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.

There are circumstances of misconduct in the workplace that can also constitute criminal conduct and be subject to a criminal or regulatory investigation. This can include physical or sexual assault, theft, fraud, illegal drug use or stalking.

An employer can proceed with an investigation to determine whether the respondent engaged in misconduct on the balance of probabilities. The employer can terminate an employee’s employment before the outcome of any criminal investigation. However, the employer must keep in mind that procedural fairness must be afforded to the employee, particularly in circumstances where an employee is awaiting the outcome of a court proceeding.  

Alternatively, an employer may decide to suspend the employee pending the outcome of the criminal investigation. If a criminal act has been committed, then the employer may decide to terminate the employee’s employment.

Co-operation with the police and regulatory authorities is sensible and evidence can be compelled by the police or regulators by, for example, a subpoena, search warrant or an order for production.

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).
