When Union Disaffiliation Leads to Dismissal: Union Security Clauses and Illegal Strikes

The Supreme Court clarifies who may enforce a union security clause and when a strike becomes illegal, affecting dismissal of union officers and members.


The Supreme Court's 2017 decision in Ergonomic Systems Philippines, Inc. v. Enaje (G.R. No. 195163) clarifies two important areas of Philippine labor law: who may invoke a union security clause in a collective bargaining agreement (CBA), and what happens when workers stage a strike without complying with legal requirements. The ruling offers practical guidance for employers, union officers, and rank-and-file members navigating the delicate balance between union autonomy and the right to strike.

The Facts of the Case

The case involved union officers and members of the Ergonomic Systems Employees Union, a local union affiliated with a federation. The local union entered into a five-year CBA with the company. Before the CBA expired, the union officers secured independent registration of the local union, which prompted the federation to expel them for disloyalty and demand their dismissal from employment.

The company complied with the federation's demand and terminated the officers. In protest, union members staged a noise barrage, slow-down activities, and a picket line. Some refused to submit daily production reports, while others abandoned work. The company dismissed these members as well, leading to a complaint for illegal dismissal.

Issue: Who May Enforce a Union Security Clause?

The Court ruled that only the local union—not the federation—may invoke the union security clause in the CBA. Under the Labor Code, a chartered local union has its own legal personality. A local union does not owe its existence to the federation; it is a separate and distinct voluntary association. The federation acts merely as an agent of the local union, not as a principal.

Before an employer may terminate an employee under a union security clause, three requisites must be present: (1) the clause is applicable; (2) the union is requesting its enforcement; and (3) there is sufficient evidence to support the union's decision to expel the employee. In this case, the federation—not the local union—demanded dismissal, so the second requisite was lacking.

The Court also affirmed that a local union has the right to disaffiliate from its mother federation. The federation's remedy is limited to revoking the charter, not demanding the employee's dismissal.

Issue: When Is a Strike Illegal?

For a strike to be valid, the Labor Code requires: (a) a notice of strike filed with the National Conciliation and Mediation Board (NCMB); (b) a strike vote approved by majority of the union membership by secret ballot; and (c) a report of the voting results submitted to the NCMB at least seven days before the intended strike. These requirements are mandatory; failure to comply renders the strike illegal.

In this case, the union filed a notice of strike on 20 February 2002 and commenced the strike the next day. The strike vote was taken only on 2 April 2002, and the report was submitted on 4 April 2002—both after the strike had already begun. The strike was therefore illegal.

Liabilities of Union Officers vs. Members

The law distinguishes between union officers and ordinary members in illegal strikes. A union officer who knowingly participates in an illegal strike may be dismissed. An ordinary member, however, cannot be dismissed for mere participation; the employer must prove the member committed illegal acts during the strike.

Here, the union officers were validly dismissed because they conducted a strike despite knowing that no strike vote had been taken. The union members, however, could not be dismissed because the company failed to present evidence that they committed illegal acts such as obstruction or violence.

Back Wages and Separation Pay

The Court held that dismissed union members who participated in an illegal strike are not entitled to back wages, applying the principle of "a fair day's wage for a fair day's labor." Since they did not render work during the strike, they cannot claim wages for that period.

However, the Court awarded separation pay of one month's salary for every year of service in lieu of reinstatement. This was justified by the lapse of considerable time and the strained relations between the parties, which made reinstatement no longer feasible.

Practical Takeaways

  • Only the local union named in the CBA can enforce a union security clause. A federation cannot demand dismissal of employees, even if they disaffiliate from it.
  • A local union has the right to disaffiliate from its federation. The federation's remedy is to revoke the charter, not to cause the dismissal of employees.
  • Strike requirements are strictly mandatory. The strike vote and the seven-day report to the NCMB must be completed before the strike begins; doing them afterward makes the strike illegal.
  • Union officers face higher liability in illegal strikes. They may be dismissed for knowing participation, while ordinary members may be dismissed only if they commit illegal acts.
  • Employees who join illegal strikes generally cannot recover back wages, but may receive separation pay when reinstatement is no longer feasible.
