Workplace Investigations

In some laws and regulations for specific industries, enterprises or personnel, there are certain requirements for the qualifications of investigators. For example, according to the Interim Measures for Investigating and Dealing with Disciplinary Violations of Professional Personnel by Medical Institutions, the personnel conducting an investigation and evidence collection shall not be less than two. If the investigator is a close relative of the investigated person, or a tip-off person or a key witness of the issue to be investigated, the investigator shall withdraw from the investigation.

However, at present, there are no unified and detailed national rules and regulations on the qualification of the investigators and organizations. In practice, the selection of the personnel and organizations responsible for internal investigation is usually based on the relevant provisions in the internal rules and regulations of the employer. The personnel conducting internal investigation are usually internal functional departments of the employer and are independent to some extent, including the personnel department, legal department, compliance department or risk control department. For significant or complex issues or senior management investigations, in order to ensure professionalism, accuracy and compliance, external law firms, consultants and accounting firms are also frequently hired to conduct investigations.

While there are no laws that set minimum qualifications for who should conduct a workplace investigation, companies often engage external legal counsel to ensure the investigation is conducted in an unbiased and professional manner. If the company itself undertakes the workplace investigation, the company should take precautions such as ensuring that the person conducting the investigation is not biased and not involved in the alleged wrongdoing. If the person conducting the investigation cannot converse in the native language of the employee under investigation, the company may consider arranging for an interpreter when conducting interviews, to minimise the risk of misunderstanding.

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.

In practice, the following factors to be considered will be: (1) verification of the informant's identity; (2) whether the informant has any conflict of interest with the reported employee or whether it will affect the objectivity of their reporting; (3) how to persuade the informant to provide more information or evidence, or to cooperate in court as a witness; (4) how to increase the admissibility of evidence when the informant refuses to cooperate in court as a witness or fails to provide original evidence; (5) how to improve the evidence chain and protect the informant from being attacked or retaliated by the informant, etc.

Aside from the legal obligations imposed on the company when dealing with a whistleblower who is subject to the WPA as discussed in question 1, there are also practical considerations the company should keep in mind when dealing with a whistleblower, regardless of whether the whistleblower falls under the WPA.

For example, there have been instances where an employee who raised allegations filed a complaint with Korean authorities (such as the Anti-Corruption and Civil Rights Commission (ACRC) or the Labour Office) that the company took retaliatory action against the whistleblower. The company should carefully review the legal risks before taking action, such as personnel action or civil or criminal action, against an employee who raises allegations if that employee was also involved in the wrongdoing.

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.
