I. Introduction and Governing Framework
The right to strike and the correlative right to lockout are constitutionally recognized modes of collective action, but they are not absolute. They are statutory privileges strictly regulated by the Labor Code of the Philippines (Presidential Decree No. 442, as amended), its Implementing Rules, and pertinent jurisprudence. The primary objective of the law is to establish a delicate balance between the workers’ right to collective action and the state’s interest in promoting industrial peace, protecting the public welfare, and ensuring the orderly settlement of labor disputes.
II. Definition and Nature of a Strike
A strike is any temporary stoppage of work by the concerted action of employees as a result of an industrial or labor dispute. It is a weapon of last resort to be used only after all reasonable means of settlement have been exhausted. The law distinguishes between economic strikes (involving terms and conditions of employment like wages, benefits) and unfair labor practice (ULP) strikes (protesting an employer’s ULP as defined under Article 248 of the Labor Code).
III. Definition and Nature of a Lockout
A lockout is the temporary refusal of an employer to furnish work as a result of an industrial or labor dispute. It is the employer’s counterpart to a strike, utilized to bring economic pressure upon employees to accept the employer’s terms. Like a strike, it is subject to stringent procedural requirements.
IV. Prerequisites for a Valid Strike or Lockout (The 30-Day Cooling-Off Period and Strike Vote)
No strike or lockout may be declared without compliance with mandatory procedural steps:
a. Notice of Strike or Lockout: A written notice must be filed with the National Conciliation and Mediation Board (NCMB) at least 30 days (for ULP) or 15 days (for bargaining deadlock) before the intended date of action. This initiates a cooling-off period where no strike or lockout may lawfully take place, allowing for conciliation.
b. Strike Vote Report: For strikes, a separate report must be submitted to the NCMB at least seven days before the intended strike date, showing that a majority of the union members in a meeting specifically called for the purpose voted in favor of the strike by secret ballot.
V. Prohibited Acts and Unlawful Strikes/Lockouts
A strike or lockout may be declared illegal on substantive or procedural grounds. Key prohibitions include:
a. Declaring a strike or lockout without complying with the mandatory notices and cooling-off periods.
b. Declaring a strike or lockout based on non-strikeable issues (e.g., inter-union disputes, issues already subject of arbitration).
c. Engaging in violence, coercion, intimidation, or acts of sabotage in the course of the strike or lockout.
d. Declaring a strike or lockout after the Secretary of Labor has assumed jurisdiction over the dispute or after a certification for voluntary arbitration.
VI. Effects of a Legal Strike
Upon the lawful declaration of a strike, the employer is generally prohibited from hiring replacement workers for strikers engaged in a ULP strike. The employment relationship is merely suspended. Strikers retain their employee status and, upon the strike’s conclusion, are entitled to reinstatement, generally without loss of seniority rights, provided they make an unconditional offer to return to work.
VII. Effects of an Illegal Strike
Participants in an illegal strike may be subject to disciplinary action, including dismissal for those who committed illegal acts or who are found to be union leaders who knowingly participated in the illegal action. The union may lose its legal personality. The employer is not obligated to reinstate dismissed employees, except where the dismissal is found to be unjustified.
VIII. Assumption of Jurisdiction and Certification Power
The Secretary of Labor possesses the extraordinary power to assume jurisdiction over a labor dispute causing or likely to cause a strike or lockout in an industry indispensable to the national interest, or to certify it to the National Labor Relations Commission (NLRC) for compulsory arbitration. Once assumed or certified, any ongoing strike or lockout must cease, and workers must return to work within a specified period. Disobedience is unlawful and may result in loss of employment.
IX. Practical Remedies
Upon threat or occurrence of a strike or lockout, immediate action is critical. First, verify the union’s compliance with all procedural requisites (Notice, Strike Vote Report) by coordinating with the NCMB regional branch. If procedural defects exist, file a petition to declare the strike illegal with the NLRC, seeking a restraining order or injunction. For strikes involving violence, obstruction, or trespass, seek police assistance through a clearance from the DOLE and consider filing criminal complaints for specific offenses. If the dispute severely impacts operations or falls within a nationally critical industry, prepare a petition for the Secretary of Labor to assume jurisdiction, emphasizing the grave prejudice to the national interest. Concurrently, continue participating in good faith in any NCMB-conciliated negotiations to demonstrate reasonableness and potentially mitigate liability. Document all incidents, communications, and violations meticulously, as this evidence is paramount in any subsequent illegal strike case or unfair labor practice complaint. For a defensive lockout, ensure strict adherence to the mirror procedural requirements and base the action on a genuine, substantiated ground such as imminent substantial loss or a ULP committed by the union.
