Study: Collective Bargaining Boosts Economy and Strengthens Public Budgets

Union agreements don’t just benefit members, they strengthen communities in era of uncertainty


La Grange, IL:  An analysis of eight construction industry collective bargaining agreements (CBAs) in the Chicago metropolitan area details how unionization extends benefits far beyond the paychecks of represented workers.  The study, conducted jointly by the Illinois Economic Policy Institute (ILEPI) and the Project for Middle Class Renewal (PMCR) at the University of Illinois Urbana-Champaign, concludes that CBAs boost the region’s economy by billions of dollars each year, create tens of thousands of jobs, improve social outcomes, and add hundreds of millions of dollars to public budgets strained by the COVID-19 pandemic.

Read the Report, “The Economic and Fiscal Impacts of Collective Bargaining Agreements in Construction A Northeastern Illinois Case Study.”

“While much is known about the impact of collective bargaining on the wages of represented workers and the apprenticeship programs that train most of our state’s skilled construction workforce, this report details broader economic, fiscal, and social impacts that are too often overlooked by policymakers,” said study co-author and ILEPI Policy Director Frank Manzo IV.  “In northeastern Illinois alone, construction union contracts aren’t just reducing poverty, they are creating jobs and spurring growth across all sectors of the economy while providing state and local governments with a reliable tax base to fund schools, police, fire, and other vital public services.”

The report reviews and analyzes collective bargaining agreements between the Mid-America Regional Bargaining Association (MARBA), a multi-employer association of union contractors, and eight construction trades unions representing 97,234 skilled trade workers in the Chicago metropolitan area.  It includes comparative analysis using U.S. Department of Labor, U.S. Census Bureau, and American Community Survey data. Overall economic and fiscal impacts were assessed using industry-standard IMPLAN modeling software.

Overall, researchers found that induced consumer spending resulting from wages paid under the CBA’s added more than $8.2 billion to the region’s economic output, creating nearly 50,000 additional jobs across other sectors paying an average wage of over $58,000 per year.  All told, the direct and induced effects of the agreements generated over $1.6 billion in income, sales, and property taxes for state and local government.    

“To truly understand the importance of these CBAs to the region and to Illinois, we set out to examine what would happen if these agreements were not in place,” added University of Illinois Professor and PMCR Director Dr. Robert Bruno.  “In addition to dramatic reductions in wages and health care coverage for represented workers, we found that the region would have created 13,000 fewer jobs, economic output would shrink by over $2 billion, and the state and local tax base would contract by more than half a billion dollars every year.”

In addition to the economic effects of these eight agreements, ILEPI and PMCR researchers also reviewed a decade worth of economic data on the Illinois construction industry to assess broader impacts of unionization– including effects on poverty, health care coverage, welfare reliance, homeownership, and even marriage.

“The data underscores the fact that collective bargaining agreements in the construction sector are producing benefits that extend far beyond the individual paychecks of represented workers,” added ILEPI Policy Researcher Jill Gigstad.  “And as Illinois emerges from the COVID-19 pandemic, policymakers should consider this industry’s experience with collective bargaining as a way to promote more family-sustaining careers, economic growth, and improved social and community outcomes.”
