Workplace Investigations

Before commencing a workplace investigation, an employer must review the terms of any applicable employment contract, policy, procedure or industrial instrument. These documents will likely contain clauses that will dictate the investigation process.

There is also a significant body of common law that dictates how an investigation should be conducted and the procedural fairness that should be afforded to those involved. To ensure a workplace investigation is procedurally fair, employers must consider several factors, including:

• putting all allegations to the respondent in a manner which does not suggest a pre-determination of the outcome;
• conducting the investigation in a timely manner;
• providing the respondent with the opportunity to respond to the allegations;
• conducting a fair investigation process;
• making an unbiased (and not pre-determined) decision; and
• permitting the respondent and complainant to involve a support person or union representative.

Employers should also consider the additional steps they can take to conduct a best-practice investigation, including:

• being thorough and taking the time to plan the investigation;
• communicating clearly and fairly;
• considering whether the allegations are indicative of a wider workplace behaviour problem;
• maintaining confidentiality; and
• preventing victimisation.

There is no specific legal regulation for internal investigations in Switzerland. The legal framework is derived from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights. Depending on the context of the investigation, additional legal provisions may apply; for instance, additional provisions of the Swiss Federal Act on Data Protection or the Swiss Criminal Code.

The investigator should prepare a written report setting out whether the allegations are substantiated, unsubstantiated or cannot be determined due to insufficient evidence. This report should be used for internal purposes only. Accordingly, the report should not be shared with the complainant, respondent or witnesses unless required by law, the employer’s policies or another industrial instrument. It is particularly important not to share the investigation report should the employer wish to maintain privilege in respect of the report.

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]
