, ranging, for example, from preventive measures to criminal complaints.[1]

If individual disciplinary actions are necessary, these may range from warnings to ordinary or immediate termination of employment.

The employer may take various legal remedies against the employee whose infringement is discovered as a result of the internal investigation. Depending on the outcome of the investigation, the employer:

• may provide the employee with a written warning requesting him or her not to repeat the same conduct;
• terminate the employment relationship based on either just cause, without paying any compensation immediately, or valid reason by observing statutory notice periods or making payment in lieu of notice and paying severance compensation if applicable; or
• not take any action if the investigation concludes that no fault is attributable to the employee.
