You get dispatched to a big job, a new hospital, a transit line, a federal building, and someone mentions it is "under a PLA." A project labor agreement (PLA) is a contract that sets the labor rules for one specific construction project, for every contractor on it. If you work in the trades, PLAs affect who gets hired onto a job, how disputes get settled, and whether the job can be shut down by a strike. This guide explains what a PLA is, how it differs from the agreement your local already has, where federal PLA policy stands as of fall 2026, and what to ask before you start a PLA job.
One note up front: a PLA is not the same thing as prevailing wage. Prevailing wage laws set minimum pay on public work. A PLA is a negotiated agreement covering much more than pay. If you want the wage side, read our separate prevailing wage and Davis-Bacon explainer. This article stays on the agreement itself.
What is a project labor agreement?
The Congressional Research Service, in an August 2026 brief on PLAs, defines a PLA as a prehire collective bargaining agreement with one or more unions. It sets the terms and conditions of employment for a particular construction project and generally requires all contractors and subcontractors on that project to follow the same standards.
Three ideas in that definition matter to you as a worker:
- Prehire. The agreement is signed before the workforce is hired. That is unusual in labor law, and it is allowed for construction specifically.
- Project-specific. It covers one job, from start to finish, not a contractor's entire business.
- Everyone on site. It generally binds every contractor and sub, so the rules on the job are the same whether you work for the general contractor or a small specialty sub.
The legal basis is Section 8(f) of the National Labor Relations Act, which lets construction employers sign prehire agreements. According to CRS, Congress allowed this because construction projects are short-term and it is hard to bargain after a crew is already hired. CRS also notes that PLAs have reportedly been used on publicly funded construction since the 1930s.
PLA vs. your local's collective bargaining agreement
Most union tradespeople already work under their local's agreement with a contractor association. A PLA sits on top of that for one project. Here is how they compare in general terms:
| Question | Your local's agreement | A project labor agreement |
|---|---|---|
| What does it cover? | All work your trade does for signatory contractors in the area | All crafts and contractors on one project |
| Who signs? | Your local and contractors or their association | One or more unions and the contractors on the project |
| How long does it last? | A set term, renegotiated periodically | The life of the project |
| Strikes? | Depends on the agreement and the bargaining cycle | Typically barred for the project's duration (required under the federal order) |
| Disputes? | Your local's grievance procedure | A binding dispute procedure for the project (required under the federal order) |
How a PLA interacts with your craft agreement is set in the PLA itself, and it differs from project to project. The only reliable way to know is to read the PLA for your job or ask your business agent.
Project labor agreements on federal jobs: the $35 million rule
Federal PLA policy has flipped with nearly every administration. CRS lays out the history:
- 1992: Executive Order 12818 barred agencies from requiring PLAs.
- 1993: EO 12836 revoked that ban.
- 1997: A presidential memorandum encouraged PLAs on federal projects over $5 million.
- 2001: EO 13202 revoked the earlier policy and pushed government neutrality.
- 2009: EO 13502 encouraged, but did not require, PLAs on projects of $25 million or more.
- 2022: EO 14063, issued February 4, 2022, made PLAs a requirement on large-scale federal construction.
Under EO 14063, contractors and subcontractors on federal construction projects with a total estimated cost of $35 million or more must agree to negotiate or become party to a PLA. The PLA must guarantee against strikes, lockouts and similar disruptions, and must set binding procedures for resolving labor disputes during the project. A final rule amending the Federal Acquisition Regulation to carry this out was published December 22, 2023.
Agencies can grant exceptions, with a written explanation, when a PLA would not advance economy and efficiency, when a market analysis shows it would substantially reduce competition among bidders, or when it would conflict with other laws or orders.
Where federal PLA policy stands in 2026
This has been a contested area, so here is the state of play as reported in the sources we checked:
- Defense Department pushback. The Economic Policy Institute's policy tracker reports that the Pentagon directed contracting officers to stop using PLAs on large-scale construction. North America's Building Trades Unions (NABTU) sued, and a federal judge issued a preliminary injunction blocking the Defense Department memos. The tracker then reports an OMB memo from Director Russell Vought stating that EO 14063 remains in effect and that blanket deviations barring PLAs are not allowed.
- The order is still in place. The August 2026 CRS brief describes EO 14063 as remaining in place.
- Contractor lawsuit. Associated Builders and Contractors and its Florida chapter challenged the order. A district court denied a preliminary injunction in March 2024, and in April 2026 a three-judge Eleventh Circuit panel affirmed, finding the plaintiffs unlikely to win on any claim. The plaintiffs asked the full Eleventh Circuit for rehearing in June 2026, so the case was still pending when CRS wrote its brief.
- Bills in Congress. The Fair and Open Competition Act would bar agencies from requiring or prohibiting labor agreements on federal construction. Other bills, such as the All Aboard Act of 2025, would require or favor PLAs for certain programs.
The practical meaning for workers: on big federal jobs, PLAs are still the rule, but the policy is under legal and political pressure. Check the current status before assuming a particular federal project will carry one.
What a PLA means for you on the job
Because terms are negotiated project by project, treat the following as the questions to answer for your job, not guaranteed features:
- How does hiring work? Supporters describe PLAs as a way to set pay standards and favor local or union hiring; EPI frames losing PLAs as losing that leverage. Find out whether referral runs through your local's hiring hall and whether there are local hire or apprentice targets.
- What happens in a dispute? Federal PLAs must include binding dispute procedures. Learn whether a problem goes through your normal grievance process or a project-level committee first.
- Can you strike or be locked out? Under a federal PLA, no, for the life of the project. That protects your paycheck from a lockout and also means your local cannot pull you off that job over a contract fight elsewhere.
- Who else is on site? PLAs generally bind every contractor, which can include firms that are not normally union signatories. You may be working beside crews new to union rules.
- Which rules win if they conflict? Ask whether the PLA or your craft agreement controls on hours, shifts and overtime.
The debate, in plain terms
You will hear strong opinions on PLAs, so it helps to know both sides. Supporters, including EPI, argue that PLAs help projects finish on time, keep labor peace, support worker well-being and connect projects to local communities. Opponents, including ABC in its lawsuit, argue that requiring PLAs pressures nonunion contractors, whose employees have chosen not to unionize, and narrows competition for public contracts. The exceptions in EO 14063 exist partly to address that competition concern.
For a union tradesperson, the most direct effect is simple: PLAs tend to put large public projects under union-standard conditions. If you are comparing paths, our merit shop vs. union guide covers the broader picture.
Before you start a PLA job: a worker's checklist
- Ask your business agent or steward for a copy of the PLA, or at least a summary.
- Confirm how you were referred and whether any local hire or apprentice ratios apply.
- Find out which agreement controls wages, hours and overtime on this project.
- Learn the project's dispute procedure and who your steward is on site.
- Note the no-strike terms so you know what is off the table during the job.
- Keep your own records of hours and pay, as on any job.
Bottom line
Verdict: A project labor agreement is a one-project contract that puts every contractor under the same labor rules, trades the right to strike for labor peace, and usually brings union standards to big public jobs. Federal PLAs are still required on most projects of $35 million or more as of fall 2026, but the policy is under legal and political pressure. On any PLA job, read the agreement or get a summary before day one.
