Arco Metal Products Co., Inc. vs. SAMARM-NAFLU

An employer's repeated and consistent grant of benefits beyond what the CBA or law requires, even if claimed to have been made in error, ripens into voluntary company practice that cannot be reduced, diminished, discontinued, or eliminated, provided the employer fails to substantiate its claim of mistake with corroborating evidence. Jurisprudence has not laid down any rule specifying a minimum number of years within which a company practice must be exercised to constitute voluntary company practice.

Arco Metal Products Co., Inc. is a company engaged in the manufacture of metal products, and respondent SAMARM-NAFLU is the labor union representing its rank-and-file employees. The parties are bound by a Collective Bargaining Agreement (CBA) whose relevant provisions on vacation leave, sick leave, emergency leave, and 13th month pay and bonus have been carried over from four previous CBAs covering the period from 28 August 1990 to 31 July 2002. The CBA provisions on vacation and sick leave require employees to have rendered at least one year of service to be entitled to the full sixteen days of leave with pay, while the 13th month pay and bonus provisions contain no explicit one-year service requirement. The dispute centers on whether the employer's past practice of paying these benefits in full to employees who served less than twelve months constitutes a voluntary company practice protected by the principle of non-diminution of benefits under Article 100 of the Labor Code.

Arco Metal Products Co., Inc. is a manufacturer of metal products, and respondent Samahan ng mga Manggagawa sa Arco Metal-NAFLU (SAMARM-NAFLU) is the certified labor union representing the company's rank-and-file employees. The parties are governed by a Collective Bargaining Agreement whose provisions on vacation leave, sick leave, emergency leave, and 13th month pay and bonus have been carried over substantially unchanged from four previous CBAs spanning from 28 August 1990 to 31 July 2002.

Sometime in December 2003, petitioner paid the 13th month pay, bonus, and leave encashment of three union members in amounts proportional to the service they actually rendered during the year, rather than in full. The three employees were Rante Lamadrid, who was sick from 27 August 2003 to 27 February 2004; Alberto Gamban, who was under suspension from 10 June 2003 to 1 July 2003; and Rodelio Collantes, who was sick from August 2003 to February 2004. None of the three had rendered a full twelve months of service within the year.

Respondent protested the prorated scheme, asserting that on several prior occasions petitioner had paid the same benefits in full to employees who likewise had not served a full twelve months. These instances involved seven employees across the years 1992, 1993, 1994, 1996, 1999, 2002, and 2003: Percival Bernas (sickness, July to November 1992), Cezar Montero (sickness, December 1992 to February 1993), Wilson Sayod (sickness, May to July 1994), Nomer Becina (suspension, September to October 1996), Ronnie Licuan (sickness, November to December 1999), Guilbert Villaruel (sickness, August 2002 to February 2003), and Melandro Moque (sickness, August to September 2003). Respondent contended that the prorated payment violated the rule against diminution of benefits under Article 100 of the Labor Code and filed a complaint before the National Conciliation and Mediation Board, after which the parties submitted the case for voluntary arbitration.

Petitioner, for its part, maintained that the full payments to the seven employees were erroneous. It relied on the affidavit of Joselito Baingan, its manufacturing group head, who stated that it was never the intention or policy of management to grant the benefits in full regardless of length of service. Petitioner explained that the error went unnoticed because each case involved only one employee per year vis-à-vis the company's 170 employees, and that the accounting department discovered the error only in 2003 when three employees had prolonged absences. The voluntary arbitrator credited this explanation and ruled in favor of petitioner, finding no established company practice. The Court of Appeals reversed, finding that petitioner had failed to present evidence corroborating its claim of error and questioning why it took eleven years to discover the alleged mistake. The appellate court concluded that a voluntary practice of full payment existed and ordered that the benefits be paid in full irrespective of actual service rendered.

• CBA Interpretation: Petitioner argued that the CBA provisions contain a one-year cutoff for entitlement to full benefits, as evidenced by the phrase "who have rendered at least one (1) year of service" in the vacation and sick leave provisions, and that the 13th month pay and bonus should be computed in proportion to actual service rendered pursuant to law and the CBA.
• No Voluntary Practice: Petitioner maintained that the full payment of benefits to seven employees who had not served a full year was erroneous, occurring in isolated cases across several years, and did not constitute voluntary employer practice. It characterized the situation as a "clear oversight" that should not be taken against it.
• Requisites of Company Practice Not Met: Petitioner argued that for a benefit grant to be considered company practice, it must have been practiced over a long period of time and must be shown to be consistent, deliberate, and intentional—elements absent here. It pointed out that the CBA had never been modified to incorporate the giving of full benefits regardless of length of service, proving the grant had not ripened into company practice.

• Non-Diminution of Benefits: Respondent protested the prorated payment scheme, claiming that petitioner had on several occasions paid the same benefits in full to employees who had not served a full twelve months, and that the prorated payment violated the rule against diminution of benefits under Article 100 of the Labor Code.

• CBA Interpretation: Whether the CBA provisions require an employee to render at least one year of service to be entitled to the full monetization of vacation and sick leave benefits, and whether the 13th month pay and bonus should be computed proportionately to actual service rendered.
• Voluntary Company Practice: Whether petitioner's repeated full payment of 13th month pay, bonus, and leave encashment to employees who had not served a full year constitutes voluntary employer practice that can no longer be reduced, diminished, discontinued, or eliminated under the principle of non-diminution of benefits.

• CBA Interpretation: Yes. The CBA clearly requires at least one year of service for entitlement to the full sixteen days of vacation and sick leave monetization, and the 13th month pay and bonus should be computed at 1/12 of total compensation or in proportion to actual service rendered, as the CBA gave no meaning different from that provided by law.
• Voluntary Company Practice: Yes. Petitioner's repeated, voluntary, and consistent grant of full benefits to employees regardless of length of service across the years 1992 to 2003 ripened into an established company practice that cannot be unilaterally withdrawn, the employer having failed to substantiate its claim of error with corroborating evidence.

• CBA Interpretation: The applicable CBA provisions on vacation leave (Article XIV, Section 1) and sick leave (Article XV, Section 1) explicitly state that employees "who have rendered at least one (1) year of service" shall be entitled to sixteen days of leave with pay. The clear wording does not allow any other interpretation. Anent the 13th month pay (Article XVIII, Section 1) and bonus (Article XVIII, Section 2), the CBA did not give any meaning different from that provided by law; thus, the 13th month pay should be computed at 1/12 of the total compensation received for the whole calendar year, and the bonus is equivalent to the 13th month pay or in proportion to actual service rendered. The Court agreed with the voluntary arbitrator's findings on this point.

• Voluntary Company Practice: Although the Court is not a trier of facts in Rule 45 petitions and the findings of the Court of Appeals are generally conclusive and binding, an exception applies when the appellate court's factual findings are contrary to those of the lower tribunals—such as occurred here, where the Court of Appeals' conclusions differed from the voluntary arbitrator's. Petitioner had granted full benefits to seven employees who had not served a full year across the years 1992, 1993, 1994, 1999, 2002, and 2003. While only seven employees benefited, this was an established practice nonetheless. Jurisprudence has not laid down any rule specifying a minimum number of years within which a company practice must be exercised to constitute voluntary company practice; it can be six years, three years, or even as short as two years. Petitioner's claim of error, supported only by an affidavit of its manufacturing group head, was insufficient. In cases involving money claims of employees, the employer bears the burden of proving that employees received wages and benefits in accordance with law. Petitioner could have presented evidence of other employees who received prorated benefits to bolster its theory of mistake, but no such evidence was presented. The principle of non-diminution of benefits, founded on the constitutional mandate to protect workers' rights and promote their welfare, prohibits the reduction, diminution, discontinuance, or elimination of any benefit being enjoyed by employees.

• Non-Diminution of Benefits — Any benefit and supplement being enjoyed by employees cannot be reduced, diminished, discontinued, or eliminated by the employer. The principle is founded on the constitutional mandate to "protect the rights of workers and promote their welfare" (Article II, Section 18) and "to afford labor full protection" (Article XIII, Section 3), which in turn is the basis of Article 4 of the Labor Code requiring that all doubts in the implementation and interpretation of the Labor Code be rendered in favor of labor. Applied here, the employer's repeated full payment of benefits to employees who had not served a full year could not be unilaterally discontinued through prorated payment.

• Voluntary Company Practice — A benefit voluntarily and consistently extended by the employer to its employees, even if not required by law or the CBA, ripens into company practice and can no longer be peremptorily withdrawn. Jurisprudence has not laid down any rule specifying a minimum number of years within which a company practice must be exercised to constitute voluntary company practice; it can be six years, three years, or even as short as two years. A claim of error or mistake, supported only by a self-serving affidavit and uncorroborated by other evidence, is insufficient to negate the existence of voluntary practice. In cases involving money claims of employees, the employer bears the burden of proving that employees received wages and benefits in accordance with law.

• "Jurisprudence has not laid down any rule specifying a minimum number of years within which a company practice must be exercised in order to constitute voluntary company practice." — This passage articulates the flexible temporal standard for company practice, a point frequently cited in subsequent labor cases on non-diminution of benefits.

• "Petitioner cannot shirk away from its responsibility by merely claiming that it was a mistake or an error, supported only by an affidavit of its manufacturing group head." — This establishes that an employer's unilateral claim of error, without corroborating evidence, cannot defeat a finding of voluntary company practice.

• "Any benefit and supplement being enjoyed by employees cannot be reduced, diminished, discontinued or eliminated by the employer." — This is the canonical formulation of the non-diminution principle as applied in this case, rooted in the constitutional mandate to protect labor.

• Davao Fruits Corporation vs. Associated Labor Unions, G.R. No. 85073, 24 August 1993, 225 SCRA 562 — Followed. The employer had freely and continuously included in the computation of the 13th month pay items expressly excluded by law; the act, though not conforming to law, had ripened into a practice and could not be withdrawn, reduced, diminished, discontinued, or eliminated. Cited to support the proposition that voluntary employer practice, even if erroneous, becomes entrenched.

• Sevilla Trading Company vs. Semana, G.R. No. 152456, 28 April 2004, 428 SCRA 239 — Followed. The employer's act of including non-basic benefits in the computation of the 13th month pay was a voluntary act that had ripened into company practice which cannot be peremptorily withdrawn. Also cited for the proposition that no minimum number of years is required for company practice to ripen.

• Davao Integrated Port Stevedoring Services vs. Abarquez, G.R. No. 102132, 19 March 1993, 220 SCRA 197 — Followed. The Court ordered payment of the cash equivalent of unenjoyed sick leave benefits to intermittent workers after finding that the employer had granted these benefits for almost four years until the grant was stopped due to a different CBA interpretation. The employer cannot unilaterally withdraw an existing privilege.

• Tiangco vs. Leogardo, Jr., 207 Phil. 2235 (1983) — Cited for the general principle that any benefit and supplement being enjoyed by employees cannot be reduced, diminished, discontinued, or eliminated by the employer.

• Mark Roche International vs. NLRC, 372 Phil. 238 (1999) — Cited for the rule that in cases involving money claims of employees, the employer has the burden of proving that employees received wages and benefits in accordance with law.

• Article 100, Labor Code — Prohibits the diminution of benefits enjoyed by employees at the time of the promulgation of the Labor Code. Respondent invoked this provision to challenge the prorated payment scheme. The majority applied the principle of non-diminution of benefits through this provision and related jurisprudence, though Justice Brion's separate concurring opinion clarified that Article 100 refers solely to non-diminution of benefits enjoyed at the time of the Labor Code's promulgation, and that the true basis for prohibiting withdrawal of established benefits is the mutuality of contracts under Article 1308 of the Civil Code.

• Article 4, Labor Code — Provides that all doubts in the implementation and interpretation of the Labor Code, including its implementing rules and regulations, shall be rendered in favor of labor. Applied to resolve any doubt about the character of the employer's enhanced computations in favor of the employees.

• Article II, Section 18, Constitution — Mandates the State to "protect the rights of workers and promote their welfare." Cited as the constitutional foundation of the non-diminution principle.

• Article XIII, Section 3, Constitution — Mandates the State to "afford labor full protection." Cited alongside Article II, Section 18 as the constitutional basis for non-diminution of benefits.

• Article 1308, Civil Code — Embodies the principle of mutuality of contracts, providing that the terms of a contract—both express and implied—cannot be withdrawn except by mutual consent or agreement of the contracting parties. Discussed in Justice Brion's separate concurring opinion as the true legal basis for prohibiting unilateral withdrawal of established benefits.

• CBA Articles XIV, XV, XVI, and XVIII — The collective bargaining agreement provisions on vacation leave, sick leave, emergency leave, and 13th month pay and bonus. The Court found that Articles XIV and XV clearly require at least one year of service for full leave entitlement, while Article XVIII did not provide any meaning different from the statutory computation of 13th month pay and bonus.

Quisumbing (Chairperson), Carpio Morales, and Velasco, Jr., JJ., concurred.

Brion, J., filed a separate concurring opinion clarifying that the true legal basis for the prohibition against diminution of established benefits is not Article 100 of the Labor Code—which refers solely to non-diminution of benefits enjoyed at the time of the Labor Code's promulgation—but rather the principle of mutuality of contracts embodied in Article 1308 of the Civil Code. He explained that the employer-employee relationship is contractual, based on both express and implied terms of the employment contract, and that benefits the employer has freely, voluntarily, and consistently extended become implied terms that cannot be withdrawn except by mutual consent. The lack of such consent or agreement was precisely the basis for the employees' complaint.
