Labor dispute where a collective agreement change was dismissed as it lacked statutory termination procedures.

The Supreme Court dismissed the plaintiff's claim for unpaid wages based on a collective agreement change. The plaintiff argued that the employer failed to follow proper termination procedures under the Labor Code, while the employer contended that the changes were accepted through informal correspondence. The court ruled that since the wage adjustments were beneficial and accepted by the employee without objection, they constituted valid agreements rather than unilateral changes requiring formal termination.
