1. Revocation of the first instance judgment.

2. The defendant shall conduct collective bargaining with the plaintiff regarding the matters for negotiations listed in the attached Table 1 list.

This Court only appealed against the judgment of the court of first instance, and only the plaintiff appealed against the judgment of the court of first instance. However, the plaintiff's claim against the defendant by the independent party intervenor is not compatible with the plaintiff's claim against the defendant, and it is necessary to make a joint decision of conclusion between the original defendant and the independent party intervenor. Thus, among the judgment of the court of first instance, the part of the plaintiff's claim against the defendant in the judgment of first instance was completely interrupted, and it is subject to

Basic facts, relevant statutes, and the grounds for the court’s explanation on this part are as stated in the “1. Basic Facts” and “2. related statutes” and “3. Party’s assertion,” respectively, and thus, they are cited in accordance with the main sentence of Article 420 of the Civil Procedure Act.

Such individual bargaining agreement of an employer is "the period for the autonomous decision of a representative bargaining trade union below the period for the autonomous decision of a representative bargaining trade union."
