G.R. No. 146206 ; August 1, 2011
SAN MIGUEL FOODS, INCORPORATED, Petitioner, vs. SAN MIGUEL CORPORATION SUPERVISORS and EXEMPT UNION, Respondent.

FACTS

Pursuant to the Supreme Court’s decision in G.R. No. 110399 , which held that supervisory employees 3 and 4 and exempt employees of San Miguel Foods, Inc. (SMFI) were not confidential employees and could form a bargaining unit, the DOLE-NCR conducted pre-election conferences for a certification election. A discrepancy arose in the list of eligible voters submitted by petitioner SMFI and respondent Union. On September 30, 1998, a certification election was conducted. On the same date, petitioner filed an Omnibus Objections and Challenge to Voters, arguing certain employees should not be allowed to vote as they were: (1) confidential employees; (2) assigned to live chicken operations not covered by the unit; (3) level 4 employees performing managerial work; (4) from the Barrio Ugong plant; (5) non-SMFI employees; and (6) members of other unions. After proceedings, including the opening of segregated ballots, the Med-Arbiter certified the Union as the exclusive bargaining agent. The DOLE Undersecretary affirmed but excluded four specific individuals from the bargaining unit. The Court of Appeals affirmed with modification, further excluding those holding the positions of Human Resource Assistant and Personnel Assistant. Petitioner filed this petition, arguing the CA expanded the bargaining unit’s scope beyond the Court’s definition in G.R. No. 110399 and erred in including the “Payroll Master” position.

ISSUE

1. Whether the Court of Appeals departed from jurisprudence by expanding the scope of the bargaining unit defined in G.R. No. 110399 .
2. Whether the Court of Appeals departed from jurisprudence on the definition of a “confidential employee” by ruling for the inclusion of the “Payroll Master” position in the bargaining unit.
3. Whether this petition is a rehash of issues raised in G.R. No. 110399 .

RULING

1. No, the CA did not depart from jurisprudence. The Supreme Court found no expansion of the bargaining unit. In G.R. No. 110399 , the Court held that employees of the San Miguel Corporation Magnolia Poultry Products Plants in Cabuyao, San Fernando, and Otis, having a “community or mutuality of interests,” constituted a single bargaining unit. This ruling was based on the nature of their work, wages, and common stake in concerted activities, not merely their physical plant locations. The Court clarified that the bargaining unit includes all supervisory levels 1 to 4 and exempt employees in the Poultry Division of SMFI, covering operations in Calamba, Laguna, Cavite, and Batangas, with home bases in Cabuyao or San Fernando. The inclusion of employees in “live” chicken operations (breeding and growing) is proper as they are part of the same integrated business operation (the Poultry Division) as the “dressed” chicken processing plants, sharing the same community of interests. The one-company, one-union policy was not violated.
2. No, the CA did not depart from the definition of a confidential employee. The Court affirmed the test from G.R. No. 110399 : confidential employees are those who (a) assist or act in a confidential capacity, and (b) to persons who formulate, determine, and effectuate management policies in the field of labor relations. The position of “Payroll Master,” while handling confidential data, primarily involves the mechanical and routine application of company policies and procedures related to payroll. The duties do not involve the formulation, determination, and effectuation of management policies concerning labor relations. Therefore, the Payroll Master is not a confidential employee disqualified from union membership.
3. The petition is not a mere rehash. While G.R. No. 110399 settled the general principles regarding the bargaining unit and confidential employees, the present case involved the specific application of those principles to resolve challenges to the eligibility of particular voters and the precise composition of the bargaining unit following the certification election. The Court’s ruling in this case applies and clarifies its prior decision in the context of implementing the certification election.
