G.R. No. 245918 . November 29, 2022
Mindanao International Container Terminal Services, Inc., Petitioner, vs. Mindanao International Container Terminal Services, Inc. Labor-Union-Federation of Democratic Labor Organization (MICTSILU-FDLO), et al., Respondents.

FACTS

Petitioner MICTSI and respondent union MICTSILU-FDLO entered into a Collective Bargaining Agreement (CBA) effective from March 20, 2015, to March 20, 2020. The CBA contained provisions on promotion and the principle of equal pay for equal work. Specifically, Article 6, Section 3 stated that a promoted employee “shall receive the pay of the job to which he has been promoted,” while Article 7, Section 1 affirmed the company’s agreement with “the principle of equal pay for equal work.”
A dispute arose when several union members, the individual respondents, were promoted to higher plantilla positions but received starting salaries lower than those of incumbent employees in the same positions. For instance, Lyle Cajoles, promoted to QGC Operator, received a basic salary of ₱16,864.00, while Michael Maneja, already in that position, received ₱20,095.67. The union contended before the Accredited Voluntary Arbitrator (AVA) that this practice violated the CBA’s equal pay principle, arguing that promoted employees should receive the highest rate for the position.

ISSUE

Whether the practice of paying newly promoted employees a starting salary lower than that of longer-tenured employees in the same position violates the “equal pay for equal work” principle under the parties’ CBA.

RULING

No, the practice does not violate the CBA. The Supreme Court reversed the Court of Appeals and reinstated the AVA’s decision dismissing the complaint. The Court held that the principle of “equal pay for equal work” under Article 7, Section 1 of the CBA does not mandate absolute uniformity in wages for employees holding the same position. The legal logic is grounded in the permissible and reasonable classification of employees based on valid factors such as length of service, merit, and performance.
The Court explained that the constitutional guarantee of equal protection allows for substantive classification. A distinction in pay based on seniority or merit constitutes a substantial and reasonable differentiation germane to legitimate employment objectives like rewarding loyalty and incentivizing performance. This does not constitute unlawful wage discrimination. The CBA provision in Article 6, Section 3, stating a promoted employee “shall receive the pay of the job,” was correctly interpreted by the AVA to mean the entry rate for that job classification, not the highest rate paid to any incumbent. To rule otherwise would negate legitimate salary progression mechanisms and discourage the grant of merit increases. The respondents failed to prove that the salary differences were based on arbitrary or discriminatory grounds unrelated to valid job-related qualifications. Therefore, the employer’s practice was upheld as a valid exercise of management prerogative, consistent with the CBA and existing labor jurisprudence.
