Wisconsin construction apprenticeships are up; report says they could grow faster

Wisconsin saw the number of construction apprentices grow in the last decade, but a new report suggests that growth might have been stronger with some changes in Wisconsin law.
One change would be to restore the state’s prevailing wage law on government construction projects. The other would be to repeal Wisconsin’s “right-to-work” law — a measure that prevents unions from requiring all workers that they represent to pay union dues.
The report was produced by the Midwest Economic Policy Institute, based in La Grange, Illinois, and conducted jointly with the Project for Middle Class Renewal at the University of Illinois at Urbana-Champaign.
“While increased public investment in the construction sector is having a positive impact on the apprenticeship system, it is clear that state policy interventions that erode workforce institutions that prioritize training have had the opposite effect,” U of I professor Robert Bruno, director of the Project for Middle Class Renewal, said in a statement.
Bruno said that in addition to reinstituting Wisconsin’ prevailing wage law and repealing the right-to-work law, states can increase their investment in pre-apprenticeship programs to boost the foundational skills for skilled trades workers. He also has suggested tax credits to give more employers an incentive “to invest in our long-term domestic labor supply.”
Looking at data from 2022, the study’s authors found that unionized construction companies account for 22% of the construction market in Wisconsin. Despite that, apprenticeship programs operated jointly by employers and unions enroll 77% of construction apprentices and account for 96% of the money spent in Wisconsin on apprenticeship programs.
When it comes to training, “the unionized segment of the construction industry punches above its weight by a great deal,” MEPI economist Frank Manzo IV told the Wisconsin Examiner.
Funding advantage
Wisconsin also has certified construction apprenticeship programs operated by employers alone, but MEPI found that they enrolled only 23% of apprentices.
The investment in apprenticeship programs was similarly lopsided, the report finds. The spending on joint union-management programs totaled $64.3 million in 2022, compared with $2.9 million spent on the employer-only programs.
One reason for that gap is funding, Manzo said. Construction union labor agreements include a provision to cover the cost of apprenticeship programs as part of each worker’s total hourly wage and benefits.
“They’re funded by cents-per-hour contributions from employers that are used to train the next generation of skilled trades people,” Manzo said. “So, there’s always money for registered apprenticeship programs.”
By contrast, employer-only programs “rely entirely on voluntary contributions from those employers,” he said.

The study comes as the administration of Wisconsin Gov. Tony Evers is proposing an administrative rule requiring that contractors employ apprentices as 10% of their workforce on state projects.
“These are all areas right now when we’re looking at how we can provide quality, middle class jobs,” said Kent Miller, president of the Wisconsin Laborers’ District Council. The union represents a broad cross-section of construction workers.
“I’ve heard many times from members how an apprenticeship helped them get their first home,” Miller said. “As much as we can invest in Wisconsin workers it pays dividends down the road. That’s why the private sector union construction industry is making these investments in worker apprenticeship programs.”
Demands for skilled labor
MEPI’s study grew out of the nonprofit institute’s review of how states are responding to an increasing need for skilled labor.
“The construction industry is facing high demand for qualified tradespeople to modernize infrastructure, energy systems, domestic manufacturing facilities, and that’s really happening across the Midwest — across the Rust Belt,” Manzo said.
The research team expected to see Wisconsin among faster-growing states in apprenticeship enrollment. But while apprenticeship numbers have increased by nearly 50% from 2016 to 2024 in the state, “we found that this growth has actually lagged neighboring states that maintained policies that promote workforce training investments and policies that promote workers’ rights,” Manzo said.
The clearest correlation the researchers found was whether states required contractors to pay prevailing local wages on state-funded construction projects.
Just as a federal law known as the Davis-Bacon Act requires construction projects on federal facilities to pay prevailing wages, a number of states have similar laws for state and local government projects.
Contractors are hired for government projects typically based on the lowest bid. Prevailing wage laws require bidders to meet local wage standards, keeping them from cutting wages in order to win the contract.
The requirements “level the playing field,” said Miller, the Laborers union president. “It prevents out-of-state contractors from coming into Wisconsin, low-bidding taxpayer-funded projects, doing shoddy work and taking taxpayer dollars that we’d like to see stay here in Wisconsin.”
Wisconsin repealed its state prevailing wage law in 2017, however.
Encouraging training investments
The MEPI researchers found that in four nearby states — Illinois, Michigan, Minnesota and Ohio — the number of construction apprentices increased by just over 63% from 2016 to 2024. All four states have maintained their state prevailing wage laws in that period, according to the report.

Prevailing wage laws “ensure that all firms — regardless of union status, by the way — would commit to these cents-per-hour contributions into registered apprenticeship programs while performing work on public works projects,” Manzo said.
Wisconsin’s “right-to-work” law, enacted in 2015, might also be holding down apprenticeship growth, the study’s authors suggest. Such laws forbid employers and unions from negotiating contracts that require all union-represented employees to either pay union dues or pay a fee towards the costs of the union’s work representing employees.
The law “is a government regulation that forces unions to represent nonmembers for free and erodes worker bargaining power by reducing the resources that unions would otherwise have to organize and provide resources and advocate for investments in training, job site safety and job quality,” Manzo said.
As he has in every budget he proposed, Evers included in his 2025-27 budget plan provisions to restore the state prevailing wage and end the right-to-work law. Both were among more than 600 items that the Republican majority of the Legislature’s Joint Finance Committee removed on their first day of budget deliberations Thursday.
Restoring Wisconsin prevailing wage law and repealing the right-to-work law would create an economic environment in which skilled trades workers know they will be supported, said Jacob Heger, an MEPI research analyst and coauthor of the report.
“They can go into these apprenticeship programs, they can get the quality training that they need and then they know that in public policy they’re backed up by what’s on the books [in state law], and that the people in their state capitols have their backs,” Heger said.
