Collective Bargaining Agreement in the Philippines: Negotiation, Coverage and Enforcement

A union does not get better wages, benefits or job security just by winning a certification election. It gets the legal right to sit across the table from management and negotiate those things — and the employer, in turn, gets a legal duty to negotiate back in good faith. What happens in between, and what happens when either side refuses to negotiate honestly, is where most collective bargaining disputes in the Philippines actually arise.

Employees frequently assume a certified union automatically produces a new contract with better terms. Employers frequently assume that stalling, delaying, or disputing a union’s legitimacy is a low-risk way to avoid conceding anything. Philippine labor law rejects both assumptions. A collective bargaining agreement (CBA) is the product of a legally regulated process with defined timelines, mandatory good-faith conduct, and real consequences — including unfair labor practice liability — for either side that abuses it.

This guide explains what a CBA is, who has the right to negotiate one, the legal procedure both sides must follow, what a valid CBA must contain, how long it lasts, and what happens when negotiations break down.

Direct Answer

A Collective Bargaining Agreement is the negotiated contract between an employer and the sole and exclusive bargaining agent of a specific bargaining unit, governing wages, hours and other terms and conditions of employment for that unit. Once a union is certified, both the employer and the union have a mandatory duty under Article 251 of the Labor Code to bargain collectively in good faith^[1] — to meet, exchange written proposals, and respond to a counter-proposal within ten calendar days of receiving one.^[2]

A CBA’s representation aspect runs for five years and cannot be challenged by a rival union except during the 60-day “freedom period” immediately before that five-year term expires. All other provisions of the agreement — wages, benefits, working conditions — must be renegotiated not later than three years after execution, under Article 253-A.^[3] A party that refuses to bargain, engages in surface bargaining, or suspends negotiations without a valid legal basis commits an unfair labor practice and risks having a court or the National Labor Relations Commission (NLRC) impose the other side’s draft agreement.^[4][5][6]

Key Takeaways

A CBA covers only the specific bargaining unit represented by the certified or voluntarily recognized sole and exclusive bargaining agent (SEBA) — not every employee of the company.
Once a union has bargaining status, both employer and union have a mandatory legal duty to bargain in good faith, not merely a moral or practical incentive to do so.
The law sets actual deadlines: a party that receives a written bargaining proposal must reply within 10 calendar days.
A CBA must be ratified by the majority of the bargaining unit and registered with DOLE within 30 days of execution to enjoy full legal effect.
The representation aspect of a CBA lasts five years; a rival union may only challenge representation status during the 60-day freedom period before that term ends.
All other CBA provisions (wages, benefits, working conditions) must be renegotiated within three years of the CBA’s execution.
Refusing to bargain, stalling through “empty gestures,” or suspending negotiations without a legitimate basis is an unfair labor practice — and courts have imposed the other party’s entire draft CBA as a consequence.
When an existing CBA expires before a new one is signed, its terms generally continue on a hold-over basis until a new agreement is reached; employees do not lose their existing benefits simply because the old contract’s date has passed.

What Is a Collective Bargaining Agreement?

A Collective Bargaining Agreement is a written contract negotiated between an employer and the union recognized as the sole and exclusive bargaining agent (SEBA) of an appropriate bargaining unit. It fixes the wages, hours of work, and other terms and conditions of employment applicable to the employees in that unit for the life of the agreement.

Unlike an individual employment contract, a CBA is not negotiated employee-by-employee. It is negotiated once, by the union acting on behalf of everyone in the bargaining unit, and its terms then apply uniformly to every covered employee — including those who did not vote for the union and, in many cases, even those who are not union members, subject to the union’s own constitution and any applicable agency-fee arrangement.

The right to collective bargaining flows from the constitutional guarantee of self-organization and is implemented through Book Five (Labor Relations) of the Labor Code. It exists alongside, and is enforced separately from, an employee’s individual employment contract and general labor standards.

Who Can Negotiate: The Bargaining Unit and the Exclusive Bargaining Agent

Not every union in a company can demand to bargain, and not every employee is covered by a CBA once one exists. Two concepts control this:

The bargaining unit

A bargaining unit is the specific, legally appropriate grouping of employees who share a substantial community of interest — similar work, similar pay structures, similar interests — and who will be governed by the resulting CBA. Rank-and-file employees and supervisory employees are generally treated as separate bargaining units and may not belong to the same labor organization, since their interests can directly conflict (a supervisor may be called on to discipline a rank-and-file subordinate).

The sole and exclusive bargaining agent (SEBA)

Only one union may hold bargaining rights for a given unit at a time. That status is normally established through a certification election supervised by DOLE’s Bureau of Labor Relations, in which employees in the unit vote for their preferred union (or no union). A union that wins is certified as the SEBA and gains the exclusive right — and the employer’s corresponding duty — to negotiate a CBA on the unit’s behalf. In workplaces with only one legitimate union and no competing claim, the SEBA may instead be recognized through a simplified process without a formal election.

Because SEBA status is exclusive, an employer cannot lawfully negotiate a separate, parallel arrangement with a different group purporting to represent the same employees while a certified union already holds bargaining rights, and a rival union generally cannot displace the incumbent except through the certification-election process during the freedom period discussed below.

The Legal Procedure for Negotiating a CBA

Article 250 of the Labor Code sets out a concrete procedure, not just a general aspiration to negotiate:

Written notice and proposal. The party that wants to negotiate — usually the union, whether for an initial CBA or a renegotiation — serves a written notice with its proposals on the other party.
Ten-day reply. The receiving party must reply in writing not later than ten calendar days from receipt. Silence, or an answer that does not actually engage with the proposal, does not satisfy this duty.
Conference. If differences arise, either party may request a conference, which must begin within ten calendar days of the request.
Conciliation. If the parties cannot agree, either may seek the assistance of the National Conciliation and Mediation Board (NCMB), which convenes conciliation meetings to help the parties reach an agreement.
Deadlock and industrial action. If conciliation fails, the union may resort to lawful concerted activities (such as a strike, subject to separate notice and cooling-off requirements), or the parties may submit the dispute to voluntary arbitration or, in specific cases, to the Secretary of Labor for assumption of jurisdiction.

The controlling legal standard throughout this process is good faith. The Labor Code does not require either side to agree to any particular proposal or to make concessions, but it does require a genuine, good-faith effort to reach an agreement — not merely going through the motions.

Common Problems: Surface Bargaining and Refusal to Bargain

Philippine jurisprudence recognizes that a party can technically show up to the bargaining table while still violating the duty to bargain. Courts and labor arbiters commonly treat the following as evidence of bad faith, sometimes called “surface bargaining”:

Never submitting a counter-proposal despite repeated requests, or missing the 10-day reply window without justification.
Requesting repeated postponements of scheduled negotiation sessions, or simply failing to send a representative.
Disputing the union’s legal existence or legitimacy as a pretext to avoid negotiating at all, rather than pursuing that challenge through the proper legal process.
Suspending negotiations because a rival union filed a certification petition that does not actually fall within the valid freedom period or otherwise fails to raise a legitimate representation question.
Making only illusory or clearly unacceptable counter-offers designed to stall rather than to reach agreement.
Retaliating against union officers — through reassignment, discipline or dismissal — in a manner and timing that coincides with active negotiations.

None of these signs is automatically fatal on its own, but the “totality of conduct” — how a party behaved across the entire negotiation, not any single incident in isolation — is what Philippine courts use to decide whether a refusal-to-bargain unfair labor practice occurred.

What a CBA Must Contain and How It Is Registered

A CBA typically covers, at minimum: wage rates and wage adjustments, hours of work and overtime rules, leave benefits beyond the statutory minimum, grievance machinery, a no-strike/no-lockout clause, union security provisions (such as a maintenance-of-membership or agency-fee clause, where applicable), and the agreement’s term.

Execution alone does not make a CBA fully effective. Under Article 231, the parties must, within 30 days of execution, submit the signed agreement to the DOLE Bureau of Labor Relations or the appropriate DOLE Regional Office for registration, together with:

Verified proof that the CBA was posted in at least two conspicuous places in the workplace for at least five days; and
Proof that the agreement was ratified by the majority of all employees in the bargaining unit, not merely by union members or union officers.

DOLE is required to act on a properly documented application within a short period after receipt. Registration matters in practice: a registered CBA carries a presumption of regularity and gives the agreement stronger legal footing in the event of a later dispute over its terms or validity.

CBA Term, Renegotiation and the Freedom Period

Article 253-A creates two different clocks that run at the same time from execution, and confusing them is one of the most common CBA disputes:

Aspect	Duration	What It Controls
Representation aspect	5 years	Which union, if any, holds exclusive bargaining rights. Cannot be challenged by a rival union except during the 60-day freedom period immediately before the 5-year term expires.
Economic and other provisions	Renegotiated not later than 3 years after execution	Wages, benefits and other negotiable terms. Either party may serve notice to renegotiate these provisions once the 3-year mark is reached, even though the union’s representation status is not yet up for challenge.

The 60-day freedom period is the only window in which a rival union may file a valid petition for certification election to challenge the incumbent union’s representation status. Outside that window, a certification petition generally does not raise a legitimate representation question, and an employer that uses such a petition as an excuse to suspend ongoing negotiations — as in the Colegio de San Juan de Letran case discussed below — commits an unfair labor practice.

When a CBA’s term expires before a new agreement is signed, the generally accepted “hold-over” principle keeps the expired agreement’s terms in force on a status-quo basis until a new CBA is concluded, so that employees are not left without contractual protection during a renegotiation period. This does not mean the parties may indefinitely avoid renegotiating; it means neither side may unilaterally withdraw benefits simply because the printed expiration date has passed.

CBA vs Other Workplace Arrangements

Arrangement	Who It Covers	How Terms Are Set	Legally Enforceable?
Collective Bargaining Agreement	Everyone in the certified bargaining unit	Negotiated between employer and the SEBA under Labor Code procedure	Yes — a binding contract with its own enforcement and grievance machinery
Individual employment contract	One employee	Negotiated (or simply offered) between employer and that employee	Yes, but cannot validly reduce statutory minimums or CBA-covered benefits
Company policy / employee handbook	All or specified employees, unilaterally	Set by the employer under management prerogative	Enforceable as company policy, but cannot substitute for a CBA where one exists, and cannot unilaterally reduce benefits already granted — see diminution of benefits
Labor-Management Council / grievance machinery	Employees generally, or the bargaining unit specifically	Created by law or by the CBA itself	A forum for resolving disputes and improving cooperation — it does not replace the CBA itself

Where a company has no bargaining unit at all, the terms and conditions of employment default to what management sets under its management prerogative, bounded by the Labor Code’s minimum labor standards and by any benefit an employer has already granted long enough to become a demandable, non-reducible practice.

Supreme Court Cases Applying These Rules

1. Kiok Loy v. NLRC

G.R. No. L-54334, January 22, 1986. After a union was certified as the exclusive bargaining agent, it submitted a draft CBA and repeatedly asked the employer for a counter-proposal. The employer never replied substantively, requested repeated postponements during compulsory arbitration, and failed to send representatives to hearings. The Supreme Court upheld a finding of unfair labor practice, holding that the law does not tolerate a party “feigning negotiations by going through empty gestures,” and affirmed imposing the union’s draft CBA on the employer.^[4]

Practical lesson: Silence and delay are not a safe alternative to formally responding to a bargaining proposal. Ignoring a union’s proposal can be treated exactly the same as expressly refusing to bargain.

2. Colegio de San Juan de Letran v. Association of Employees and Faculty of Letran

G.R. No. 141471, September 18, 2000. A school delayed responding to its union’s CBA proposal, then changed the union president’s work schedule and later dismissed her for refusing the change, and finally suspended negotiations entirely after a rival union filed a certification petition. The Supreme Court found unfair labor practice on two fronts: the certification petition had been filed outside the valid 60-day freedom period and gave no legitimate basis to halt bargaining, and the union president’s dismissal during active negotiations violated the employees’ right to self-organization.^[5]

Practical lesson: An employer cannot use a procedurally defective rival petition as an excuse to stop bargaining, and disciplinary action against a union officer that lines up suspiciously with the negotiation timeline invites an unfair labor practice finding on top of any dismissal claim — see also Security of Tenure in the Philippines.

3. General Milling Corporation v. Court of Appeals

G.R. No. 146728, February 11, 2004. When its union proposed new CBA terms within the Article 253-A three-year renegotiation window, the employer refused to negotiate at all, asserting the union no longer legally existed. The Supreme Court held this was unfair labor practice: refusing to submit any counter-proposal within the mandatory renegotiation period breaches the duty to bargain, regardless of a disputed claim about the union’s continued existence, and affirmed imposing the union’s draft CBA on the company.^[6]

Practical lesson: A genuine dispute about a union’s status must be raised and resolved through the proper legal channel — it is not a license to simply stop bargaining once the renegotiation period has been triggered.

Consequences of Failing to Bargain in Good Faith

A finding that an employer or a union committed an unfair labor practice by refusing to bargain in good faith can result in: a formal declaration of unfair labor practice against the offending party; imposition of the other party’s draft CBA as the governing agreement, as in Kiok Loy and General Milling Corporation; an order to bargain in good faith going forward, potentially under continuing NLRC supervision; liability for backwages, reinstatement, or damages where the unfair labor practice included illegal dismissal of a union officer, as in Letran; and the reputational and operational cost of a prolonged dispute, including the risk of a lawful strike once conciliation fails.

Unfair labor practice cases fall within the original jurisdiction of the Labor Arbiter, with NLRC and Court of Appeals review, so a party facing this kind of dispute follows largely the same enforcement pipeline as other labor complaints — see DOLE or NLRC: Where Should You File Your Labor Complaint?

What to Do Next

If you are a union officer or employee

Confirm your union’s SEBA status and keep records of the certification election or voluntary recognition.
Serve a clear, written bargaining proposal and keep proof of receipt, so the 10-day reply period is easy to establish later.
Document every negotiation session — who attended, what was discussed, and any postponement requested by the employer.
Escalate promptly through the NCMB if the employer misses deadlines or fails to engage substantively.
File an unfair labor practice complaint with the NLRC if the pattern of conduct suggests bad-faith or surface bargaining.
Watch the calendar on both the three-year renegotiation mark and the 60-day freedom period.

If you are an employer

Respond in writing to any bargaining proposal within ten calendar days, even if the substantive answer is still being prepared.
Send an authorized representative with real decision-making authority to every scheduled session.
Raise any genuine dispute about a union’s legitimacy or a rival petition’s validity through the proper DOLE process — never as a reason to unilaterally stop bargaining.
Avoid disciplinary action against union officers that could be perceived as retaliation timed to active negotiations.
Register every executed CBA with DOLE within 30 days, with complete posting and ratification proof.
Calendar the three-year renegotiation deadline and the 60-day freedom period well ahead of time.

Employer Compliance Checklist

Confirm the union’s current SEBA status before negotiations begin.
Acknowledge and substantively reply to any written bargaining proposal within 10 calendar days.
Keep a written record of every negotiation session, including attendance and topics discussed.
Avoid postponing sessions without a legitimate business reason, and avoid repeated postponements.
Never suspend negotiations based on a certification petition unless it is properly filed within the valid freedom period.
Review disciplinary actions against union officers for negotiation-timing red flags before proceeding.
Ratify and register every CBA with DOLE within 30 days of execution, with complete supporting documents.
Track the three-year economic renegotiation deadline and the five-year representation expiry separately.

Frequently Asked Questions

Is an employer legally required to sign a CBA once a union is certified?

No. The employer is required to bargain in good faith, not to agree to every union demand or to sign any particular draft. However, an employer that refuses to engage in genuine negotiation at all — rather than negotiating and reaching an impasse on the merits — risks an unfair labor practice finding.

Do non-union employees in the same job classification get CBA benefits?

Generally, CBA benefits extend to everyone within the certified bargaining unit, including non-members of the union, since the union bargains on behalf of the whole unit. Whether non-members must pay an agency fee for that benefit depends on the CBA’s own union-security provisions and applicable law.

What happens if the CBA expires before a new one is negotiated?

Under the generally accepted hold-over principle, the expired CBA’s terms typically continue on a status-quo basis until a new agreement is reached, so employees do not automatically lose existing benefits simply because the stated term has ended.

Can a rival union challenge the incumbent union at any time?

No. A rival union may generally only file a valid petition for certification election during the 60-day freedom period immediately preceding the expiration of the incumbent union’s five-year representation term. A petition filed outside that window does not raise a legitimate representation question.

Can an employer refuse to negotiate if it disputes the union’s continued legal existence?

Only through the proper legal channel. As General Milling Corporation v. Court of Appeals shows, unilaterally refusing to bargain because the employer believes the union no longer exists, without resolving that question through the correct DOLE process, has been held to be unfair labor practice.

What can a union do if the employer keeps postponing negotiations?

Document every postponement and missed deadline, escalate through the National Conciliation and Mediation Board, and if the pattern shows bad faith, file an unfair labor practice complaint with the NLRC. Courts have imposed the union’s entire draft CBA on an employer found to have engaged in this kind of stalling.

Conclusion

Collective bargaining in the Philippines is not a courtesy either side extends to the other — it is a legal duty with concrete deadlines, documentation requirements, and consequences for abuse. A union that wins certification gains real leverage, but only if it follows the correct procedure and can document the employer’s conduct. An employer that wants to avoid unfair labor practice exposure needs to treat every bargaining proposal, postponement request, and disciplinary action against a union officer as something that will be scrutinized for good faith later.

The recurring theme across Kiok Loy, Colegio de San Juan de Letran, and General Milling Corporation is that Philippine courts look past the appearance of negotiation to the substance of it: whether a party actually engaged, replied, and tried to reach an agreement, or simply went through the motions while running out the clock. Both unions and employers who keep clear, contemporaneous records of the bargaining process put themselves in the strongest position if a dispute eventually reaches the NLRC.
