Union Rights in the Philippines: Organizing, CBAs and Strike Procedure

Quick answers

Who may join or form a union?

The right to self-organization is guaranteed by Article XIII, Section 3 of the 1987 Constitution and implemented by Article 253 [243], which covers all persons employed in commercial, industrial and agricultural enterprises and in religious, charitable, medical and educational institutions, whether operating for profit or not. Article 257 [246] makes it unlawful to restrain, coerce, discriminate against or unduly interfere with the exercise of that right.

• Managerial employees are not eligible to join, assist or form any labor organization (Article 255 [245]).
• Supervisory employees may not join the rank-and-file bargaining unit but may form or join separate unions of their own (Article 255 [245]).
• Confidential employees are excluded by jurisprudence rather than by statute, under the doctrine of necessary implication — but only those who assist and act in a confidential capacity to persons who formulate and effectuate management policies in the field of labor relations. Mere access to business-confidential data is not enough (San Miguel Corporation Supervisors and Exempt Union v. Laguesma, G.R. No. 110399, 15 August 1997).
• Government employees may form associations, and employees of government corporations established under the Corporation Code may organize and bargain collectively (Article 254 [244]).

How do we register, and does mixed membership kill the union?

An independent union registers with the DOLE Regional Office or the Bureau of Labor Relations under Article 240 [234], which requires the names of members comprising at least 20 percent of all employees in the bargaining unit, together with the registration fee, the officers’ names and addresses, minutes of the organizational meetings and list of participants, annual financial reports where applicable, and four copies of the constitution and by-laws with the minutes of ratification.

A federation or national union may instead create a local chapter by issuing a charter certificate under Article 241 [234-A]. A chartered local acquires legal personality for the purpose of filing a petition for certification election from the date the charter certificate is issued, and full rights once it submits its officers’ names and its constitution and by-laws. Notably, the 20 percent requirement applies to independent unions, not to chartered locals.

On mixed membership: the commingling of supervisory and rank-and-file members does not automatically divest a union of legitimacy (Republic v. Kawashima Textile Mfg. Phils., Inc., G.R. No. 160352, 23 July 2008). This is now codified in Article 256 [245-A] — the ineligible employees are simply deemed removed from the membership list. And under Article 246 [238-A], a petition for cancellation of registration does not suspend certification election proceedings nor prevent a petition from being filed. Registration may be cancelled only on limited grounds: misrepresentation or fraud in the adoption or ratification of the constitution and by-laws or in the election of officers, or voluntary dissolution.

How is the bargaining agent chosen?

By certification election, conducted and supervised by a Med-Arbiter of the DOLE Regional Office.

• Unorganized establishment (no certified bargaining agent) — the election is conducted automatically upon the filing of a petition by any legitimate labor organization, including a federation that has chartered a local, or the chartered local itself. No 25 percent support requirement applies (Article 269 [257]).
• Organized establishment — the petition must be verified, filed within the 60-day freedom period before the CBA expires, and supported by the written consent of at least 25 percent of all employees in the bargaining unit (Article 268 [256]).
• The double-majority rule — for a valid election, a majority of all eligible voters must actually cast votes; the union receiving a majority of the valid votes cast is certified as exclusive bargaining agent (Article 268 [256]). “No union” is a choice on the ballot, and a run-off follows where no choice obtains a majority from three or more options.
• The employer is a bystander. It cannot oppose the petition; its role is limited to being notified and submitting the list of employees at the pre-election conference (Article 271 [258-A]).

Outside the freedom period, the contract bar rule in Article 238 [232] prevents any petition that would disturb the administration of a duly registered existing CBA.

How long does a CBA last, and when can it be renegotiated?

Article 265 [253-A] splits the CBA in two:

• The representation aspect — who the bargaining agent is — runs for five years and cannot be shortened. No petition questioning majority status may be entertained outside the 60-day period immediately before the end of that five-year term. That window is the freedom period.
• All other provisions, including the economic terms, must be renegotiated not later than three years after execution.
• Retroactivity — an agreement on those other provisions concluded within six months of the expiry of the three-year term retroacts to the day after that date. Beyond six months, retroactivity is whatever the parties agree.

The duty to bargain (Article 263 [252]) is the mutual obligation to meet promptly and in good faith on wages, hours and other terms and conditions of employment, and to execute the agreement reached — but it does not compel either party to agree to a proposal or make a concession. Under Article 261 [250] the other party must reply to written proposals within 10 calendar days, and either side may request NCMB conciliation. Under Article 264 [253] neither party may terminate or modify the CBA during its lifetime; the status quo continues after the 60-day notice period and until a new agreement is reached.

Do non-members pay anything if they take CBA benefits?

Yes — an agency fee. Under the proviso to Article 259(e) [248(e)], employees in the bargaining unit who are not members of the recognised bargaining agent may be assessed a reasonable fee equivalent to the dues and other fees paid by members, if they accept the benefits under the CBA. Because liability arises from accepting the benefit rather than from contract, no individual written authorization is required for the agency fee, unlike ordinary union dues under Article 250 [241]. The amount may not exceed union dues.

What goes to the grievance machinery, and what to a Voluntary Arbitrator?

Parties to a CBA must establish a grievance machinery for disputes arising from the interpretation or implementation of the CBA and from the interpretation or enforcement of company personnel policies. Under Article 273 [260], grievances not settled within seven calendar days from submission are automatically referred to voluntary arbitration.

Article 274 [261] gives Voluntary Arbitrators original and exclusive jurisdiction over those unresolved grievances and over gross violations of the CBA — defined as flagrant or malicious refusal to comply with the economic provisions of the agreement. A CBA violation that is not gross is a grievance, not an unfair labor practice, and it is not strikeable. Under Article 275 [262], all other labor disputes including ULP and bargaining deadlocks may go to a Voluntary Arbitrator only upon the agreement of both parties — mutual consent is jurisdictional. A VA award becomes final and executory after 10 calendar days from receipt (Article 276 [262-A]).

What exactly does a lawful strike require?

This is where unions most often lose. There are only two lawful grounds for a strike: unfair labor practice and collective bargaining deadlock. The sequence under Article 278 [263] is cumulative — each step must be completed, in order:

1. File a notice of strike with the NCMB regional branch.
2. Observe the cooling-off period — 30 days for a bargaining deadlock, 15 days for unfair labor practice — during which NCMB conciliation is mandatory.
3. Take the strike vote by secret ballot. The decision to strike must be approved by a majority of the total union membership in the bargaining unit concerned — not a majority of those present.
4. Submit the strike vote results to the Department at least seven days before the intended strike.
5. Observe the seven-day strike ban, which runs from submission of the results and is separate from, and additional to, the cooling-off period.

Union busting — the dismissal of union officers duly elected under the union’s constitution and by-laws, where the existence of the union is threatened — waives the cooling-off period only. The notice of strike, the strike vote and the seven-day strike ban all remain mandatory.

Not strikeable at all: inter-union and intra-union disputes, violations of labor standards, issues already submitted to voluntary or compulsory arbitration, and CBA violations that are not gross.

What happens to members and officers if a strike is declared illegal?

The distinction in Article 279(a) [264(a)] is precise and worth memorising:

• A union officer who knowingly participates in an illegal strike may be declared to have lost his employment status — participation alone suffices.
• An ordinary worker or union member may lose employment status only where he knowingly participates in the commission of illegal acts during the strike.
• Mere participation in a lawful strike is not a ground for termination, for anyone.

Liability is individual, not collective — substantial evidence must identify the specific illegal act and the specific person who committed it. Article 279(e) [264(e)] is the rule most often violated in practice: no person engaged in picketing shall commit any act of violence, coercion or intimidation, obstruct the free ingress to or egress from the employer’s premises for lawful purposes, or obstruct public thoroughfares. Stationary pickets and permanent blockades are prohibited, as is employing or acting as a strike-breaker.

What is assumption of jurisdiction, and which industries does it cover?

Under Article 278(g) [263(g)], where a labor dispute causes or is likely to cause a strike or lockout in an industry indispensable to the national interest, the Secretary of Labor may assume jurisdiction and decide it, or certify it to the NLRC for compulsory arbitration. Either step automatically enjoins the intended or impending strike or lockout. If a strike has already begun, all striking employees must immediately return to work and the employer must resume operations and readmit them under the same terms and conditions prevailing before the strike. The return-to-work order is immediately executory, and defying it is a prohibited activity that exposes strikers to loss of employment status.

DOLE Department Order No. 40-H-13 (21 October 2013) narrowed what had been open-ended discretion into a defined list. The industries recognised as indispensable to the national interest are the hospital sector, the electric power industry, water supply services (excluding small water supply services such as bottling and refilling stations), air traffic control, and such other industries as may be recommended by the National Tripartite Industrial Peace Council. Hospitals must maintain a skeletal medical staff during a labor dispute.

One provision worth knowing during a strike: under Article 280 [265], the NCMB may conduct improved offer balloting by secret ballot on the employer’s improved offer, and if a majority of union members vote to accept it, the strikers return to work on signing of the agreement.

What has changed recently for union rights?

The strike mechanics themselves have not been amended — Articles 278 [263] and 279 [264] stand as amended by Republic Act No. 6715, and the last substantive regulatory change was DO 40-H-13 in 2013. What has moved is enforcement and civil liberties:

• Executive Order No. 23, series of 2023 (30 April 2023) reinforces freedom of association and the right to organize, and creates an Inter-Agency Committee reporting to the President — chaired by the Executive Secretary with DOLE as vice-chair and secretariat — to expedite the investigation, prosecution and resolution of violations. It is grounded in the Constitution and ILO Convention No. 87.
• Executive Order No. 97 (2025) adopts Omnibus Guidelines on the Exercise of Freedom of Association and Civil Liberties, directing DOLE, DOJ, DND, DTI, the AFP, the PNP and the NSC to embed them in training and operations, with DOLE monitoring compliance through the National Tripartite Industrial Peace Council.
• Security of tenure and anti-endo legislation remains pending, not enacted. The consolidated Security of Tenure Bill of the 17th Congress was vetoed in 2019; a successor measure was refiled in the 20th Congress in July 2025 and has not passed. Nothing in that area is currently law.
