Do Public-Sector Unions Bankrupt Local Governments and Shield Failing Bureaucracies? What Act 10, Municipal Finance Audits, and Post-Janus Data Actually Prove

In August 1937, at the height of the New Deal's expansion of private-sector industrial unionism, President Franklin D. Roosevelt sent a letter to Luther Steward, president of the National Federation of Federal Employees, drawing an uncompromising line between private industry and the civil service. While championing the 1935 National Labor Relations Act (the Wagner Act) for factory and mine workers, Roosevelt insisted that "all Government employees should realize that the process of collective bargaining, as usually understood, cannot be transplanted into the public service," warning that an employer-employee contract binding the sovereign choices of elected lawmakers was incompatible with democratic governance ^{[2], [9]}.

Nearly nine decades later, Roosevelt's warning has become the foundational touchstone of the modern conservative movement's campaign to curtail public-sector unions. Today, the American labor movement is effectively a public-sector phenomenon. According to the U.S. Bureau of Labor Statistics (BLS), while private-sector union membership has eroded from over 30% in the mid-20th century to just 5.9% in 2025, the unionization rate among government employees stands at 32.9%—more than five and a half times higher than in the private economy ^[1]. In local government—encompassing public school teachers, police officers, and firefighters—union membership reaches 39.0%, with over 43% of employees covered by collective bargaining agreements ^[1].

In 2025 and 2026, the ideological clash over government unions has escalated across both federal agencies and state courts. In Washington, President Donald Trump invoked statutory national security exemptions under the Civil Service Reform Act of 1978 (via Executive Orders 14251 and 14343) to strip collective bargaining rights and paid union "official time" from hundreds of thousands of federal employees across the Departments of Defense, Veterans Affairs, Justice, and Homeland Security ^[9]. Simultaneously, in Madison, Wisconsin, a 15-year war over former Republican Governor Scott Walker's landmark 2011 Act 10—which eliminated collective bargaining over benefits and salary schedules for most public employees—reached the doorstep of the Wisconsin Supreme Court in August 2026 after the state's District II Court of Appeals reversed a lower court ruling in July 2026 and upheld the law's constitutionality ^{[3], [10]}.

"In the private sector, unions are constrained by market competition; if they demand too much, the company goes bankrupt and workers lose their jobs. In government, there is no market check—taxpayers are a captive monopoly, and public-sector unions spend hundreds of millions of dollars electing the very politicians who sit across the table from them to negotiate their pay, pensions, and work rules." — Fiscal Conservative Critique of Public-Sector Bargaining, Manhattan Institute & Hoover Institution ^{[2], [9]}

To evaluate whether public-sector unions actually inflate the cost of government, cause state pension crises, and depress public service quality, The Dispatch examined decades of empirical evidence from the Bureau of Labor Statistics (BLS), the National Bureau of Economic Research (NBER), the Center for Retirement Research at Boston College, the Equable Institute, and peer-reviewed quasi-experimental studies of Wisconsin's Act 10 and state duty-to-bargain laws ^{[1], [2], [3], [4], [6], [7]}.

What the Data Shows: The "Two-Bites-at-the-Apple" Dynamic and Municipal Fringe Benefits

The theoretical core of the conservative case against government unions rests on what political scientists call the "inside-outside" or "two-bites-at-the-apple" problem ^[2]. When a private union negotiates with General Motors or Amazon, corporate managers have a fiduciary duty and financial incentive to resist excessive labor costs. In local and state government, however, elected mayors, city council members, and school boards spend taxpayer funds rather than their own capital, and rely heavily on organized public employees for campaign contributions, endorsements, and voter mobilization—particularly in low-turnout, off-cycle municipal and school board elections where turnout routinely falls below 15% ^[2].

How does this political dynamic manifest in municipal balance sheets? For decades, early cross-sectional studies struggled to separate the causal effect of public-sector unions from the fact that liberal, high-cost cities were simply more likely to unionize in the first place ^[2]. In a landmark 2015 study published in The Journal of Politics ("Public Sector Unions and the Costs of Government"), UC Berkeley political scientist Sarah F. Anzia and Stanford University's Terry M. Moe overcame this hurdle by analyzing panel datasets tracking hundreds of U.S. municipalities from 1972 to 1987 (as cities first adopted collective bargaining) and from 1992 to 2010, incorporating city and year fixed effects ^[2].

Their findings revealed a critical distinction between visible base salaries and opaque fringe benefits ^[2]:

• Modest Impact on Base Wages and Staffing: In cities where police officers recently gained collective bargaining rights, average base wages rose by roughly 2.3% and staffing per capita rose by a similar margin, producing an initial 3.7% increase in per-capita police payroll expenditures. In cities with long-standing collective bargaining (1992–2010), per-capita spending on salaries was 4.3% higher for police and roughly 9% higher for firefighters compared to non-bargaining municipalities ^[2].
• Massive Surge in Health and Fringe Benefits: When Anzia and Moe examined non-wage compensation, the union effect multiplied dramatically. Cities with collective bargaining spent 16.5% more per capita on health and fringe benefits for police officers and roughly 25% more per capita on fringe benefits for firefighters than cities without collective bargaining ^[2].
• Why Politicians Prefer Hidden Benefits: As Anzia and Moe documented, voters and local journalists easily understand and scrutinize a 10% across-the-board pay raise or an immediate property tax hike. By contrast, reducing health insurance co-pays, guaranteeing zero-deductible retiree medical coverage (Other Post-Employment Benefits, or OPEB), or sweetening pension multipliers shifts the fiscal burden off current operating budgets and onto future taxpayers—allowing local politicians to satisfy union allies without triggering immediate voter backlash ^{[2], [8]}.

The Wisconsin Act 10 Natural Experiment: Seniority Pay vs. Classroom Merit

Nowhere has the conservative thesis on public-sector unions been tested more rigorously than in public K–12 education. Conservative education reformers have long argued that teachers' union collective bargaining agreements (CBAs) misallocate billions of taxpayer dollars by enforcing rigid "step-and-lane" salary schedules—which dictate a teacher's pay strictly by years of tenure ("steps") and graduate course credits ("lanes")—while prohibiting merit pay for classroom effectiveness or differential bonuses for hard-to-staff subjects like math, physics, and special education ^[3].

For decades, dozens of empirical studies in the economics of education have shown that after a teacher's first three to five years in the classroom, additional years of seniority and possession of a master's degree have virtually zero correlation with student test-score gains (known as teacher "Value-Added," or VA) ^[3]. Yet prior to 2011, union contracts forced nearly 100% of unionized school districts to pay a 20-year veteran teacher in the bottom 10th percentile of instructional effectiveness up to twice as much as a 3-year teacher in the top 95th percentile ^[3].

In June 2011, Wisconsin enacted Act 10 (the Budget Repair Bill), providing economists with one of the cleanest natural experiments in modern labor history ^{[3], [5]}. Act 10 stripped public school teachers' unions of the authority to bargain over salary schedules, healthcare, pensions, and work rules (restricting bargaining solely to base wage increases capped at the rate of inflation), required employees to contribute 5.8% of their salary toward pensions and at least 12.6% toward health insurance premiums, banned automatic payroll dues deduction, and required unions to win annual recertification elections from a majority of all eligible workers ^{[3], [10]}.

In a landmark 2021 study published in the American Economic Journal: Economic Policy ("The Labor Market for Teachers under Different Pay Schemes"), Yale School of Management and NBER economist Barbara Biasi exploited the staggered expiration dates of pre-existing union contracts across Wisconsin's 428 school districts to measure what happened when districts were freed from union salary schedules ^[3]:

1. The Split Between Flexible-Pay and Seniority-Pay Districts: Roughly half of Wisconsin's school districts used their new autonomy under Act 10 to abandon lock-step union schedules and adopt Flexible Pay (FP)—rewarding high-performing teachers, paying bonuses for high-need roles, and negotiating individual salaries—while the other half voluntarily retained traditional Seniority Pay (SP) schedules ^[3].
2. Pay Linked to Classroom Value-Added: In districts that adopted flexible pay, salaries for top-quartile teachers (measured by objective student learning gains) rose significantly relative to low-value-added teachers with identical seniority and credentials ^[3].
3. Positive Sorting of High-Quality Educators: Flexible-pay districts successfully attracted high-value-added teachers away from neighboring districts that clung to union-style seniority pay, while low-performing teachers exited flexible-pay districts or left the profession at higher rates ^[3].
4. Higher Effort and Student Achievement: Combining the influx of higher-caliber teachers with increased classroom effort from incumbent teachers responding to performance incentives, workforce quality and student standardized test scores rose measurably in flexible-pay districts relative to seniority-pay districts—without increasing total per-pupil payroll budgets ^[3].

Complementing Biasi's Wisconsin findings, a sweeping national study published in the American Economic Journal: Economic Policy in 2019 by Cornell University economist Michael F. Lovenheim and Alexander Willén ("The Long-Run Effects of Teacher Collective Bargaining") examined the long-term adult labor market outcomes of students who attended public schools across the 33 states that enacted mandatory teacher "duty-to-bargain" laws between 1960 and 1987 ^[4].

Linking state collective bargaining timelines to adult earnings data from the American Community Survey (ACS) and the National Longitudinal Survey of Youth (NLSY79), Lovenheim and Willén found that students who spent 10 years in a state with a mandatory teacher collective bargaining law experienced a statistically significant $2,134 (or 3.93%) reduction in annual adult earnings among men, a 0.42-hour reduction in weekly hours worked, lower employment rates, and lower measured non-cognitive skill development—aggregating to roughly $199.6 billion in lost annual earnings across affected cohorts nationwide, with the steepest economic penalties concentrated among Black and Hispanic students ^[4].

The Full Picture: Where the Anti-Union Narrative Collides with Fiscal and Educational Data

While the empirical literature strongly supports conservative criticisms of union-mandated seniority pay and municipal fringe-benefit inflation, a balanced, evidence-based analysis reveals three major areas where conservative talking points overreach or misrepresent the data ^{[1], [5], [6]}.

1. The Short-Run Cost of Blanket Benefit Cuts

First, conservative lawmakers often conflate reforming rigid union pay rules with imposing across-the-board compensation cuts. While Barbara Biasi's research showed that replacing seniority schedules with flexible merit pay improved teacher quality ^[3], a separate peer-reviewed study of Wisconsin's Act 10 by economist E. Jason Baron (published in the Economics of Education Review, 2018) measured the immediate shock of Act 10 as a whole—including its mandatory 8% to 10% cut in net take-home pay from higher pension and health insurance contributions ^[5].

Baron found that in the first two to three years after pre-existing contracts expired, Act 10 triggered an immediate surge in teacher turnover and early retirements (rising by 3 to 5 percentage points above baseline), which replaced experienced educators with novice first-year teachers and caused a short-run decline of roughly 0.15 to 0.20 standard deviations in average district standardized test scores—concentrated primarily among lower-performing students in districts that merely cut take-home pay without implementing targeted retention bonuses ^[5]. In short, the data shows that while deregulating rigid salary schedules improves public schools, blunt across-the-board pay cuts degrade workforce stability ^{[3], [5]}.

2. The $1.35 Trillion Pension Myth: Unions vs. Legislative Fiscal Recklessness

Second, conservative commentators routinely assert that public-sector unions are the primary cause of the nation's $1.27 trillion to $1.35 trillion in unfunded state and local pension liabilities (which stood at an average national funded ratio of 81.4% to 82.5% in 2025 according to the Equable Institute, or vastly larger when valued using risk-free discount rates as demonstrated by Stanford/NBER economists Robert Novy-Marx and Joshua Rauh) ^{[7], [8]}.

When economists at the Center for Retirement Research (CRR) at Boston College (led by Alicia H. Munnell) tested the link between public-sector unionization and pension underfunding across every major state and local retirement system in the United States, they uncovered a striking empirical reality: union strength has no statistically significant direct effect on pension plan benefit generosity, and only a weak, indirect correlation with unfunded pension liabilities ^[6].

Why does the union-pension narrative break down across the 50 states? The data points to three structural reasons ^{[6], [7]}:

• Pensions Are Set by State Statute, Not Local Bargaining: Unlike base salaries or municipal health insurance co-pays, public pension benefit formulas in the vast majority of states are established by state legislatures through statutory law rather than negotiated at local collective bargaining tables ^[6].
• Deep Pension Crises in Non-Union Southern States: If public-sector collective bargaining were the primary cause of pension insolvency, states that prohibit or severely restrict public-sector collective bargaining would enjoy pristine pension balance sheets. In reality, several staunchly anti-union or non-bargaining states—including Kentucky (~54.4% funded), Mississippi (~56.2% funded), and South Carolina (~59.1% funded)—rank alongside heavily unionized Illinois (~52.1% funded) and New Jersey (~53.8% funded) at the very bottom of national pension solvency rankings ^[7]. Conversely, two of the most heavily unionized public-sector states in America—New York (~95.1% funded) and Washington (~94.6% funded)—maintain some of the healthiest, best-funded pension systems in the country ^{[6], [7]}.
• The Real Culprit: Legislative "Contribution Holidays" and Return Assumptions: Actuarial decompositions by Boston College CRR and The Pew Charitable Trusts prove that over two-thirds of modern pension debt accumulated since 2001 stems from two bipartisan fiscal habits: state legislatures systematically failing to pay their full Actuarially Determined Employer Contribution (ADEC) during budget downturns (effectively borrowing from the pension fund to pay for tax cuts or current spending), and pension boards assuming unrealistic 7.5% to 8.0% annual investment returns rather than discounting guaranteed liabilities at municipal bond or Treasury rates (as documented by Novy-Marx and Rauh) ^{[6], [8]}.

3. The Post-Janus Resilience and the Police/Fire Exemption Paradox

Finally, recent labor data challenges both conservative predictions about voluntary union membership and the internal consistency of Republican labor reforms ^{[1], [10]}. When the U.S. Supreme Court issued its landmark 5–4 ruling in Janus v. AFSCME Council 31 (2018)—holding that forcing non-member public employees to pay mandatory "agency shop" fees violates the First Amendment—conservative legal analysts predicted that public-sector unions would lose 20% to 30% of their membership and billions in revenue ^[1].

Eight years later, Bureau of Labor Statistics data shows that while the pool of non-member "agency fee payers" represented by unions dropped sharply after 2018 (narrowing the gap between union members and represented non-members to just 3.2 percentage points by 2025), actual dues-paying public-sector union membership barely moved—holding steady at 32.2% in 2024 and 32.9% in 2025 (7.2 million members) compared to 34.4% in 2017 ^[1]. Only where states paired Janus with aggressive administrative hurdles—such as Wisconsin's Act 10 or Florida's 2023 Senate Bill 256, which banned payroll dues deduction and forced unions to recertify if active dues-paying membership fell below 60%—did local bargaining units decertify in large numbers ^[10].

Moreover, the constitutional litigation over Wisconsin's Act 10 in 2024–2026 (Abbotsford Education Association v. Wisconsin Employment Relations Commission) has spotlighted a glaring political paradox in conservative labor laws ^[10]. Both Wisconsin's Act 10 in 2011 and Florida's SB 256 in 2023 stripped collective bargaining or dues-deduction rights from teachers, clerical staff, and municipal sanitation workers, yet explicitly exempted police, correctional, and firefighter unions—groups that frequently endorse Republican candidates ^{[2], [10]}. As Anzia and Moe's municipal finance data demonstrates, police and firefighter unions are the exact bargaining units that exert the steepest upward pressure on municipal overtime, health benefits (+16.5% to +25%), early-retirement disability pensions, and binding disciplinary arbitration ^[2].

Conclusion: Separating Structural Reform from Partisan Carve-Outs

When evaluated through rigorous economic and fiscal evidence, the debate over public-sector unions defies simplistic partisan slogans ^{[2], [3], [6]}. Conservatives are fundamentally right that government collective bargaining operates under vastly different economic incentives than private-sector unionism ^[2]. Empirical data confirms that municipal collective bargaining drives up per-capita taxpayer costs primarily by expanding opaque health and fringe benefits (+16.5% to +25%) ^[2]; that union-mandated "step-and-lane" seniority schedules suppress teacher quality compared to flexible performance-based pay ^[3]; and that mandatory teacher duty-to-bargain laws have historically imposed measurable long-run earnings penalties on male and minority students ^[4].

At the same time, blaming public-sector unions for the entirety of state and local fiscal distress—particularly the $1.35 trillion unfunded pension overhang—allows state lawmakers of both parties to evade responsibility for their own budgetary malpractice ^{[6], [7], [8]}. As pension audits from Boston College and the Equable Institute prove, heavily unionized states that consistently pay their actuarially required contributions (such as New York and Washington) enjoy near-100% pension funding, while non-bargaining states whose legislatures habitually underfunded their systems (such as Mississippi, South Carolina, and Kentucky) face severe retirement shortfalls ^{[6], [7]}.

Ultimately, the evidence points toward principled, non-discriminatory institutional reform rather than selective political retribution: replacing rigid seniority-only pay grids with performance-linked compensation that rewards effective educators without slashing overall school budgets ^{[3], [5]}; enforcing strict statutory requirements that state legislatures pay 100% of their actuarially determined pension contributions under realistic discount rates ^{[6], [8]}; moving local elections onto high-turnout general election ballots to dilute special-interest capture; and applying collective bargaining and disciplinary transparency rules evenly across all public employees—without carving out partisan exemptions for favored unions ^{[2], [10]}.
