G.R. No. 74425 , October 7, 1986
Bulletin Publishing Corporation vs. Hon. Augusto S. Sanchez, et al.

FACTS

Petitioner Bulletin Publishing Corporation sought to prevent its supervisory employees, members of the newly formed Bulletin Publishing Corporation Supervisors Union (BSU), from staging a strike. The company also prayed for the nullification of BSU’s registration certificate. The core dispute was whether supervisors could form a separate union for collective bargaining, distinct from the existing rank-and-file union, the Bulletin Employees Union (BEU). The BEU had a collective bargaining agreement effective from 1984 to 1987, and supervisory employees had never sought inclusion in it.
On March 12, 1986, 25 out of 48 supervisors formed the BSU and obtained a registration certificate from the Ministry of Labor on March 26, 1986. The BSU then demanded recognition as the sole bargaining agent for supervisors and filed a notice of strike on April 12, 1986, alleging unfair labor practices. The company refused recognition, filing a petition for cancellation of BSU’s registration on April 25, 1986, arguing that supervisors were prohibited from forming unions under the Labor Code. Faced with an impending strike and the Labor Minister’s inaction on its petition for assumption of jurisdiction, the company invoked the Supreme Court’s equity jurisdiction to avert irreparable harm to its daily publishing operations.

ISSUE

Whether supervisory employees may lawfully form a separate labor union for collective bargaining purposes under the Labor Code.

RULING

The Supreme Court ruled that supervisory employees may not form a separate union. The legal logic is anchored on Article 246 of the Labor Code, which explicitly excludes managerial employees from the right to self-organization. The Court found that most of the private respondents were managerial employees. Furthermore, Section 11, Rule II, Book V of the Implementing Rules clearly stated that supervisory unions were no longer recognized or allowed to exist. Allowing such a union would create a conflict of interest, as supervisors are part of management’s rank and owe loyalty to the employer while simultaneously owing solidarity to the union members they supervise. This dual allegiance could undermine management prerogatives and disrupt industrial peace.
The Court emphasized that the promotions of employees to supervisory positions were a legitimate management prerogative and not a scheme to undermine union membership. Since the concerted activities (the threatened strike) aimed to compel the employer to violate the clear mandate of the Labor Code, judicial intervention via equity jurisdiction was warranted to prevent irreparable injury to the business. Consequently, the temporary restraining order against the strike was made permanent, and the public respondents were directed to resolve the petition for cancellation of BSU’s registration certificate in light of this ruling.
