Article 278 [263] ng Labor Code: Strike, picketing at lockout

(a) It is the policy of the State to encourage free trade unionism and free collective bargaining.

(b) Workers shall have the right to engage in concerted activities for purposes of collective bargaining or for their mutual benefit and protection. The right of legitimate labor organizations to strike and picket and of employers to lockout, consistent with the national interest, shall continue to be recognized and respected. However, no labor union may strike and no employer may declare a lockout on grounds involving inter-union and intra-union disputes.

(c) In cases of bargaining deadlocks, the duly certified or recognized bargaining agent may file a notice of strike or the employer may file a notice of lockout with the Ministry at least 30 days before the intended date thereof. In cases of unfair labor practice, the period of notice shall be 15 days and in the absence of a duly certified or recognized bargaining agent, the notice of strike may be filed by any legitimate labor organization in behalf of its members. However, in case of dismissal from employment of union officers duly elected in accordance with the union constitution and by-laws, which may constitute union busting where the existence of the union is threatened, the 15-day cooling-off period shall not apply and the union may take action immediately.

(d) The notice must be in accordance with such implementing rules and regulations as the Minister of Labor and Employment may promulgate.

(e) During the cooling-off period, it shall be the duty of the Ministry to exert all efforts at mediation and conciliation to effect a voluntary settlement. Should the dispute remain unsettled until the lapse of the requisite number of days from the mandatory filing of the notice, the labor union may strike or the employer may declare a lockout.

(f) A decision to declare a strike must be approved by a majority of the total union membership in the bargaining unit concerned, obtained by secret ballot in meetings or referenda called for that purpose. A decision to declare a lockout must be approved by a majority of the board of directors of the corporation or association or of the partners in a partnership, obtained by secret ballot in a meeting called for that purpose. The decision shall be valid for the duration of the dispute based on substantially the same grounds considered when the strike or lockout vote was taken. The Ministry may, at its own initiative or upon the request of any affected party, supervise the conduct of the secret balloting. In every case, the union or the employer shall furnish the Ministry the results of the voting at least seven days before the intended strike or lockout, subject to the cooling-off period herein provided.

(g) When, in his opinion, there exists a labor dispute causing or likely to cause a strike or lockout in an industry indispensable to the national interest, the Secretary of Labor and Employment may assume jurisdiction over the dispute and decide it or certify the same to the Commission for compulsory arbitration. Such assumption or certification shall have the effect of automatically enjoining the intended or impending strike or lockout as specified in the assumption or certification order. If one has already taken place at the time of assumption or certification, all striking or locked out employees shall immediately return to work and the employer shall immediately resume operations and readmit all workers under the same terms and conditions prevailing before the strike or lockout. The Secretary of Labor and Employment or the Commission may seek the assistance of law enforcement agencies to ensure compliance with this provision as well as with such orders as he may issue to enforce the same.

In line with the national concern for and the highest respect accorded to the right of patients to life and health, strikes and lockouts in hospitals, clinics and similar medical institutions shall, to every extent possible, be avoided, and all serious efforts, not only by labor and management but government as well, be exhausted to substantially minimize, if not prevent, their adverse effects on such life and health, through the exercise, however legitimate, by labor of its right to strike and by management to lockout. In labor disputes adversely affecting the continued operation of such hospitals, clinics or medical institutions, it shall be the duty of the striking union or locking-out employer to provide and maintain an effective skeletal workforce of medical and other health personnel, whose movement and services shall be unhampered and unrestricted, as are necessary to insure the proper and adequate protection of the life and health of its patients, most especially emergency cases, for the duration of the strike or lockout. In such cases, therefore, the Secretary of Labor and Employment may immediately assume, within twenty four (24) hours from knowledge of the occurrence of such a strike or lockout, jurisdiction over the same or certify it to the Commission for compulsory arbitration. For this purpose, the contending parties are strictly enjoined to comply with such orders, prohibitions and/or injunctions as are issued by the Secretary of Labor and Employment or the Commission, under pain of immediate disciplinary action, including dismissal or loss of employment status or payment by the locking-out employer of backwages, damages and other affirmative relief, even criminal prosecution against either or both of them.

The foregoing notwithstanding, the President of the Philippines shall not be precluded from determining the industries that, in his opinion, are indispensable to the national interest, and from intervening at any time and assuming jurisdiction over any such labor dispute in order to settle or terminate the same.

(h) Before or at any stage of the compulsory arbitration process, the parties may opt to submit their dispute to voluntary arbitration.

(i) The Secretary of Labor and Employment, the Commission or the voluntary arbitrator or panel of voluntary arbitrators shall decide or resolve the dispute within thirty (30) calendar days from the date of the assumption of jurisdiction or the certification or submission of the dispute, as the case may be. The decision of the President, the Secretary of Labor and Employment, the Commission or the voluntary arbitrator shall be final and executory ten (10) calendar days after receipt thereof by the parties.
