G.R. No. 123226 May 21, 1998.
Bonifacio Anino, Ricardo Navarro, Henry Filoteo, David Daugdaug, Edgardo Ceredon and Alan Baladya, petitioners, vs. National Labor Relations Commission, Hinatuan Mining Corporation and Federico B. Ganigan, respondents.

FACTS

Petitioners were supervisory employees of respondent Hinatuan Mining Corporation (HMC). They were active leaders and members of the Hinatuan Mining Supervisory Union (HIMSU), which was organized and registered in September 1993. The union formally notified HMC of its existence and submitted collective bargaining proposals in November 1993. HMC allegedly ignored these proposals, leading the union to file an unfair labor practice case on May 13, 1994. On June 16, 1994, petitioners were dismissed from service. HMC claimed the dismissal was due to retrenchment implemented to prevent further losses, affecting both rank-and-file and supervisory employees. Petitioners accepted and received separation pay equivalent to one month’s pay for every year of service and executed corresponding waivers and quitclaims. The Labor Arbiter found the retrenchment unsubstantiated and declared the dismissal illegal, ordering reinstatement with back wages but dismissing the unfair labor practice and damages claims. The National Labor Relations Commission (NLRC) reversed this decision, vacating the finding of illegal dismissal and denying reinstatement. The NLRC based its reversal on petitioners’ acceptance of retrenchment benefits after two months and on its judicial notice that the mining industry in Mindanao suffered economic difficulties.

ISSUE

Were petitioners validly retrenched?

RULING

No. The Supreme Court ruled that petitioners were not validly retrenched. The Court adhered to the doctrine in Lopez Sugar Corporation vs. Federation of Free Workers, which requires employers to prove with substantial evidence the following requisites to justify retrenchment: (1) that the retrenchment is reasonably necessary and likely to prevent business losses; (2) that the employer served written notice both to the employees and the Department of Labor and Employment at least one month prior to the intended date of retrenchment; (3) that the employer paid separation pay equivalent to one month pay or at least one-half month pay for every year of service, whichever is higher; (4) that the employer exercised good faith in selecting employees to be retrenched; and (5) that the employer used fair and reasonable criteria in the selection. The Court found that HMC failed to discharge this burden of proof. The NLRC’s reliance on “judicial notice” of industry difficulties was insufficient, as retrenchment must be justified by concrete and substantial proof of actual or imminent financial losses specific to the employer. Furthermore, the waivers and quitclaims signed by petitioners, who received benefits merely equivalent to the legal minimum, were invalid as they were executed after their illegal dismissal and did not constitute a voluntary and reasonable settlement. The NLRC committed grave abuse of discretion in reversing the Labor Arbiter’s decision. The Supreme Court granted the petition, reinstated the Labor Arbiter’s decision declaring the dismissal illegal, and ordered petitioners’ reinstatement with full back wages.
