Workplace Investigations

Since inspections of personal belongings may potentially undermine employees' fundamental human rights, they would not become lawful simply because they are conducted under employment regulations.

Inspections of personal belongings must be conducted uniformly among employees in the workplace based on reasonable grounds, in a generally reasonable manner and to a generally reasonable degree, and based on the work rules, etc.

When inspections of personal belongings are conducted under employment regulations, etc, employees must agree to the inspection except in special circumstances, such as the method or degree of the inspection being unreasonable.

On the other hand, an investigation of information stored on a company network system may constitute an infringement of the right to privacy. If there is a provision in the employment regulations regarding the use of the internet and monitoring, it is possible to investigate under such a provision. A Japanese court case on the illegality of reading e-mails in the absence of a monitoring provision stated that private use of e-mails also carries a certain right to privacy, but also stated that "considering the fact that the system is maintained and managed by the company, the protection of the employee's privacy can only be expected within a reasonable range according to the specific circumstances of the system," and that the act of reading e-mails was not illegal because the extent of private use of e-mails was beyond the limit, which was outside the reasonable range of socially accepted ideas. The court also ruled that the monitoring of the employee's abusive private use of e-mail, which was discovered in the course of an investigation of slanderous e-mails within the company, was not illegal because even if the monitoring was conducted without notice, there was suspicion of a violation of the duty of devotion to duty and corporate order. The court also stated that the investigation was necessary and that the scope of the investigation did not exceed its limit.

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]
