G.R. No. 160828; August 9, 2010
PICOP RESOURCES, INCORPORATED (PRI), Petitioner, vs. ANACLETO L. TAÑECA, ET AL., and NAMAPRI-SPFL, Respondents.

FACTS

Respondents were regular rank-and-file employees of petitioner PICOP Resources, Inc. (PRI) and members of the exclusive bargaining agent, NAMAPRI-SPFL. The operative Collective Bargaining Agreement (CBA) contained a union security clause requiring employees to maintain union membership in good standing as a condition of employment. In May 2000, before the CBA’s expiry, the union demanded PRI terminate several members, including respondents, for alleged acts of disloyalty. The specific act was campaigning for and signing a petition for a certification election for a rival union, the Federation of Free Workers (FFW), during the CBA’s lifetime. After requiring explanations, PRI terminated the employees based on the union’s finding of disloyalty and the CBA’s union security clause.
The terminated employees filed a complaint for illegal dismissal and unfair labor practice. The Labor Arbiter ruled the dismissals were illegal, finding the act of supporting a rival union was not among the grounds for termination under the CBA’s maintenance of membership clause, which only covered voluntary resignation or non-payment of dues. The National Labor Relations Commission (NLRC) reversed, upholding the dismissals. The Court of Appeals reinstated the Labor Arbiter’s decision, prompting PRI’s appeal to the Supreme Court.

ISSUE

Whether the employees’ act of supporting a rival union during the term of the CBA constitutes a valid ground for dismissal under the union security clause.

RULING

No. The Supreme Court denied the petition and affirmed the Court of Appeals. The legal logic centers on a strict interpretation of the union security clause and the nature of the employees’ act. The specific CBA provision required employees to “maintain their membership in the UNION in good standing.” The Court ruled that “membership in good standing” is traditionally defined by the union’s constitution and bylaws, and loss of good standing typically occurs only for two reasons: voluntary resignation or non-payment of regular union dues. The act of signing a petition for a certification election for a rival union, while arguably an act of disloyalty, does not automatically equate to a failure to maintain membership or a loss of good standing as contractually defined.
Crucially, the employees never formally resigned from NAMAPRI-SPFL nor ceased paying dues. Their internal support for a rival union is a protected activity related to their right to self-organization, which cannot be penalized by dismissal under the guise of a union security clause. The Court emphasized that union security clauses are strictly construed, and dismissal thereunder is a severe penalty that must be based on clear contractual grounds. Since the CBA did not explicitly define supporting a rival union as a ground for loss of good standing or termination, PRI acted without just cause in effecting the dismissals. The termination was therefore illegal.
