Case Summary (G.R. No. 261807)

Applicable Law

The governing law in this case is the 1987 Philippine Constitution and the Labor Code of the Philippines, particularly provisions regarding wage differentials and unfair labor practices.

Background of the Case

The conflict arose following a Collective Bargaining Agreement (CBA) signed on July 2, 1997, effective from August 1, 1996, to July 31, 2001, between the respondent union and the petitioner company. The issue centered on the disparities in wages and benefits between supervisors who were former employees of Philex Mining Corporation, referred to as "ex-Padcal" supervisors, and locally hired supervisors. The latter were allegedly receiving lower salaries and fewer benefits despite performing similar duties.

Initial Arbitrator's Decision

After filing a complaint with the National Conciliation and Mediation Board (NCMB), the Voluntary Arbitrator ruled on January 14, 2000, in favor of the union, stating that the pay structure was discriminatory and violated Article 248(e) of the Labor Code, which prohibits unfair labor practices. The decision ordered the petitioner to adjust the wages of local supervisors to be equal to their ex-Padcal counterparts and to pay wage differentials backdated to November 1, 1998.

###Modification of Decision by Arbitrator
On February 29, 2000, in response to motions for reconsideration from both parties, the Voluntary Arbitrator modified his initial decision, concluding that while disparities existed, they were not discriminatory. He ordered only a uniform wage increase of P800 per month for supervisors and computed wage differentials from October 1, 1999, instead.

Appellate Court Proceedings

The respondent union raised concerns regarding the Voluntary Arbitrator's decision through a petition for review to the Court of Appeals, which ultimately ruled that the petitioner failed to convincingly demonstrate that there was no wage discrimination against locally hired supervisors. The appellate court found the petitioner’s explanations for wage disparities insufficient and reinstated the earlier decision of January 14, 2000, with the wage adjustments made effective as of August 1, 1997.

Issues on Appeal

The petitioners took issue with the appellate court's ruling, particularly regarding the timeliness of their motions for reconsideration, asserting improper notice was given since it was sent to their liaison office rather than their legal counsel. They further contested their solidary liability as corporate officers for the obligations of Philex Gold and argued that the "equal pay for equal work" doctrine should not eliminate management's ability to adjust pay based on valid considerations such as seniority and experience.

Court's Findings on Notice and Timing

The Supreme Court agreed that notice to the liaison office was insufficient as service should have been directed to the petitioners' counsel as per the NCMB Procedural Guidelines, allowing their motion for reconsideration to be considered timely filed.

Corporate Officers' Liability

On the issue of whether the corporate officers should be held solidarily liable, the Court reaffirmed that corporate officers are typically no
