Workplace Investigations

Once the decision to undertake a workplace investigation has been made, it is important to decide who is the most appropriate person to conduct the investigation. For the investigation process to run smoothly a single lead investigator should be selected, although they may work with a larger team. The lead investigator and investigation team can be internally or externally appointed.

In deciding whether to appoint an external investigator an employer should consider:

• the nature of the allegations;
• the seniority of the respondent;
• whether a fair investigation can be conducted internally without any actual or perceived bias;
• whether there is a dedicated HR department with someone who has the required capability, skills and experience to conduct the investigation; and
• whether the employer wants the investigation to be covered by legal professional privilege.

If the employer decides to investigate the matter internally without appointing a third party, then the investigator does not need to have any specific qualifications. However, it is prudent to confirm that the investigator has the time and skills to conduct the investigation and that they can be objective.   

There are no specific qualifications or requirements for an investigator. In many cases, the investigation is handled by a department or employee as deemed appropriate by the company. In some cases, an outside attorney may be asked to handle the investigation. Also, when it is a serious matter for the company, a third-party committee may be formed and commissioned to conduct an investigation.

However, under the revision of the Whistleblower Protection Act, which came into effect in June 2022, entities employing 300 or more employees must designate a person (whistleblower response service employee) in charge of accepting internal whistleblowing reports, investigating internal whistleblowing reports, or taking corrective measures as a whistleblower response service provider. Entities with less than 300 employees must also make an effort to do the same.

The person designated as a whistleblower response service provider must not divulge the name, employee ID number, or other information that would enable whistleblower identification without a justifiable reason. Criminal penalties (fines of up to 300,000 yen) have been established for violations of this confidentiality obligation.

The examinations can be carried out internally by designated internal employees, by external specialists, or by a combination thereof. The addition of external advisors is particularly recommended if the allegations are against an employee of a high hierarchical level[1], if the allegations concerned are quite substantive and, in any case, where an increased degree of independence is sought.

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.

It is possible to proceed with an investigation of a company even if there are concurrent criminal proceedings. It is up to the company to decide whether or not to proceed. The company may submit collected evidence collected to the police. The police will rarely disclose or provide the company with evidence they have collected. Usually, upon request by the police or regulator, the workplace investigation would be stayed. The police or regulator has to take legally required steps if compelling the employer to share evidence.

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).
