2. The parties' assertion

A. The Plaintiffs are workers under the Labor Standards Act, since they provided labor to the Defendant in subordinate relationship.

In addition, since the delegation period of this case is set, the Plaintiffs constitute fixed-term workers under Article 2 subparagraph 1 of the Act on the Protection, etc. of Fixed-Term and Part-Time Workers (hereinafter “fixed-Term Workers Act”).

However, according to Article 8 (1) of the Fixed-term Workers Act, an employer shall not give discriminatory treatment to workers who signed an employment contract with no fixed period of time engaged in the same or similar work at the workplace on the ground that they are fixed-term workers, but the defendant does not pay bonuses to the plaintiffs who are fixed-term workers, unlike those with fixed-term workers, which constitutes discriminatory treatment without reasonable grounds.

On the other hand, Article 12 subparagraph 5 of the defendant's remuneration regulation provides that bonus shall be paid to employees who have worked for not less than three months, and 300% of the base wage shall be divided into March, June, September and December.
