2. The summary of the Plaintiff’s assertion is the deceased’s employer, and even though the Plaintiff, who works in the area where the punishment is concentrated, has a duty to prevent damage to the harmful insects, such as punishment, was negligent in doing so, and thus, the deceased caused the instant accident to be compensated for the damage therefrom.

3. As an incidental duty under the good faith principle accompanying a labor contract, an employer bears the duty to take necessary measures, such as improving human and physical environment, so that an employee does not harm life, body, or health, while providing labor. In the event that an employee suffers damage by violating such duty of protection, the relevant employer is liable for compensating for damages (see, e.g., Supreme Court Decisions 9Da47129, May 16, 200; 97Da12082, Feb. 23, 199). However, barring any special circumstance, the accident is not only related to the employee’s work, and it is anticipated that the accident is ordinarily likely to occur.
