Labor court dismissed dismissal for misconduct as new work norms caused minor fault, not serious breach.

The Supreme Court reversed a lower court's decision to reinstate three female workers who were terminated for alleged misconduct. The workers argued their dismissal violated labor law, while the employer claimed they breached duties by resisting new work norms. The court held that the introduction of new norms caused only minor fault, which does not justify immediate termination without notice under the Labor Code.
