G.R. No. 80587 February 8, 1989
WENPHIL CORPORATION, petitioner, vs. NATIONAL LABOR RELATIONS COMMISSION AND ROBERTO MALLARE, respondents.

FACTS

Private respondent Roberto Mallare was employed by petitioner Wenphil Corporation. On May 20, 1985, Mallare was involved in a physical altercation with a co-employee. The following day, he was suspended and, later that same afternoon, dismissed via a memorandum from the Operations Manager citing company rules. The notice of dismissal was served on May 25, 1985. Mallare filed a complaint for illegal dismissal. The Labor Arbiter dismissed the complaint, finding the dismissal valid. On appeal, the National Labor Relations Commission (NLRC) reversed the Arbiter, ordering Mallare’s reinstatement with one year of backwages. The NLRC found the dismissal procedurally infirm. Wenphil elevated the case to the Supreme Court via certiorari, arguing the NLRC committed grave abuse of discretion.
Petitioner’s defense rested on its Personnel Manual. It alleged Mallare committed serious misconduct and insubordination by defying a manager after the incident. The manual stated that for offenses punishable by a penalty higher than a 15-day suspension, an investigation board would be convened only “upon the request of the erring employee.” Petitioner contended that since Mallare did not request an investigation and was defiant when asked to explain, he effectively waived his right to due process, making his immediate dismissal valid.

ISSUE

Whether the dismissal of private respondent Roberto Mallare was valid despite the alleged waiver of his right to an investigation under the company’s Personnel Manual.

RULING

The Supreme Court ruled that the dismissal was for a just cause but was illegally executed due to denial of due process. The Court found Mallare guilty of serious misconduct and insubordination based on the factual findings, warranting dismissal. However, the employer failed to comply with the mandatory procedural requirements for termination.
The legal logic is clear: the constitutional and statutory guarantee of security of tenure requires dismissal to be both for a just or authorized cause and effected after due process. The Implementing Rules of the Labor Code mandate twin notices and a hearing opportunity before termination. The company’s Personnel Manual provision, which conditions an investigation solely on the employee’s request, cannot override this legal mandate. Such a stipulation effectively allows an employer to evade its statutory duty to conduct a hearing or investigation, thereby depriving the employee of due process. A waiver of this fundamental right cannot be presumed from mere defiance immediately after a heated incident. Due process is a duty of the employer, not a mere right of the employee that can be unilaterally waived by contract or inferred from conduct during a confrontation.
Consequently, while the dismissal was substantively justified, the procedural defect rendered it illegal. The Court modified the NLRC decision. Reinstatement and backwages were denied because the cause for dismissal existed. However, recognizing the procedural lapse, the Court ordered petitioner to pay private respondent an indemnity of One Thousand Pesos (P1,000.00) for violating his right to due process. The decision underscores that compliance with due process is an indispensable requirement separate from the existence of a just cause for termination.
