2. The assertion and judgment

A. The summary of the Plaintiff’s assertion 1) Article 25(1) of the Defendant’s collective agreement provides that “when a company approves a member of his/her retirement, the company shall submit a letter of resignation and which shall take effect upon the company’s approval (approval).” The Plaintiff may freely withdraw his/her intent of retirement before the Defendant approves the Plaintiff’s retirement pursuant to Article 25 of the collective agreement. (2) As to the implementation of a voluntary retirement on November 29, 2017, the Defendant publicly announced that “the procedure for retirement: the scheduled date of approval for a voluntary retirement after the individual examination for the application for a voluntary retirement, and the application document: A voluntary retirement application form (a separate draft, such as a letter of resignation and a written pledge)” under Article 25(1) of the said collective agreement is the same as “written resignation” under the language and text, and thus, the effect of retirement takes effect only when the Plaintiff separately submits a written resignation.

3. However, on March 15, 2018, the Plaintiff did not submit a written resignation separately, and on March 15, 2018, before the voluntary retirement takes effect.
