Are labor unions good for workers and the economy?

I'll examine how labor unions affect workers and the economy — gathering recent evidence on wages, inequality, and growth.

Labor unions have both significant benefits and costs for workers and the economy, with research generally finding they are strongly beneficial for workers but mixed for overall economic growth.

1. Benefits for Workers

Higher wages and benefits: The most consistent finding is the "union wage premium."

> Labor unions raise wages for their members by roughly 10 to 15 percent compared to similar nonunion workers
The U.S. Treasury Department found the same range in a 2023 report:
> Unions raise the wages of their members by 10 to 15 percent. Unions also improve fringe benefits and workplace procedures such as retirement plans, workplace grievance policies, and predictable scheduling

In raw numbers, Bureau of Labor Statistics data from 2025 shows union members earned median weekly wages of $1,404 compared to $1,174 for nonunion workers. Other studies find unionized workers earn 10.2% more than their non-union peers, while the AFL-CIO reports about 25% more each year.

Benefits extend beyond wages to fringe benefits like health insurance, company pension and retirement plans, life and disability insurance. For example, 85 percent of unionized workers have access to paid sick leave vs 62 percent of non-union workers.

Job security and voice: Unions negotiate increased pay and benefits and create a formal dispute resolution process for workers. Most contracts require "just cause" for termination, requiring documented reason before firing.

They also provide a "collective voice" channel to flag safety hazards without risking jobs and produce highly skilled workers through registered apprenticeships requiring at least 2,000 hours of supervised training.

Lower turnover is a key worker and employer benefit, as union workers quit less often because they have contractual grievance procedures and protections against arbitrary termination.

Spillover to non-union workers:
> Unionization also has spillover effects that extend well beyond union workers. Competition means workers at nonunionized firms see increased wages too

Economists call this the spillover or "threat effect": when a unionized employer pays above-market wages, competing firms often raise their own pay to keep workers. Research covering 1980-2010 found declining unionization accounted for roughly a third of the overall drop in average hourly wages during that period.

2. Benefits for the Economy

Reduced inequality and economic resilience:

The decline in union membership is economically important: unions lift wages, reduce inequality, and shape how work is organized.

Historical periods of high union membership in the mid-twentieth century coincided with the most compressed income distribution in modern American history. By encouraging egalitarian wage practices, unions serve to reduce race and gender wage gaps.

Unions also contributed to economic growth and resilience by reducing overall inequality, which otherwise impedes growth if disadvantaged people cannot access resources to acquire job skills or start businesses. They can also boost businesses' productivity by improving working environments and by giving experienced workers more input into workplace procedures.

In some capital-intensive sectors, union labor was found to be 17 per cent more productive than open shop labour, construction labour costs were 16 per cent lower despite higher wages, and total project costs reduced by 7 per cent.

Consumer spending: Higher wages translate directly into household purchasing power, supporting housing, vehicles and local services and creating a multiplier effect. Multi-year contracts also provide counter-cyclical stability, holding spending steady during downturns when nonunion wages can be cut unilaterally.

Better standards for all workers, reducing income inequalities and ensuring workers receive a fair share, and economic stimulus by higher wages contributing to increased consumer spending are cited as societal advantages.

3. Costs and Drawbacks for the Economy and Workers

Higher business costs and competitiveness:

Critics argue trade unions can lead to higher labor costs, reducing competitiveness and potentially hindering job creation.

Reduced flexibility and growth effects:

On aggregate growth, some research 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 this misses distributional benefits.

Long-term costs include multiemployer pension plans where withdrawing employers owe a share of unfunded liabilities.

Bottom Line

For individual workers, especially lower- and middle-wage workers, unions consistently provide higher pay, better benefits, greater job security and a formal voice in workplace conditions.

For the economy as a whole, unions tend to:

The net effect depends on industry context. As private sector union membership fell from more than 30 percent in the middle of the 20th century to just 10.5 percent (6.4 percent private sector), and about 10 percent of wage and salary workers in 2025, economists debate whether the gains in equity and worker well-being outweigh the costs in efficiency and competitiveness.
