G.R. No. L-16994; June 30, 1961
MANILA PORT SERVICE and MANILA RAILROAD COMPANY, petitioners, vs. COURT OF INDUSTRIAL RELATIONS AND ASSOCIATED WATERFRONT SUPERVISORS UNION (PIWO), respondents.

FACTS

The Associated Waterfront Supervisors Union (PIWO) filed a petition with the Court of Industrial Relations (CIR) against Manila Port Service and Manila Railroad Company. The union sought recovery of overtime compensation for work its members performed on Saturdays from June 22 to September 30, 1957, invoking Republic Act No. 1880 and Commonwealth Act No. 444. The petition alleged that the employers’ refusal to pay had created a labor dispute likely to cause a strike. The petitioners denied the claim, asserting the CIR lacked jurisdiction and that no overtime was due.
The CIR issued an order directing the petitioners to pay the claimed overtime compensation. The petitioners’ motion for reconsideration was denied by the court en banc, prompting this petition for certiorari. The petitioners reiterated their jurisdictional challenge and argued on the merits that the collective bargaining contract, which set working hours from 8:00 a.m. to 1:00 p.m. on Saturdays, was lawful and that Republic Act No. 1880 did not mandate overtime pay for such Saturday work.

ISSUE

The primary issues were: (1) whether the CIR had jurisdiction over the claim, and (2) whether the union members were entitled to overtime pay for work rendered on Saturdays during the period in question.

RULING

The Supreme Court upheld the CIR’s jurisdiction but reversed its decision on the merits, dismissing the claim for overtime pay. On jurisdiction, the Court ruled it was settled that a claim for overtime pay, when coupled with an allegation of an existing employer-employee relationship and a labor dispute likely to cause a strike, falls within the exclusive jurisdiction of the CIR.
On the merits, the Court analyzed the applicable laws. Republic Act No. 1880, applying the provisions of the Administrative Code to government-owned corporations, prescribed a work schedule of eight hours a day for five days a week, or a total of forty hours, as a minimum requirement. Executive Order No. 251 implemented this by setting office hours from Monday to Friday. The subsequent collective bargaining contract stipulated a workweek of seven hours daily from Monday to Friday (totaling 35 hours) and five hours on Saturday. The union argued that under the law, Saturday was a non-working day, making Saturday work overtime.
The Court rejected this argument. It held that neither the law nor the executive order declared Saturday a non-working day. The forty-hour weekly minimum was not met by working only thirty-five hours from Monday to Friday. Therefore, requiring work on Saturday for up to five hours was necessary to fulfill the statutory minimum and did not constitute overtime. The contract itself recognized this necessity. The Court further noted that any overtime already paid for an eighth hour on weekdays could not be counted toward the forty-hour minimum. The company’s later resolution granting overtime for Saturday work was a concession that could not be imposed retroactively. The CIR’s finding of discrimination compared to security guards was unsupported by evidence of identical working conditions and was immaterial to the legal issue. Consequently, the claim for differential overtime pay was dismissed.
