Are labor unions good for workers and the economy?

This question has extensive research behind it — I'll examine what unions do for workers and the broader economy.

For workers and the economy, unions have well-documented benefits and costs - most economists say the answer is mixed and depends on how you weigh them.

Benefits for Workers

1. Higher pay - the union wage premium
Labor unions raise wages for their members by roughly 10 to 15 percent compared to similar nonunion workers. When economists control for worker characteristics and compare workplaces that barely voted to unionize against those that barely didn't, the causal boost is around 10 to 15 percent.

In raw 2025 numbers, Bureau of Labor Statistics data shows union members earned median weekly wages of $1,404 compared to $1,174 for nonunion workers, meaning non-union workers' median earnings were 84% of what union members earned.

2. Better benefits and job security
Contracts frequently bundle in employer-sponsored health insurance and defined-benefit pension plans. Unionized workers are also significantly more likely to have health coverage. In states with higher union densities, the share without health insurance was 5.7% versus 9% in low-density states.

Most union contracts require "just cause" for termination, meaning an employer must show a legitimate, documented reason before firing someone. This leads to much longer average tenure.

Unions also provide training through registered apprenticeships that require at least 2,000 hours of supervised on-the-job training and give workers a structured, collective voice to flag safety hazards without risking their jobs.

3. Lower turnover and spillover to nonunion workers
Lower turnover is one of the clearest gains. Union workers quit less often because of grievance procedures and protections, which saves firms recruiting and training costs.

Wages also spill over: when a unionized employer pays above-market wages, competing firms often raise pay to keep workers from leaving. Research covering 1980-2010 found declining unionization accounted for roughly a third of the drop in average hourly wages, with about two-thirds of that decline from weakened spillover pressure on nonunion employers. Nonunion employers have an incentive to match union wages to avoid an organizing drive - the "threat effect".

4. Reduced inequality
Historical periods of high union membership coincided with the most compressed income distribution in modern American history because unions negotiate pay floors that disproportionately benefit lower- and middle-wage workers. Research also finds firms with strong unions pay their CEOs less, compressing the wage distribution within companies.

States illustrate this: between 1979-2024, median wages rose more in states where unionization declined less, the productivity-pay gap grew more slowly where union decline was smaller, and in 2023 median household income was on average more than $12,000 higher in high-union-density states than in low-density states.

Benefits for the Economy

Higher wages translate directly into household purchasing power, creating a multiplier effect as union households spend on housing, vehicles and local services. Because collective bargaining agreements typically run three to five years, union wages are locked in and consumer spending from union households holds relatively steady even when the broader economy contracts, providing counter-cyclical stability during downturns like 2008 and the pandemic.

Some research indicates unions can improve productivity by providing training, reducing turnover and improving labor-management communication, though other studies find a negative effect and Harvard economist Richard Freeman noted about two-thirds show improvement and one-third show negatives, suggesting "it's a wash".

In high-union states, broader community benefits have been documented: higher unemployment insurance recipiency, higher education spending per pupil, and more paid sick leave legislation.

Costs and Drawbacks

For workers:
Labor unions cost members money, restrict individual earning potential, and impose rigid operating rules. Those advantages come at a cost: dues that typically run 1 to 2 percent of gross pay, less room to negotiate individual deals, and a seniority-driven system that doesn't always reward standout performance. Members also bear strike risks.

For businesses and the broader economy:

Only about 10 percent of U.S. wage and salary workers belonged to a union in 2025, yet the footprint extends beyond members through spillovers.

Bottom Line

For individual workers, particularly low- and middle-wage workers, unions on average deliver higher pay, better benefits, and more job security, at the cost of dues, seniority rules, and less individual bargaining freedom. For the economy, they compress inequality and stabilize consumer spending, but increase business costs, can reduce hiring, investment and flexibility, and modestly dampen overall GDP growth while shifting more of that growth to workers.
