Civil service work condition changes without consent are invalid under Labor Code Art. 42 and Union Law Art. 32.

The Supreme Court dismissed the cassation appeal regarding a civil servant's claim that a change in work conditions was invalid. The plaintiff argued that the employer unilaterally transferred him to a role requiring different professional knowledge without his consent, constituting an unfavorable change under Labor Code Art. 42. The court held that such a change requires employee consent or must be treated as a termination under specific union protection rules, rendering the unilateral action ineffective.
