G.R. No. L-57473 August 15, 1988
SAN MIGUEL CORPORATION, petitioner, vs. NATIONAL LABOR RELATIONS COMMISSION and SAN MIGUEL BREWERY SALES FORCE UNION (PTGWO), respondents.

FACTS

Prior to the effectivity of the Labor Code on May 1, 1974, San Miguel Corporation (SMC) voluntarily granted its salesmen and helpers who suffered work-connected sickness or disability benefits exceeding those mandated by the old Workmen’s Compensation Act. These included basic salary, average commission, a sack of rice, free hospitalization, and cost of living allowance. Upon the Code’s effectivity, SMC registered with the Social Security System, began paying premiums to the State Insurance Fund, and discontinued its more generous private scheme, providing only the statutory benefits.
The San Miguel Brewery Sales Force Union (PTGWO) filed a complaint with the Bureau of Labor Relations in 1978, praying that SMC be compelled to pay the difference between its former, higher benefits and the lower amounts payable under the new State Insurance Fund. The Labor Arbiter and, on appeal, the National Labor Relations Commission (NLRC), ruled in favor of the Union. They held that SMC remained under a legal obligation to maintain its pre-Code practice, making it liable for the deficiency between the State Fund’s payments and its previous, more generous benefits.

ISSUE

Whether the NLRC committed grave abuse of discretion in ruling that SMC continues to be bound by its voluntarily assumed, pre-Labor Code obligation to pay higher work-connected disability benefits, despite the enactment of the new compulsory and exclusive state compensation program.

RULING

Yes. The Supreme Court granted the petition and nullified the NLRC decision. The legal logic is anchored on the exclusive and compulsory nature of the new Employees’ Compensation Program established under the Labor Code. The Court emphasized that the program is a social legislation designed to provide sure and prompt compensation through a state-administered insurance fund, funded by mandatory employer contributions. Critically, Article 173 of the Labor Code states that the State Insurance Fund’s liability is “exclusive and in place of all other liabilities” of the employer to the employee for work-connected disability or death.
By establishing this exclusive state scheme, the law effectively abolished all other forms of employer liability for work-connected incidents, whether based on contract, practice, or the old Workmen’s Compensation Act. SMC’s pre-Code practice was a voluntary, private arrangement. The advent of the compulsory public insurance system extinguished that separate, private obligation. To hold SMC liable for a “deficiency” would contravene the Code’s design by imposing a dual liability—one to the State Fund and another directly to the employee—which the law expressly sought to replace. Furthermore, the Court noted that jurisdiction over disputes regarding entitlement to benefits under the new program lies exclusively with the Social Security System and the Employees’ Compensation Commission, not the NLRC. Therefore, the NLRC’s assertion of jurisdiction and its substantive ruling imposing continued liability on SMC constituted grave abuse of discretion.
