Workplace 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.

No law recognises the common law concept of “attorney-client privilege” in Korea. However, communication with an attorney is protected to some extent under certain laws, such as the Constitution, the Attorney Act, the Criminal Procedure Act, and the Civil Procedure Act. This protection is based on the attorney’s confidentiality obligation, which prohibits an attorney from divulging confidential matters acquired in the course of representing clients, unless otherwise prescribed by law. This confidentiality obligation generally allows an attorney to refuse to testify or comply with document production orders for information or materials the attorney obtained in the course of his or her duties that relate to the confidential information of clients.

In addition, there could be instances where materials from an investigation conducted in Korea may become subject to discovery outside of Korea. It is, therefore, important to ensure investigation materials are privileged under the relevant non-Korean laws in the jurisdictions where attorney-client privilege is recognised (eg, the US).

As outlined above, all employees generally have the right to know whether and what personal data is being or has been processed about them (article 8 paragraph 1, Swiss Federal Act on Data Protection; article 328b, Swiss Code of Obligations).

The employer may refuse, restrict or postpone the disclosure or inspection of internal investigation documents if a legal statute so provides, if such action is necessary because of overriding third-party interests (article 9 paragraph 1, Swiss Federal Act on Data Protection) or if the request for information is manifestly unfounded or malicious. Furthermore, a restriction is possible if overriding the self-interests of the responsible company requires such a measure and it also does not disclose the personal data to third parties. The employer or responsible party must justify its decision (article 9 paragraph 5, Swiss Federal Act on Data Protection).[1]

The scope of the disclosure of information must, therefore, be determined by carefully weighing the interests of all parties involved in the internal investigation.

There is generally no obligation to report violations to the Korean authorities, subject to limited exceptions (eg, financial institutions are required to report certain types of wrongdoing to the financial regulator; if there was a leak of an industrial technology developed through a national research and development project or a national core technology, this leak should be reported to the Ministry of Trade, Industry and Energy and the National Intelligence Service). However, even in the absence of a self-reporting obligation, the company may consider strategically deciding to make a voluntary report. For example, there have been instances where the police or prosecutors’ investigations were conducted in a more limited manner where the company filed a voluntary report and cooperated with the investigation. Also, for certain types of violations (eg, cartel activities), self-reporting to the relevant authority may entitle the company to leniency provided under the law.

In certain instances, the company may also consider reporting violations to the relevant foreign authorities, in addition to, or instead of, the Korean authorities. For example, if the company found potential violations of US law such as sanctions law or the Foreign Corrupt Practice Act, the company may want to self-report these violations to the relevant authorities such as the Office of Foreign Assets Control, or the US Department of Justice.

The employer is generally not required to disclose the final report, or the data obtained in connection with the investigation. In particular, the employer is not obliged to file a criminal complaint with the police or the public prosecutor's office.

Exceptions may arise, for example, from data protection law (see question 22) or a duty to release records may arise in a subsequent state proceeding.

Data voluntarily submitted in a proceeding in connection with the internal investigation shall be considered private opinion or party assertion.[1] If the company refuses to hand over the documents upon request, coercive measures may be used under certain circumstances.[2]
