Workplace Investigations

In internal investigations, the fundamental rights and freedoms of employees are at stake,  including the right to privacy, respect for the privacy of home life and correspondence, freedom of expression, and the obligation of loyalty in searching for evidence.

In principle, work emails and files can be reviewed, even without the employee's consent, prior knowledge or warning. This includes: work email accounts; files stored on a work computer or a USB key connected to a work computer; and SMS messages and files stored on a work mobile phone and documents stored in the workplace unless they are labelled as “personal”. On the other hand, it is not permissible for an employer (or an investigator) to review “personal” emails and files, such as documents or emails identified as “personal” by the employee, or personal email accounts (Gmail, Yahoo, etc), even if accessed from a work computer.

There are certain exceptions to the above principle. An employer is allowed to check “personal” emails or data in any of the following cases:

• if the employee is present during the review;
• if the employee is absent, but was duly notified and invited to be present;
• if there is a particularly serious “specific risk or event”;
• if the review is authorised by a judge (this means having to prove a legitimate reason justifying not informing the employee).

When documents or emails are not marked as “personal” but contain information of a personal nature, the employer may open and review the data but may not use such documents or emails to justify applying disciplinary measures to the employee or use such documents or emails as evidence in court if they indeed relate to the employee’s private life.

Special attention must be given to employee representatives who must be entirely free to carry out their duties.

As discussed in question 7, it may be difficult for a company to search an employee’s personal possessions. The company may search and gather electronic data stored in work laptops or company servers, subject to legal requirements and restrictions (eg, obtaining consent). 

The PIPA provides specific guidance on the requirements for obtaining consent. Under the PIPA, to collect or use an individual’s personal information, the information holder must be informed of and consent to:

• the purpose of the collection or use;
• the personal information that will be collected;
• the period of retention and use; and
• his or her right to refuse to provide consent and any disadvantages that may result from such refusal.

There are separate requirements for obtaining consent to provide an individual’s personal information to a third party. Also, consent must be obtained separately for the collection, use or provision of sensitive or unique identification information.

Under limited circumstances, personal information may be collected, used, or provided to third parties without obtaining the consent of the information holder. For instance, a company may collect and use personal information without obtaining consent where obtaining the information is necessary to achieve the company’s “legitimate interests”, which clearly exceed the information holder’s right to his or her personal information, and the collection and use are carried out within reasonable bounds. The term “legitimate interests” in this context is generally understood as a concept similar to “justifiable act” under the Criminal Code. The Korean Supreme Court has held that under exceptional circumstances such as the following, the company’s collection and review of employee data may constitute a “justifiable act” under the Criminal Code:

1. the company had specific and reasonable suspicion that the employee had committed a crime and the company had an urgent need to verify the facts;
2. the scope of the company’s review was limited to the suspected crime through the use of keywords, etc;
3. the employee had signed an agreement stating that he or she would not use work computers in an unauthorised manner and that all work products would belong to the company; and
4. the company’s review uncovered materials that could be used to verify whether the employee committed the alleged crime.

The basic rule is that the employer may not search private data during internal investigations.

If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

There is no obligation to share the investigation report. The findings, or a summary of them without revealing any confidential information, may be disclosed, but it is the employer’s responsibility to keep the identity of every person interviewed confidential.

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]
