Employer succession under Art. 23-1 KP binds new employer to existing collective reward rules.

The Supreme Court partially allowed the plaintiffs' claim for profit-based bonuses by overturning the lower court's decision. The plaintiffs argued that the new state agency successor was bound by the old collective reward system, while the defendant contended the calculation period was invalid. The court ruled that the new employer automatically assumed the old reward rules but correctly identified that the bonus calculation period was limited to the profitable second half of 1992.
