Case Summary (G.R. No. 102132)
Petitioner
Davao Integrated Port Stevedoring Services Corporation challenged an arbitration award directing it to grant and continue commutation of the unenjoyed portion of sick leave with pay to intermittent field workers who are members of the regular labor pool and the present regular extra labor pool, arguing the CBA’s language limited commutation to regular non‑intermittent workers.
Respondent
ATU‑TUCP sought enforcement of the CBA provision as applied by the company in practice, arguing discontinuance of commutation was a deviation from the parties’ intent, violated labor law principles protecting existing benefits, and resulted in discriminatory treatment between intermittent and non‑intermittent workers.
Key Dates
CBA originally executed: October 16, 1985.
CBA renewed: April 15, 1989 (expanded coverage to include present Regular Extra Labor Pool).
Arbitral Award: September 10, 1991.
Supreme Court decision (appeal): March 19, 1993.
(Decision falls after 1990; the 1987 Constitution is the constitutional framework applicable to the decision.)
Applicable Law and Legal Framework
Primary legal framework applied: the 1987 Constitution as the basis for public policy and labor protection (decision date after 1990), the Labor Code provisions governing CBAs and voluntary arbitration (notably Articles 252 and 261 as discussed in the case), and principles established by prior labor jurisprudence cited in the record concerning the nature, interpretation, and enforceability of collective bargaining agreements and existing benefits (including that CBA terms are law between parties, CBAs are contracts impressed with public interest, and established benefits cannot be unilaterally withdrawn under Article 100 of the Labor Code).
Collective Bargaining Agreement: Relevant Provisions
Article VIII, Section 1 (1985 and 1989 CBA) provided a 15‑day sick leave with pay each year for regular non‑intermittent workers who rendered at least one year’s service, with a provision that any unenjoyed portion within that year shall be converted to cash at the end of the year. A proviso appeared stating only regular workers whose work are not intermittent are entitled to "the herein sick leave privilege." Article VIII, Section 3 (1985; carried into 1989 and expanded to include present Regular Extra Labor Pool) provided a graduated schedule of vacation and sick leave days for intermittent field workers based on hours worked per calendar year, subject to conditions of Section 1 (one year service and company‑designated physician certification).
Factual Background and Company Practice
Under the 1985 CBA and during its effective period through three months after the April 15, 1989 renewal, the company regularly paid intermittent field workers (members of the regular labor pool and present regular extra labor pool) the cash equivalent of any unenjoyed sick leave pursuant to the CBA provisions and practice. After managerial change in June 1989, the company stopped such payments, asserting the 1989 CBA language (particularly the proviso in Section 1) limited commutation to non‑intermittent regular workers and thus intermittent workers were not entitled to cash conversion.
Dispute, Procedural History, and Arbitration
The Union protested the discontinuance and, after failed settlement efforts, filed for voluntary arbitration before the NCMB Regional Arbitration Branch XI. Both parties mutually designated Abarquez as voluntary arbitrator. After position papers were submitted, the arbitrator issued an award (September 10, 1991) directing the company to grant and extend commutation of the unenjoyed portion of sick leave to the intermittent workers from the time of discontinuance and henceforth. The company filed a petition for certiorari seeking annulment of the award.
Issue Presented
Whether the company lawfully discontinued commutation of the unenjoyed portion of sick leave for intermittent workers by relying on the proviso in Section 1 of Article VIII of the 1989 CBA, or whether the arbitrator correctly interpreted the CBA and enforced commutation as an existing benefit that could not be unilaterally withdrawn.
Court’s Legal Analysis — Interpretation of the CBA
The Court emphasized that a CBA is not an ordinary contract: it is a labor contract infused with public interest and must be construed liberally and realistically to effectuate its protective purpose. The Court rejected the company’s isolated reading of the proviso in Section 1, holding that Section 1 must be read in relation to Section 3. Section 1’s proviso limiting a fixed 15‑day sick leave to non‑intermittent workers refers to the fixed nature of the 15‑day entitlement, not to commutation generally. Intermittent workers under Section 3 receive a variable number of sick leave days (up to 15) based on hours worked; they are subject to the same qualifying conditions (at least one year’s service and physician’s certification). Thus, commutation of any unenjoyed portion, by parity and by the express structure of the CBA, applies to intermittent workers who qualify.
Court’s Findings on Practice, Estoppel, and Labor Policy
The Court found that the company’s prior practice of paying the cash equivalent to intermittent workers during the life of the 1

- Article VIII, Section 1 (quoted in petition):
- Grants 15 days sick leave with pay each year to every regular non-intermittent worker who has rendered at least one year of service.

- If not enjoyed within one year period of the current year, any unenjoyed portion shall be converted to cash and paid at the end of the said one-year period.
- Proviso: “And provided however, that only those regular workers of the company whose work are not intermittent, are entitled to the herein sick leave privilege.”
- Article VIII, Section 3 (1985 CBA, quoted):

- The same hours-based schedule and conditions for availment, referencing Sections 1 and 2, are reproduced.
Factual Background
- During the effectivity of the 1985 CBA until three months after its renewal on April 15, 1989 (until July 1989), a period totaling three years and nine months, intermittent field workers who were members of the regular labor pool and present regular extra labor pool rendering between 750 and 1,500 hours were extended sick leave with pay benefits.
- During that period the unenjoyed portion of sick leave at the end of the calendar year was converted to cash and paid pursuant to Sections 1 and 3 of the CBA; the number of days of sick leave depended on hours rendered as per Section 3 schedule.
- A management change occurred: Mr. Benjamin Marzo replaced Mr. Cecilio Beltran, Jr. (resigned June 1989). Under the new assistant manager, petitioner-company discontinued payment (commutation) of the cash equivalent of unenjoyed sick leave for intermittent workers, on the ground such workers are not entitled under Sections 1 and 3 of the 1989 CBA.
- The Union (ATU-TUCP), as exclusive bargaining agent, objected to discontinuance and sought voluntary arbitration after failure to amicably settle the interpretation dispute.
Claim, Arbitration and Award
- Union filed a complaint for enforcement of the CBA, invoking voluntary arbitration before the National Conciliation and Mediation Board, Regional Arbitration Branch XI, Davao City.
- Parties mutually designated Ruben Abarquez, Jr. as voluntary arbitrator.
- After position papers were filed, the Voluntary Arbitrator issued an Award on September 10, 1991 directing management to grant and extend the sick leave privilege of commutation of the unenjoyed portion of sick leave to all intermittent field workers who are members of the regular labor pool and the present extra pool, in accordance with the CBA, from the time it was discontinued and henceforth. (Dispositive wording quoted in the decision: “WHEREFORE … the management … is hereby directed to grant and extend the sick leave privilege of the commutation of the unenjoyed portion of the sick leave of all the intermittent field workers who are members of the regular labor pool and the present extra pool in accordance with the CBA from the time it was discontinued and henceforth. SO ORDERED.”)
Petitioner’s Contentions (Grounds for the Instant Petition)
- Petitioner argued that the last sentence (proviso) of Section 1, Article VIII of the 1989 CBA clearly limits the conversion-to-cash privilege to regular workers “whose work are not intermittent,” thereby excluding intermittent workers.
- Petitioner maintained that prior payments of cash equivalents to intermittent workers under the former management (Mr. Beltran) resulted from a misinterpretation of Sections 1 and 3 of the 1985 CBA, and that the company properly rectified such error upon managerial change.
- Petitioner contended that an “error in payment” cannot ripen into a binding company practice and therefore the company was entitled to stop payments.
- Petitioner objected to the authority of the Voluntary Arbitrator to direct commutation, implying the arbitrator exceeded authority.
Union’s Contentions and Relief Sought
- The Union contended discontinuance of commutation was a deviation from the true intent of the parties in negotiating the CBA.
- The Union argued discontinuance violated the labor law pr
