Is Illinois a Right-to-Work State? (2026)

What Right-to-Work Laws Mean

A right-to-work law bans agreements that make paying a union a condition of keeping your job. Those agreements are called union security agreements, and federal labor law permits them under 29 U.S.C. 158(a)(3). A separate federal provision, 29 U.S.C. 164(b), lets individual states outlaw them.

So the choice belongs to each state. States that pass a ban become right-to-work states. States that stay silent, or that protect the agreements outright, do not. The label is also easy to confuse with at-will employment, but right-to-work and at-will answer different questions.

Illinois's Position on Right-to-Work

Illinois is not a right-to-work state. It moved in the opposite direction with the Collective Bargaining Freedom Act, 820 ILCS 12, which declares it the policy of the state that employers, employees, and their labor organizations may freely negotiate union security agreements, including those requiring dues to be paid to a labor organization.

The Act goes further than a simple policy statement. Under Section 15, employers and unions covered by the National Labor Relations Act may execute and apply agreements requiring union membership as a condition of employment anywhere within the entire state, to the full extent federal law allows.

Union Membership and Dues in Illinois

Because state law protects these agreements, a private-sector contract in Illinois may require you to pay dues once you are covered by it. The Collective Bargaining Freedom Act also settles who gets to change that rule:

• Only the General Assembly may enact legislation affecting union security agreements.
• No city, county, or other local government may pass or enforce a right-to-work ordinance.
• Any local rule that restricts these agreements is a violation of the Act and is void.

That last point closed a real fight. Before the Act, individual towns tried to create local right-to-work zones. The statute is written as a denial and limitation of home rule powers under the Illinois Constitution, so those local efforts no longer have a legal footing.

The Act also gives people a way to enforce it. Any interested party harmed by a violation may file suit in circuit court in the county where the violation happened or where a party lives, and one or more people may sue on behalf of others in the same position.

At-Will Employment and Worker Rights in Illinois

Illinois is one of many at-will employment states. Generally speaking, you or your employer may end the job at any time for almost any reason that is not unlawful. A collective bargaining agreement sits on top of that baseline and often adds protections, such as requiring cause before discipline or termination.

Worker organizing rights in Illinois also carry constitutional weight. Section 25 of Article I of the Illinois Constitution gives employees the fundamental right to organize and bargain collectively through representatives of their own choosing over wages, hours, working conditions, and workplace safety. It states that no law shall be passed that interferes with, negates, or diminishes that right, including any law or ordinance prohibiting agreements that require membership in an organization as a condition of employment.

In practice, that means a future right-to-work bill in Illinois would run into the constitution itself, not just a statute. Your specific obligations still depend on the contract covering your job and on the wider rules of Illinois employment law, so reading it is usually the fastest way to know where you stand.
