Labor organizations were once viewed by some as a criminal conspiracy. Now, the U.S. labor movement has grown to include millions of members. Today, federal laws enforced by the U.S. Department of Labor, along with state laws, recognize the rights of many types of workers to form a union. Unions uphold labor standards. They also protect employee rights within the federal government and across various industries.
Read on for more information about relevant labor laws, what a labor union does, and a list of labor unions in the U.S.
What Is a Labor Union?
A labor union is an organization of workers who use collective bargaining to negotiate with employers for improvements to wages, benefits, and working conditions. These negotiations are then outlined in a union contract or collective bargaining agreement. Members often pay union dues to support union officials. These officials provide union representation. They also advocate for employee rights and interests across various industries and trades. To learn more about labor unions in general, visit FindLaw's article Union Basics.
Relevant Labor Laws
Several labor laws protect the rights of workers to form or join labor unions. The most prominent federal law is the National Labor Relations Act (NLRA). The NLRA grants employees the right to organize and collectively bargain. It also protects workers' right to unionize without interference from employers. The National Labor Relations Board (NLRB) enforces these protections. For more information, read FindLaw's article “What is the NLRB?"
Knowing whether your state is a “right to work" state is also important. In "right to work" states, employees can't be compelled to join or financially support a union. Right to work laws uphold workers' freedom to choose union representation without coercion or discrimination. Read FindLaw's “Right to Work Laws by State" to find out whether your state is a right to work state.
List of Unions in the U.S.
Unions range in size—from less than a hundred union members to millions. Labor unions exist for many different sectors and professions.
