Nippon Paint Philippines, Inc. vs. Nippon Paint Philippines Employees Association

A benefit voluntarily and consistently granted by an employer for at least two years ripens into a company practice that cannot be unilaterally withdrawn under Article 100 of the Labor Code, even where the employer claims the grant resulted from a payroll system error, absent substantial evidence to substantiate such claim and where the employer's yearly financial audits should have revealed the alleged error.

Nippon Paint Philippines, Inc. ("petitioner" or "Nippon") and the Nippon Paint Philippines Employees Association ("respondent" or "NIPPEA") were parties to a Collective Bargaining Agreement governing terms and conditions of employment, including holiday pay benefits exceeding statutory minimums. In 2009, Republic Act No. 9849 was enacted, declaring Eidul Adha as a regular holiday. Because the existing CBA enumerated specific regular holidays for which additional premium pay would be granted, the declaration of this new regular holiday raised the question of whether the CBA's additional holiday pay provisions would extend to Eidul Adha despite its absence from the negotiated list.

In 2007, Nippon Paint Philippines, Inc. and the Nippon Paint Philippines Employees Association entered into a Collective Bargaining Agreement effective January 1, 2007 until December 31, 2011. Section 1, Article 13 of the 2007 CBA provided that the company would pay all employees their daily rates on regular holidays even without work, and further granted union members premium pay equivalent to 200% of their regular daily rate on unworked regular holidays and 300% on worked regular holidays. The CBA enumerated the specific regular holidays covered, which did not include Eidul Adha. This premium holiday pay policy had been the company's practice for the past ten years.

In 2009, Republic Act No. 9849 was enacted, declaring Eidul Adha as a regular holiday. Despite the absence of Eidul Adha from the 2007 CBA's enumerated list of holidays, petitioner's employees received additional holiday pay corresponding to Eidul Adha in both 2010 and 2011. According to petitioner, these payments were the result of a glitch or error in its payroll system, which had automatically tagged Eidul Adha as a regular holiday and computed the corresponding premium pay. Petitioner maintained that the error was discovered only in 2012 and was promptly corrected.

On March 21, 2012, the parties executed a new CBA covering the period 2012 to 2016, renewing the 2007 CBA's holiday pay provisions but again excluding Eidul Adha from the enumerated list of regular holidays. Consistent with this exclusion, petitioner did not grant the additional holiday pay for Eidul Adha in 2012. Respondent objected, asserting that the grant of additional holiday pay for Eidul Adha in 2010 and 2011 had ripened into a company practice that could no longer be unilaterally withdrawn, as doing so would constitute an illegal diminution of benefits. Petitioner countered that the payments were erroneous and that the 2012 CBA's clear exclusion of Eidul Adha demonstrated the parties' intent not to extend the premium to that holiday.

The dispute was referred to a Voluntary Arbitrator, who ruled that the overpayment was a system error and not a voluntary employer practice, though no refund was required. The Court of Appeals reversed this ruling, holding that the grant had ripened into a company practice and remanding the case for computation of benefits. Petitioner elevated the matter to the Supreme Court via a Petition for Review on Certiorari under Rule 45.

• Payroll System Error: Petitioner maintained that the payment of additional holiday pay for Eidul Adha in 2010 and 2011 was an error due to the default program in its payroll system, which automatically tagged Eidul Adha as a regular holiday and computed the corresponding premium.
• CBA Exclusion as Evidence of Intent: Petitioner asserted that Eidul Adha was not included in the list of holidays in either the 2007 CBA or the 2012 CBA, and that the intention of the parties to exclude it from the other regular holidays was therefore clear and obvious.
• Insufficient Period for Company Practice: Petitioner argued that two years was too short a period for the grant of the benefit to be deemed a company practice.
• Entitlement to Refund: Petitioner contended that it was entitled to a refund of the payments made in 2010 and 2011 for the Eidul Adha holiday, as those payments were made solely due to a system error.

• Ripened Company Practice: Respondent argued that the CA correctly ruled that the grant of additional holiday pay for Eidul Adha had ripened into a company practice, and that petitioner could no longer recover the benefit as its withdrawal would be arbitrary, illegal, and tantamount to diminution of benefits.
• Incorporation by Law: Respondent asserted that despite the absence of a provision in the CBA, the law on regular holidays, which includes Eidul Adha, was deemed written into the contract.

• Company Practice: Whether the Court of Appeals erred in ruling that respondent and its members are entitled to an additional 100% pay in 2012 and 2013 for the Eidul Adha holiday.
• Refund: Whether the Court of Appeals erred in not ruling that petitioner is entitled to a refund for the payments made in 2010 and 2011 for the Eidul Adha holiday, which were allegedly only due to a system error.

• Company Practice: No. The grant of additional holiday pay for Eidul Adha for two years (2010 and 2011) ripened into a company practice that could no longer be unilaterally withdrawn under the principle of non-diminution of benefits embodied in Article 100 of the Labor Code.
• Refund: No. The petition was denied in its entirety, affirming the CA's ruling that the payments had ripened into a company practice; the claim of system error was unsubstantiated and could not justify either the discontinuance of the benefit or a refund.

• Company Practice: The principle of non-diminution of benefits under Article 100 of the Labor Code prohibits employers from reducing, diminishing, discontinuing, or eliminating supplements or benefits being enjoyed by employees. Diminution of benefits exists when four requisites are present: (1) the grant is founded on a policy or has ripened into a practice over a long period; (2) the practice is consistent and deliberate; (3) the practice is not due to error in the construction or application of a doubtful or difficult question of law; and (4) the diminution is done unilaterally by the employer. Jurisprudence has not laid down a hard-and-fast rule on the length of time required; the common denominator is the regularity and deliberateness of the grant over a significant period. The Court has found company practice where benefits were granted for six years, three years and nine months, three years and four months, and as short as two years. Here, petitioner granted additional holiday pay for Eidul Adha for two years (2010 and 2011), satisfying the requirement of a considerable period. The claim that the payments resulted from a payroll system error was rejected. Applying the reasoning in Sevilla Trading Co. vs. Semana, the Court found it implausible that a company conducting meticulous yearly financial audits would fail to discover the alleged error for two years. Petitioner failed to adduce substantial evidence to support its claim of mistake. The exclusion of Eidul Adha from the 2012 CBA was immaterial because the source of the employees' entitlement was company practice, not the CBA. All four requisites of diminution of benefits were satisfied, and petitioner's unilateral discontinuance violated Article 100 of the Labor Code.

• Refund: The denial of the petition necessarily rejected petitioner's claim for refund. Having established that the payments ripened into a company practice, the Court implicitly affirmed that the employees had a vested right over the benefit. The unsubstantiated nature of the system error claim precluded any basis for recovering payments that had become part of the employees' vested benefits.

• Non-Diminution of Benefits (Article 100, Labor Code) — Employees have a vested right over existing benefits voluntarily granted by the employer; such benefits cannot be reduced, diminished, discontinued, or eliminated. The doctrine is anchored on the constitutional mandate to protect workers' rights and afford full protection to labor. Applied in this case to prohibit petitioner from unilaterally withdrawing the additional holiday pay for Eidul Adha after it had ripened into a company practice.

• Company Practice — Requisites — There is diminution of benefits when: (1) the grant or benefit is founded on a policy or has ripened into a practice over a long period of time; (2) the practice is consistent and deliberate; (3) the practice is not due to error in the construction or application of a doubtful or difficult question of law; and (4) the diminution or discontinuance is done unilaterally by the employer. To establish company practice, the employee must prove by substantial evidence that the giving of the benefit was done over a long period of time, consistently and deliberately, with an indubitable showing that the employer agreed to continue giving the benefit knowing fully well that the employees are not covered by any provision of law or agreement requiring payment thereof.

• Length of Time for Company Practice — No hard-and-fast rule prescribes the length of time required for a benefit to ripen into company practice. The decisive factor is the regularity, deliberateness, and voluntariness of the grant over a significant period. Jurisprudence has recognized periods of six years, three years and nine months, three years and four months, and as short as two years as sufficient to constitute company practice.

• Payroll System Error as Defense — A bare claim of payroll system error is insufficient to defeat a finding of company practice, particularly where the employer conducts yearly financial audits that should reveal the alleged error. The employer must adduce substantial evidence to prove the mistake; failure to do so renders the defense unmeritorious.

• "Here, the Court finds that petitioner's grant of additional holiday pay for Eidul Adha to its employees for a period of two years ripened into a company practice. Thus, petitioner can no longer withdraw the grant of such additional holiday pay without violating the principle of non-diminution of benefits." — This passage states the ratio decidendi, applying the company practice doctrine to a two-year period of voluntary grant.

• "To be considered as a regular company practice the employee must prove by substantial evidence that the giving of the benefit is done over a long period of time, and that it has been made consistently and deliberately." — This is the canonical formulation of the company practice test as articulated in Vergara, Jr. vs. Coca-Cola Bottlers Philippines, Inc., frequently cited in subsequent labor jurisprudence.

• "The Court finds as immaterial to the case the fact that Eidul Adha was not included in the 2012 CBA's list of regular holidays for which petitioner's employees would receive additional holiday pay. The source of the entitlement of petitioner's employees to the subject additional benefit is not the CBA but company practice." — This passage resolves the interplay between CBA provisions and company practice, establishing that vested rights from company practice are independent of subsequent CBA exclusions.

• Sevilla Trading Co. vs. Semana, 472 Phil. 220 (2004) — Controlling analogy. The Court found that an employer's inclusion of non-basic benefits in 13th month pay computation for two to three years constituted company practice, rejecting the defense of payroll error. The Court applied the same reasoning to reject petitioner's system error claim, noting that yearly financial audits should have revealed the alleged error.

• Vergara, Jr. vs. Coca-Cola Bottlers Philippines, Inc., 707 Phil. 255 (2013) — Followed for the formulation of the company practice test, requiring substantial evidence of consistent and deliberate grant over a long period with the employer's knowledge that payment was not required by law or agreement.

• University of the East vs. University of the East Employees' Association, 673 Phil. 273 (2011) — Cited for the principle that employees have a vested right over existing benefits voluntarily granted, which cannot be reduced, diminished, discontinued, or eliminated.

• Davao Fruits Corp. vs. Associated Labor Unions, 296-A Phil. 587 (1993) — Cited as illustrative of company practice found where benefits were granted for six years.

• Tiangco vs. Leogardo, Jr., 207 Phil. 235 (1983) — Cited as illustrative of company practice found where a fixed monthly emergency allowance was granted for three years and three months.

• Article 94, Labor Code of the Philippines — Mandates that every worker shall be paid his or her regular daily wage during regular holidays. Employees required to work on a regular holiday shall be paid at least 200% of their regular daily wage. Applied as the statutory baseline against which petitioner's additional premium pay (200% for unworked holidays, 300% for worked holidays) exceeded the legal minimum.

• Article 100, Labor Code of the Philippines — Prohibits the elimination or diminution of supplements or other employee benefits being enjoyed at the time of promulgation of the Code. Applied as the statutory basis for ruling that petitioner could not unilaterally withdraw the additional holiday pay for Eidul Adha after it had ripened into a company practice.

• Article 4, Labor Code of the Philippines — Provides that all doubts in the implementation and interpretation of the Labor Code shall be rendered in favor of labor. Cited as supporting the constitutional policy underlying the non-diminution principle.

• Republic Act No. 9849 — Declared Eidul Adha as a regular holiday, approved on December 11, 2009. The enactment of this law occasioned the dispute, as petitioner's payroll system automatically treated Eidul Adha as a regular holiday, triggering the additional premium pay under the CBA's holiday pay provisions.

Hernando, Rosario, and J. Lopez, JJ., concurred. Leonen (Chairperson), J., filed a concurring opinion.

Justice Leonen's concurring opinion elaborated on the constitutional and labor law foundations of the non-diminution principle, emphasizing that the 1987 Constitution mandates the protection of workers' rights and the promotion of their welfare. He underscored that the holiday premium was founded on the CBA, which had been company policy for ten years, providing additional reason to believe the grant for Eidul Adha was consistent, deliberate, and customary. He rejected petitioner's reliance on the 2012 CBA's exclusion of Eidul Adha, reiterating that the employees' vested right was anchored on company practice, not the agreement. He agreed that two years sufficed for a grant of benefits to be deemed company practice.
