How a College Degree Can Increase Salaries for Union Members

A college degree does not guarantee a certain salary. Pay depends on many factors, including industry, occupation, location, experience and economic conditions. Still, national data continues to show a clear pattern: on average, workers with more education tend to earn more over time. 

College degree salaries can still matter for union members who are already starting from a position of strength. Union membership is associated with better pay over a career. Research suggests that long-term union membership can create substantial lifetime earnings gains on its own.

National Data Shows a Strong Earnings Pattern

In one major study, researchers found that men who spent their entire careers in unions were associated with about $1.3 million more in lifetime earnings than men who were never union members. The authors also noted that this effect was independent of educational attainment. 

However, a degree can add another layer of opportunity. The Social Security Administration highlights research showing substantial lifetime earnings differences by education level. In that summary, men with bachelor’s degrees earned about $900,000 more in median lifetime earnings than high school graduates, while women with bachelor’s degrees earned about $630,000 more.

Even after controlling for key social and demographic factors, the earnings difference between workers with a degree and those without remained large.

Shorter-term data points in the same direction. The National Center for Education Statistics reports that among full-time, year-round workers ages 25 to 34, those with higher levels of educational attainment generally had higher median earnings. Bachelor’s degree holders in that age group had median annual earnings of $66,600, compared with $49,500 for workers with an associate degree and $41,800 for workers whose highest level of education was a high school diploma (all numbers are from 2022).

Weekly Earnings Increase with Higher Education Levels

Information from the U.S. Bureau of Labor Statistics (BLS) shows a similar pattern in weekly earnings data for workers age 25 and older. In 2024, median usual weekly earnings were $1,543 for workers with a bachelor’s degree and $1,840 for workers with a master’s degree, compared with $930 for workers with a high school diploma. The same BLS table also shows lower unemployment rates at higher education levels.

None of this means every degree leads to the same outcome. Some programs have a clearer connection to promotions, management roles, technical specialties or career changes than others. Some workers may see gains quickly. Others may see the value built over time through access to better roles, stronger advancement potential or greater stability.

How Education Builds on Union Wage Advantages

For union members, that is an important point. The value of a degree does not replace the value of union membership, but it can build on top of it.

A union job may already offer stronger wages, benefits and protections than many nonunion roles. Against that backdrop, earning a degree can expand options further, whether that means qualifying for leadership positions, moving into a new field or strengthening long-term earning potential.

The careful takeaway is this: no college promises a bigger paycheck. But reliable national research does show a lasting connection between higher educational attainment and higher average earnings. For union members, the potential upside of college degree salaries may come in addition to the wage advantage that union membership already provides.
