Workplace Investigations

There are no legal requirements in this respect – it depends on the internal policies or practices at a given working establishment. Based on our experience – an internal investigation usually commences with a preliminary assessment of a reported irregularity. If the preliminary assessment leads to a conclusion that a reported situation may be an irregularity, an investigation is launched by appointing a commission or team that conducts the investigation or selecting an investigator. Then, a plan of investigation is established. Depending on the circumstances, the investigation plan may involve a collection of documents or files, their analysis, and interviews with a victim, witnesses or a subject (although the procedure depends on the type of case, internal rules and practice). At the end of the process, the report is prepared by the commission or team with facts established during the process, recommendations, and other suggestions as to the investigated issue.

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

The trigger could come from several sources, such as a grievance from a current or former employee, a complaint from external sources, a whistleblowing disclosure, or as the result of internal governance measures.

In each case, the employer will need to decide if an investigation is warranted. It may be required by internal policies or regulatory requirements in some circumstances. Consideration must be given to whether an investigation is feasible; for example, is the evidence still in existence and accessible? Are key witnesses still employed or contactable?

If the employer concludes that an investigation is warranted, it should start without unreasonable delay. The first step would usually be to set terms of reference, which outline the purpose and remit of the investigation. These should be closely drafted and continually referred to, to avoid the investigation’s scope expanding when new points arise (as they almost always will). An investigator will also need to be appointed (see question 4).

In principle, an internal investigation should be conducted in the same way, regardless of whether it is initiated following a whistleblowing report, an audit, or a monitoring result. This includes anything related to confidentiality, fairness, data privacy protection, etc.

If an internal investigation is initiated following a whistleblower report, the main characteristic that is imposed by the EU Directive on the protection of persons who report breaches of EU Law (Whistleblowers Directive) and that will also be available under the Draft Law is for the organisation (employer) to communicate (if practicable) the report to the whistleblower. Furthermore, the whistleblower should receive feedback as to whether follow-up actions were undertaken following the report and, if yes – what actions were taken – and if not – why the follow-up actions were not taken.

If an employee complains to his or her superiors about grievances or misconduct in the workplace and is subsequently dismissed, this may constitute an unlawful termination (article 336, Swiss Code of Obligations). However, the prerequisite for this is that the employee behaves in good faith, which is not the case if he or she is (partly) responsible for the grievance.

The employer should first identify which individuals may have protection as whistleblowers. This could be a current or former employee who raises the initial complaint, a co-worker who gives evidence as part of the investigation, or the accused employee.

In each case, consider whether a “protected disclosure” has been made (under Part IVA ERA 1996). This requires analysis of the subject matter of the disclosure, how it is made, and a reasonable belief that it is made in the public interest.

Employers must then ensure there is no detrimental treatment or dismissal of any worker on the grounds of their protected disclosure. Although the causation test for these purposes is not straightforward, as a general rule if the protected disclosure has a “material influence” on the decision to discipline or dismiss, there may be liability. Individual managers may be personally liable alongside the employer. Compensation for whistleblowing cases is uncapped, meaning businesses and individuals can face significant financial and reputational exposure.

What this means in practical terms is that the employer should promote a “speak-up” culture and, where protected disclosures are made, ensure they are handled by a team who are properly trained in how to do so.
