Rosario T. Mamerto v. Minister of Labor

Summary

Twenty-eight employees of Lucky Garments Manufacturing Company filed an illegal dismissal complaint, alleging termination due to union activities constituting unfair labor practice. The company sought clearance to dismiss employees for various causes including participation in illegal sit-down strike, unauthorized absences, rule violations, and failure to meet training standards. The Regional Director dismissed the complaint after petitioners failed to submit required position papers and instead sought compulsory arbitration. The Deputy Minister affirmed on appeal, finding substantial evidence of economic sabotage and illegal strike activities. The Supreme Court dismissed the certiorari petition, ruling there was no denial of due process as petitioners had adequate opportunity to be heard, and the case did not require compulsory arbitration as it involved no intricate legal questions. The Court found the dismissals were supported by substantial evidence and petitioners failed to prove wrongful termination, upholding the labor tribunals' findings of dismissal for just cause.
