Michigan Repealed Right-to-Work in 2024. Union Membership Immediately Rebounded.

A rare reversal broke a nearly 60-year pattern

As of 2026, 26 states have right-to-work laws, which prohibit requiring union membership or payment of union dues as a condition of employment. These laws are authorized under Section 14(b) of the National Labor Relations Act, which specifically permits individual states to pass this kind of legislation. The count dropped from 27 after Michigan repealed its right-to-work law effective February 13, 2024 (some sources cite March 30, 2024, depending on which specific provision), becoming the first state to reverse such a law in nearly 60 years, since Indiana did so in 1965.

Public sector workers in Michigan retain a separate, distinct protection regardless of the repeal: federal constitutional law (independent of any state right-to-work statute) already prevents forcing public employees specifically to pay union dues, meaning the practical effect of Michigan's repeal was concentrated in the private sector, where no such federal baseline protection exists.

Michigan's own before-and-after data offers one of the clearest real-world case studies available

During the 11 years Michigan's right-to-work law was in effect (2013-2024), the state lost nearly 70,000 union members, and union density fell by more than 21% over that period, according to Illinois Economic Policy Institute analysis of BLS and Census data. In the first full year after repeal, Michigan gained 15,000 union members, with union density rising from 12.8% to 13.4%, more than a 5% relative increase in a single year.

As of early 2026, Michigan Senate Republicans introduced Senate Bill 436 seeking to restore the state's right-to-work status, though its prospects depend heavily on the composition of the state legislature, meaning this specific reversal itself could potentially be reversed again depending on future election outcomes.

National union membership trends, and the correlation with right-to-work status

• The U.S. lost 170,000 union members nationally in 2024, but according to Illinois Economic Policy Institute analysis, that decline was disproportionately concentrated in states that have adopted right-to-work laws specifically
• The national union membership rate stood at approximately 10% of wage and salary workers in 2025, according to Bureau of Labor Statistics data
• States with the highest union membership rates tend to be non-right-to-work states (Hawaii, New York, Washington, California, Oregon), while states with the lowest rates tend to be right-to-work states (South Carolina, North Carolina, Georgia, Texas, Utah), a real correlation, though establishing the specific causal direction (whether right-to-work laws suppress membership, or pre-existing lower union culture leads states to adopt such laws) is genuinely harder to isolate from this pattern alone
• Illinois-specific research found union members there earned 12% higher wages on average, were 8% more likely to be homeowners, and 5% more likely to have health insurance coverage than non-union workers, though Illinois is not a right-to-work state, so this specific comparison reflects union membership effects generally, not a right-to-work-specific finding

The economic argument runs in genuinely opposite directions depending on the source

Proponents of right-to-work laws argue they attract businesses and give individual workers freedom of choice over union membership and dues, framing mandatory union payment as an unfair imposition on workers who don't wish to join. Critics frame these same laws as effectively "anti-union" by design, arguing they create a "free-rider" problem, since unions remain legally required to represent all employees in a bargaining unit, including those who choose not to pay dues, which structurally weakens union finances and bargaining leverage over time even without banning unions outright.

The core disagreement

Right-to-work supporters generally argue individual workers shouldn't be compelled to financially support an organization they don't wish to join as a condition of keeping their job, framing this as a matter of personal economic freedom, and argue these laws help attract business investment and job creation to a state. Opponents generally argue the laws are specifically designed to weaken union bargaining power and finances through the free-rider dynamic, pointing to Michigan's own before-and-after membership data, and broader research on the Illinois union wage premium, as evidence that weaker unions correlate with worse outcomes for workers generally, not just union members specifically. Both sides broadly agree Michigan's 2024 repeal represents a genuinely significant test case, the first reversal of an existing right-to-work law in nearly six decades, and its ultimate political durability (given the pending Senate Bill 436 to restore it) remains a live, unresolved question.
