2. Assertion and determination

A. Articles 107 and 107 of the Civil Act (a declaration of intention which is not true) (1) of the Civil Act shall be effective even if it was known that the reporter is not a true person.

However, if the other party knew or could have known that he was not a witness, it should be null and void.

Article 4 (Establishment of Terms and Conditions of Employment) of the Labor Standards Act shall be freely established on the basis of equality, as the workers and their employer are equal.

1) The Plaintiffs asserted that the Defendant Corporation did not submit to the Plaintiffs a written resignation and a written waiver of employment experience containing each of the instant declarations of intention (hereinafter “change experience” in this case) to the Plaintiffs, “if the Defendant Corporation did not submit a written waiver of employment standard salary for new employees, the Plaintiffs need not be employed as regular employees.” Since the Defendant Corporation uniformly demanded a written waiver of employment and a written waiver of employment experience, the Plaintiffs could not make any other choice. Accordingly, each of the instant declarations of intention constitutes a declaration of intention not of intention, and thus, is null and void pursuant to Article 107 of the Civil Act or is null and void pursuant to Article 4 of the Labor Standards Act. 2) For the following reasons, the Plaintiffs’ assertion is without merit. If an employee submitted a written resignation, etc. to the employer based on his/her free will and received retirement allowances according to such a determination, it may be inevitable in accordance with the employer’s unilateral management policy to submit a written resignation, etc.
