G.R. No. L-51544. August 30, 1990. CONTINENTAL CEMENT CORPORATION LABOR UNION (NLU), petitioner, vs. CONTINENTAL CEMENT CORPORATION and the DEPUTY MINISTER OF LABOR, respondents.
FACTS

The dispute originated from disagreements over the implementation of a 1975 NLRC arbitration award concerning vacation, sick leaves, and wage standardization. After a series of strikes and settlements over delayed payments, a new issue arose regarding the payment of leave benefits for the period July 1975 to June 1976. The union initially agreed to a staggered payment but later issued an ultimatum for immediate payment. When the company requested a brief extension, the union staged a strike on July 12, 1976, with its officers and members manning picket lines. The Minister of Labor issued a return-to-work order on July 13, 1976, which was served that afternoon. Compliance was minimal, with only 11 out of about 120 workers in one shift reporting on July 14. The union filed a motion for reconsideration and continued picketing. On July 23, 1976, the Minister certified the dispute to the NLRC for compulsory arbitration, which under the Labor Code automatically enjoined any strike. Despite this, approximately 110 striking workers refused to return to work.

ISSUE

Whether the National Labor Relations Commission and the Deputy Minister of Labor committed grave abuse of discretion in ordering the dismissal of the union officers and the suspension of the striking members.

RULING

The Supreme Court ruled that there was no grave abuse of discretion. The strike staged on July 12, 1976, was illegal from its inception because it was based on a non-strikeable issue—the interpretation and implementation of a prior arbitration award, which should have been resolved through the grievance machinery or arbitration. More critically, the striking workers repeatedly defied lawful orders from the Director of Labor Relations and the Minister of Labor to return to work, first under the July 13 return-to-work order and later after the July 23 certification order which carried an automatic strike injunction. The defiance of these orders constituted a serious violation of the Labor Code, particularly as the cement industry was considered vital. The NLRC’s differentiation in penalties was legally sound. The union officers, who have a statutory duty under Article 242 (now 241) of the Labor Code to guide their members and inform them of labor laws, bore greater responsibility. They misled the members into undertaking and persisting in an illegal strike. Their dismissal was a just penalty for these unlawful acts. For the ordinary members, the NLRC exercised compassion by imposing only suspension for the duration of their absence instead of dismissal, which the labor arbiter had initially recommended. The Court found the penalties appropriate to uphold the state’s interest in maintaining industrial peace, especially in vital industries, and to sanction labor leaders who fail in their fiduciary duties.
