When Company Rules Clash With Labor Rights Reinstatement Despite Misconduct

Philippine Supreme Court rules on reinstatement without backwages when both employer and workers are at fault in labor dispute.


The Supreme Court's 2011 decision in Automotive Engine Rebuilders, Inc. v. Progresibong Unyon Ng Mga Manggagawa sa AER (G.R. No. 160138) illustrates a central tension in Philippine labor law: when both employer and employees commit wrongs in a labor dispute, what remedy should the law provide? The case involved a company that suspended and dismissed workers amid a union organizing drive, and workers who staged a walkout and picket in protest. The Court's ruling—ordering reinstatement of all workers but denying backwages—offers important guidance on how labor tribunals balance company rules against statutory protections.

The Dispute

Automotive Engine Rebuilders, Inc. (AER) had operated for over 35 years when its rank-and-file employees formed a union in 1998. The day after the union filed a petition for certification election, AER required all employees to undergo drug testing—the company's first such test in its decades of operation. Seven employees tested positive and were suspended under the Employee's Handbook, which prohibited reporting to work under the influence of drugs.

Five of the suspended employees were not allowed back unless they submitted medical certificates attesting they were fit to work. While they were securing these certificates, AER charged them with insubordination and absence without leave. Meanwhile, the union, suspecting AER was moving machinery to another site in a "runaway shop" scheme, staged a walkout and picket. AER responded by dismissing 18 employees for illegal strike and other offenses.

The Issue

The central question before the Supreme Court was whether the Court of Appeals erred in ordering the reinstatement of all complaining employees without backwages, including those who tested positive for illegal drugs and those who participated in the walkout.

The Ruling

The Supreme Court affirmed the reinstatement order but denied backwages. The Court found that neither party came to court with "clean hands"—both were in pari delicto (in equal fault).

On the drug testing and suspension. The Court found AER's conduct suspicious. The drug test was implemented immediately after the union organized, and AER failed to prove it was a regular company practice. More importantly, AER did not show that the drug test was conducted by an authorized drug testing center or that both the screening and confirmatory tests required by law were performed. The Court noted that drug testing under R.A. No. 9165 must be done by authorized centers and must employ both screening and confirmatory methods. The Court also cited Nacague v. Sulpicio Lines for the principle that when the alleged valid cause for termination is not clearly proven, the law considers the matter an illegal dismissal.

On the walkout and strike. The Court acknowledged the workers were also at fault. They staged a work slowdown, walked out, and forced their way into company premises. However, the Court noted the walkout lasted only a day, no injuries occurred, and no violence was reported. Citing Tupas Local Chapter No. 979 v. NLRC and PBM Employees Organization v. PBM Co., Inc., the Court reiterated that a mere finding of an illegal strike does not automatically warrant dismissal—a penalty less punitive would suffice where workers acted out of genuine belief that management committed unfair labor practice.

On the remedy. Because both parties were at fault, the Court applied the in pari delicto doctrine, citing Philippines Inter-Fashion, Inc. v. NLRC. This doctrine warrants restoration of the status quo ante—bringing the parties back to their positions before the controversy. Reinstatement achieves this; backwages would not, since the principle of "no work, no pay" applies where the strike was illegal.

Practical Takeaways

  • Company rules do not override statutory due process. Even where an employee handbook prohibits certain conduct, employers must observe procedural and substantive due process before imposing penalties.
  • Drug testing has strict legal requirements. Under R.A. No. 9165, drug tests must be conducted by authorized centers and must include both screening and confirmatory tests. A positive result from an unaccredited center or a screening test alone may not justify dismissal.
  • Timing matters. A drug test imposed immediately after union organizing may be viewed as anti-union discrimination, especially if it was not a regular company practice.
  • Illegal strikes do not automatically justify dismissal. The penalty must be proportionate to the offense. A one-day walkout without violence may warrant a lesser penalty than dismissal.
  • When both sides are at fault, reinstatement without backwages may be the remedy. The in pari delicto doctrine restores the status quo but does not reward either party with monetary damages.
