Workplace Investigations

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.

As discussed in question 22, when taking disciplinary action against an employee based on the outcome of an investigation, the company would need to disclose sufficient detail on the employee’s wrongdoing. However, this does not mean that the full investigation report would need to be shared with the employee to be disciplined. Key details of the investigation findings that apply to the relevant employee due to be disciplined should be shared, and not other findings concerning other persons.

There is also no requirement under Korean law for a company to disclose the investigation report or investigation findings to the whistleblower. If the company discloses the personal identity of the target employees, such disclosure could constitute a violation of the PIPA , libel or defamation under the Criminal Code. If the whistleblower strongly requests that the company share the investigation report or the findings, the company may consider providing a summary of the key findings concerning the allegations that the whistleblower raised, without disclosing personal information.

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]

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]
