Understanding Project Labor Agreements: What They Are and Why They Matter

A Project Labor Agreement (PLA) is a contract used for large construction projects. It is negotiated between a project owner, such as a government agency, and labor unions before the work begins. The agreement sets rules for wages, working hours, safety standards, dispute resolution, and other working conditions. By establishing these terms upfront, PLAs are meant to keep projects running smoothly, without costly delays or labor disputes.

PLAs are most common on large or complex projects, where stability and efficiency are critical. These can include highways, schools, bridges, airports, and government buildings. Public agencies, such as state or city governments, often use PLAs, but private companies can also use them. For example, Sound Transit in the Seattle area has used PLAs for its rail and transit projects.

Why PLAs Involve Labor Unions
PLAs generally involve labor unions, which represent workers in collective bargaining. They provide a ready supply of trained and skilled workers through union hiring. This system helps project owners avoid worker shortages and ensures that safety and training standards are satisfied. In return, unions agree not to strike or slow down work for the duration of the project.

Nonunion contractors are not excluded from bidding on projects with PLAs, but they must follow union work rules and often contribute to union benefit funds while working under the agreement. This ensures consistency across the workforce, although it is one reason PLAs are controversial in areas where non-union contractors are more common, such as much of Eastern Washington.

Why PLAs Are Used
Supporters argue that PLAs provide “labor peace.” This means that there are no strikes or disputes during construction, which helps projects stay on schedule and within budget. They also ensure that workers are paid fair wages and receive benefits. Because PLAs standardize rules across all contractors, they can improve safety, training, and quality of work.
​
Critics argue that PLAs can raise costs because union wages and benefits are often higher. They also argue that PLAs may discourage small or nonunion contractors from bidding, which can reduce competition. This concern is particularly strong in regions where nonunion firms dominate the construction market.

Are PLAs Anti-Competitive?
At first glance, PLAs may appear to reduce competition. However, they are not legally considered a form of antitrust or anti-competition. Courts, including the U.S. Supreme Court, have ruled that PLAs are labor agreements and not collusion between businesses. In the 1993 Boston Harbor case, the Court upheld the use of PLAs on public projects, confirming that government owners have the right to set contract conditions, just like private owners.
​
Contractors—union and nonunion —are still free to bid on PLA projects. The bidding process remains competitive, even though all contractors must follow the same union-style rules once they are hired. The purpose of a PLA is to guarantee stability and efficiency, not to limit participation. However, the effect of PLAs on local competition remains a topic of heated policy debate.

Ramifications for Public Works
When a PLA is required for a public project, all contractors must follow its terms. This can help taxpayers prevent cost overruns caused by strikes or delays. It also provides uniform wages and safety standards for workers. However, mandatory PLAs may limit participation from small or local contractors who find union requirements burdensome. In Washington, this debate continues as lawmakers and agencies weigh the balance between efficiency and open competition.

Conclusion
Project Labor Agreements are powerful tools that shape the completion of large construction projects. They create stability, guarantee a skilled workforce, and reduce the risk of labor disputes. Simultaneously, they raise questions about cost and competition, especially in areas where nonunion firms are common. Understanding PLAs helps taxpayers, businesses, and policymakers make informed decisions about balancing fairness, quality, and efficiency in public works.
