Are labor unions good for workers and the economy?

Your question touches both history and current economics — I'll pull recent research on how unions affect wages, benefits, and growth.

Labor unions have both significant benefits and significant costs for workers and the economy - research finds the effects cut both ways.

1. Benefits for Workers - Well Documented

Higher wages - The union wage premium:
Economists estimate unions raise the wages of their members by 10 to 15 percent compared to similar non-union workers. Other estimates control for worker characteristics and use regression discontinuity analysis of workplaces that barely voted to unionize and find a causal boost around 10 to 15 percent, with larger effects for longer-tenured workers.

Raw Bureau of Labor Statistics data from 2025 shows median weekly wages of $1,404 for union members compared to $1,174 for nonunion workers, though those figures don't adjust for occupation, industry or region.

The premium is larger for low-wage workers. The Center for Economic and Policy Research finds unionization raises wages about 14% for the typical worker, and almost 21% for a worker at the 10th percentile of the pay scale.

Better benefits and working conditions:
Unions also improve fringe benefits and workplace procedures such as retirement plans, workplace grievance policies, and predictable scheduling. These workplace improvements contribute substantially to middle-class financial stability and worker well-being.

Unionized workers are significantly more likely to have employer-sponsored health coverage and retirement plans. One study estimated the average worker values their ability to avoid short-notice schedule changes at up to 20 percent of their wages.

Other worker benefits include:

U.S. public opinion reflects this: About half (53%) say unions have had a positive effect on the salaries and benefits of union workers, while just 17% say they have had a negative effect.

About 14.7 million Americans belonged to a union in 2025, representing 10% of all wage and salary workers, and only about 10 percent of U.S. wage and salary workers belonged to a union in 2025, yet research finds the economic footprint stretches well beyond members.

2. Benefits for the Wider Economy

The U.S. Treasury Department's 2023 report - its most comprehensive look at the role unions play - concluded unions contribute to a more robust and resilient economy.

Mechanisms cited:

Brookings notes: unions lift wages, reduce inequality, and shape how work is organized.

3. Costs and Criticisms for the Economy and Businesses

Critics and recent meta-analyses point to trade-offs:

Higher business costs and slower growth:
In a 2025 review of 147 studies, researchers at the free-market Mercatus Center concluded that powerful labor unions can lead to slower job growth and fewer jobs for unionized workers, reduce company investments in research and development, and increase the likelihood of company closures.

A related Mercatus analysis found as powerful unions win significant labor market negotiations to increase worker pay, profits fall and businesses cut back on investments, which harms firm and worker productivity.

The "union tax" on consumers:
Economist Barry Hirsch concludes when unions do raise wages, businesses must bear those costs as a union tax. As business expenses grow, industry passes along the cost to consumers directly through price increases, quality reductions, or access limitations, or indirectly by disrupting resource allocation and decreasing product and service availability.

For example, economists note "cost-push inflation," where higher wages lead to higher prices, with one study finding a 1-standard-deviation increase in union membership was associated with an 8.5 percent higher inflation rate at the peak before monetary adjustment.

A specific industry example: former Heritage Foundation economist James Sherk notes the combination of union premium pay and inefficient work rules added about $800 to the cost of every Detroit vehicle in 2006.

Other potential inefficiencies cited in the literature:

Since the 1980s, unions have delivered only modest wage increases, at best, which suggests price increases are limited by declining union membership and power.

One macroeconomic estimate finds a one-percentage-point increase in state-level union membership is associated with about a quarter-point decrease in real GDP growth, though other economists argue GDP growth that flows primarily to top earners produces different outcomes than broadly shared wage gains.

Long-term competitiveness concern:
The economic rise and fall of the Rust Belt serves as a cautionary tale - powerful and adversarial unions causing labor conflicts strangled productivity and investment in Rust Belt manufacturing, leaving workers worse off.

Bottom Line

For workers, especially middle- and low-wage workers: The evidence is strong that union membership improves pay, benefits, job security, and workplace voice, and that spillover effects lift pay even for non-members in the same labor market.

For the economy as a whole: The effect is mixed and depends on what you value. Unions tend to compress inequality, stabilize spending during recessions, and can modestly improve productivity through lower turnover and worker input. At the same time, they raise labor costs, which can slow hiring, reduce investment and R&D, raise consumer prices in less competitive markets, and reduce flexibility.

In short, unions are generally good for workers who are in them (and often for nearby non-union workers), but for the economy overall they represent a trade-off: more equality and stability versus somewhat lower efficiency and growth - a trade-off that looks like a feature if you prioritize broadly shared prosperity, and a bug if you prioritize maximum GDP growth and business flexibility.
