Are labor unions good for workers and the economy?

I'll examine how labor unions affect workers and the broader economy.

Labor unions have both positive and negative effects for workers and for the broader economy - research finds benefits for members and spillover benefits for non-members, but also costs for employers and potential trade-offs for overall growth.

Good for Workers

1. Higher wages and benefits:
Labor unions raise wages for their members by roughly 10 to 15 percent compared to similar nonunion workers.

Bureau of Labor Statistics data from 2025 shows the gap in raw numbers: union members earned median weekly wages of $1,404 compared to $1,174 for nonunion workers, though those figures don't adjust for occupation, industry, or region. When economists control for worker characteristics, the causal wage boost lands around 10 to 15 percent.

The U.S. Department of the Treasury summarizes: 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.

Labor unions have a mix of advantages and disadvantages for employees, employers, and society. For employees, the benefits include higher wages and better benefits, as unionized workers typically earn more and have greater access to retirement plans and healthcare compared to non-unionized workers.

2. Job security and working conditions:
Most union contracts require "just cause" for termination, meaning an employer has to show a legitimate, documented reason before firing someone. This contrasts with at-will employment and leads to longer average tenure.

Unions also provide a structured way to flag safety hazards without risking jobs, and union workers quit less often because they have contractual grievance procedures and protections against arbitrary termination.

3. Reduced inequality:
Unions serve to reduce race and gender wage gaps. And modern unions have broad representation across race and gender.

Historical periods of high union membership in the mid-twentieth century coincided with the most compressed income distribution in modern American history. Unions negotiate pay floors that disproportionately benefit lower- and middle-wage workers.

Research on executive compensation finds that firms with strong unions pay their CEOs less, which compresses the overall wage distribution within those companies.

4. Spillover to nonunion workers:
The economic influence of unions doesn't stop at the bargaining table. When a unionized employer in a region pays above-market wages, competing firms often raise their own pay to keep workers from leaving or organizing. Economists call this the spillover effect.

Importantly, the positive effects of unions are not only experienced by workers at unionized establishments. Other workers see increases in wages and improved work practices as their nonunionized workplaces compete with unionized ones for labor.

Good for the Economy - The Pros

Supporters argue unions help the macro-economy through:

Consumer spending and stability: When workers earn more, they spend more, supporting businesses those workers shop at, creating a multiplier effect. Multi-year contracts also amplify this effect during downturns because union wages are locked in for the contract's duration, so consumer spending from unionized households holds relatively steady even when the broader economy contracts.

Growth and resilience: In addition to supporting the middle class, unions contribute to more robust general economic growth and resilience. They do so, in part, by reducing overall inequality. Income inequality often feeds back into inequality of opportunity, which impedes growth if disadvantaged people cannot access resources to acquire job skills or start businesses.

Unions can also spur overall economic productivity by improving working environments and giving experienced workers more of an input into decisions that design better and more cost-effective workplace procedures.

Some research has indicated that labor unions improve productivity by providing training for workers, reducing turnover and improving labor-management communication.

Lower turnover saves firms recruiting and training costs.

Costs and Downsides for the Economy

1. Higher labor costs and market inefficiency:
The effects cut both ways: unions compress the wage gap and stabilize household spending, but they also increase labor costs in ways that can slow hiring and constrain business flexibility.

In general, most economists say, the ability of labor unions to raise wages above competitive levels has a net negative impact on society. To the degree that higher labor costs are subsequently reflected in higher product prices, wage increases will be transitory in real terms, disappearing as inflation eats into them.

2. Employment effects:
Although unions improve compensation for their members, they tend to limit the number of jobs in an economy. They can do so either directly, by enforcing a constraint on the number of workers that can enter a profession, or indirectly, by pressuring employers to raise wages. Having to pay higher wages will persuade employers to seek less labor-intensive production techniques and hire fewer workers.

Several studies have estimated that employment growth in union firms is from 2 percent to 4 percent lower than that in nonunion companies.

Other research finds although US unions have historically secured short-run pay gains, these victories often come at the expense of slower employment growth, fewer future job opportunities, reduced investment and productivity, and diminished firm growth and viability.

Companies respond to wage pressure by trimming R&D, cutting capital, reducing company growth, and ultimately shrinking jobs for unionized workers.

3. Productivity is mixed:
Other studies have found a negative union effect. Richard Freeman, a Harvard University economist, points out that union productivity effects tend to vary by sector. "About two-thirds of the studies show [improvement] and about one-third show there might be negatives," he said. "Your best guess would say it's a wash."

But even the studies showing productivity increases find that the higher wage costs paid to union labor exceed productivity increases, so "what is absolutely clear is that profits fall".

Seniority-based promotion systems and detailed work rules can slow management's ability to reassign staff or restructure teams quickly.

4. Costs to members:
Union members must pay dues, which can offset some of the financial gains. Workers are required to pay union dues/fees that some might rather not pay.

Critics argue powerful unions can lead to macroeconomic problems such as wage inflation and lost productivity due to strike action.

Context

Only about 10 percent of U.S. wage and salary workers belonged to a union in 2025, yet the economic footprint of organized labor stretches well beyond dues-paying members.
