2. The article

Since 1947 federal law has let each state ban contracts that require union membership or fees; 26 states now do, the evidence on wages and union strength is contested, and the Supreme Court's 2018 Janus decision extended a related rule to public workers nationwide.

In brief

In 1947 Congress added Section 14(b) to the federal labor law, allowing each state to ban union-security agreements, meaning contracts that require members or fees as a job condition. Arkansas and Florida adopted such laws in November 1944, and 26 states now have them according to the National Conference of State Legislatures as of December 2023. Michigan adopted one in 2012 and repealed it in 2023, with the repeal taking effect in early 2024. Researchers disagree about the effects. The Economic Policy Institute finds wages about 3 percent lower in right-to-work states after controls, while a 2024 Mackinac Center brief finds about 2 percent higher with state fixed effects, and one labor scholar told the Associated Press, "We don't know causation." In 2018 the Supreme Court ruled 5 to 4 in Janus v. AFSCME that public-sector agency fees violate the First Amendment. What the record shows is a rule that voters in each state could change, and an evidence base that has not settled what the rule does.

The record

The federal rule

Section 14(b) of the National Labor Relations Act, codified at 29 U.S.C. 164(b), says nothing in the subchapter "shall be construed as authorizing the execution or application of agreements requiring membership in a labor organization as a condition of employment in any State or Territory in which such execution or application is prohibited by State or Territorial law." The section was added by the Act of June 23, 1947, ch. 120, title I, sec. 101, 61 Stat. 151. (29 U.S.C. 164, Cornell LII; opened, a copy of the statute. The page did not use the name "Taft-Hartley.")
So Congress left the question of union-security clauses to the states. A "right-to-work" law is a state law that bars contracts requiring union membership or payment of fees as a condition of a job.

First state laws, 1944

Arkansas and Florida enacted right-to-work measures in November 1944, "making them the first two states to do so." The Encyclopedia of Arkansas does not rank them. It says the Christian American Association put Arkansas Amendment 34 on the ballot by initiative, that the election had an "unusually high number of irregularities," and that the secretary of state certified it with 105,300 votes for and 87,652 against. It reports that in plantation counties some planters bought poll-tax receipts in large batches and cast votes for sharecroppers. (Encyclopedia of Arkansas, Right to Work Law; opened. A state encyclopedia, secondary.)
Which of the two was "first" is not settled by sources I opened. I did not open Florida's 1944 constitutional text or an official Florida record.

Origins: contested interpretation

Michael Pierce (University of Arkansas), writing for an American Constitution Society symposium on Janus in February 2018, argues that Vance Muse and the Christian American Association promoted right-to-work in the Jim Crow South, tied unions to a threat to the racial order, and that the name came from a 1941 Dallas Morning News editorial by William Ruggles. He cites Stetson Kennedy, George Green, period newsletters and other sources. (ACS Expert Forum; opened. The page is advocacy-oriented, and it is one scholar's argument.)
I did not open a source written by a right-to-work supporter that answers this origin claim. The supporters' present-day case, as summarized in Michigan's House Fiscal Agency bill analysis, is that such laws "encourage economic growth and job creation, and let employees opt out of supporting unions that don't reflect their interests." (Michigan House Fiscal Agency analysis of SB 34, 2023; opened)
Where a law came from does not by itself show what it does today. We report both and score neither.

Count of states

Source	Count	Notes
NCSL page "updated December 19, 2023," table	26 states	Alabama, Arizona, Arkansas, Florida, Georgia, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Mississippi, Nebraska, Nevada, North Carolina, North Dakota, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, West Virginia, Wisconsin, Wyoming
Same NCSL page, metadata description	"28 states and Guam"	Conflicts with the page's own table; likely stale

(NCSL, Right-to-Work Resources; opened.) The same page says Kentucky's HB 1 on January 9, 2017 made it the 27th state and that Michigan's repeal in 2023 is the first in decades, which squares with 26. I did not confirm any change after December 2023, so the count for October 2026 is not independently checked.

Michigan, 2012 and 2023

Michigan became a right-to-work state in 2012 (NCSL). The private-sector law was 2012 PA 348, and the House analysis describes 2012 PA 349 as the public-sector law. (Michigan House Fiscal Agency)
Senate Bill 34 became Public Act 8 of 2023. NCSL gives March 24, 2023 as the date Governor Gretchen Whitmer signed it. The bill did not get enough votes for immediate effect; a December 1, 2023 Small Business Association of Michigan post said it would "likely" take effect February 13, 2024. The Mackinac Center's 2024 brief says it was repealed in February 2024. (SBAM; Mackinac Center, Oct. 24, 2024; both opened.) I did not open the enrolled act or the Michigan Compiled Laws, so the exact effective date rests on secondary sources.
The House analysis summarizes the arguments: repeal supporters cite the "free-rider problem" and lost union funding; opponents of repeal cite economic growth and employee choice. (House Fiscal Agency analysis)
I found no post-repeal data on Michigan wages, union membership or employment in the sources I opened.

Janus v. AFSCME (related, public sector)

Decided June 27, 2018, 5 to 4. Justice Alito wrote for the majority (with Roberts, Kennedy, Thomas, Gorsuch). It held that public-sector agency fees from nonmembers violate the First Amendment and overruled Abood v. Detroit Board of Education, 431 U.S. 209 (1977). Quote: "employees must choose to support the union before anything is taken from them." Justice Kagan dissented (joined by Ginsburg, Breyer, Sotomayor). The page notes 28 states already generally prohibited agency fees. (Janus v. AFSCME, Cornell LII; opened, first 100,000 characters.)
Janus is a constitutional ruling about government employers. Right-to-work statutes are state laws that cover private employers too. They are different rules with similar effects on fees.

Studies on wages, jobs and unions: named, both sides

Study or claim	Finding	Source type
Elise Gould and Will Kimball, Economic Policy Institute (EPI), critique of a Heritage Foundation report	Wages in right-to-work states about 3.1 percent lower after controls ($1,558 a year for a typical full-time worker); unadjusted gap 15.8 percent ($20.66 vs $23.93). EPI calls it an association, a "residual correlation"	EPI blog; opened. EPI is labor-supported
Elise Gould and Heidi Shierholz, EPI, 2011 (as reported by AP in 2012)	About $1,500 less a year, 3.2 percent lower wages, cost-of-living adjusted	AP, Jan. 27, 2012; opened (secondary)
Christopher Douglas, Mackinac Center, Oct. 24, 2024	Using 2010 to 2012 Current Population Survey data, wages about 1.9 percent higher in right-to-work states with state fixed effects	Mackinac brief; opened. Mackinac is a free-market think tank
Indiana Chamber of Commerce study (via AP)	Employment grew 100 percent in right-to-work states from 1977 to 2008 vs 57 percent elsewhere; personal income up 164.4 percent vs 92.8 percent	AP; secondary, business group
Ozkan Eren and Serkan Ozbeklik (via AP)	For Oklahoma and Idaho, right-to-work likely had no impact on manufacturing employment	AP only; I did not open the paper
Gary Chaison, Clark University (via AP)	Debate is polarized: "We don't know causation."	AP
Barry Hirsch and David Macpherson union data (via AP)	In Oklahoma in 2010, 4.7 percent of private-sector workers were covered by contracts but 3.5 percent were dues-paying members	AP; I did not open UnionStats.com

What this case shows

Congress handed a national question to the states, so the fight is state by state. Section 14(b) means a voter's state decides whether a union contract can require fees. Michigan shows the rule can be passed, in 2012, and undone, in 2023.
Who was included in the vote is part of the record. The Encyclopedia of Arkansas describes poll-tax receipts bought in bulk and delayed county returns in the 1944 vote. Pierce argues the early campaigns were tied to preserving racial hierarchy. We report this as one account of how the first laws passed, not as proof about any modern law.
The money evidence is split by method. EPI finds about 3 percent lower wages after controls; Mackinac finds about 2 percent higher with state fixed effects. Chaison says causation is unknown. A reader can see the same question answered two ways.
Janus shows a related rule decided by nine judges, not by a vote. The public-sector fee rule changed nationwide in 2018 with no statute and no ballot. Voters could not amend it by state vote.
Both sides name a person or group who pays. Supporters stress workers who object to paying; opponents stress free riders and weaker union funding. The House analysis records both.

The strongest objections, and our answers

Objection: the racist-origins story is used to smear a policy with broad current support. Mitigation: we attribute it to Pierce, note the source is advocacy-oriented, say we found no rebuttal source, and state that origin does not determine effect.
Objection: wages differ because of industry and cost of living, not the law. That is the core dispute between EPI and Mackinac. Mitigation: both findings are shown with their controls, and neither is picked.
Objection: the Michigan repeal shows voters or legislators chose union fees back. Mitigation: SB 34 was passed by the legislature; nothing in the sources shows a statewide ballot vote.
Objection: Janus and right-to-work are conflated. Mitigation: we state they are different legal rules.
Objection: the count is wrong. Mitigation: we show 26 from NCSL's table, the page's own conflicting "28" description, and that the date is December 2023.

Open questions: what would change our minds

Florida's 1944 text, and which state acted first, were not opened.
The original studies (Gould and Shierholz 2011; Eren and Ozbeklik; Hirsch) were not opened; AP is the source for several.
No post-2024 Michigan data on union membership, wages or jobs were opened.
The state count after December 2023 was not checked against a newer source.
Michigan's effective date (February 13, 2024) rests on a law firm and trade-group post and the Mackinac brief; the act's text was not opened.
Pierce's claims about Muse and the Christian American Association need a second historian and the original documents; none opened.
A supporter-side source on the origin question was not found.
Whether Janus changed union membership: not examined.
