Wisconsin is considering a bill that would prevent local governments from enacting worker-friendly ordinances relating to overtime, discrimination, benefits, and wages. On Wednesday, the Senate held a public hearing on the GOP-backed bill.

The bill, Senate Bill 634, would prevent local municipalities in Wisconsin from increasing the minimum wage, stop enforcement of licensing regulations stricter than state standards, and prohibit labor peace agreements (in which employers agree to not resist a union’s organizing attempts). The bill also specifically says that no city, village, or town can prohibit an employer from soliciting information on a prospective employee’s salary history, because uniformity on employer rights is a “matter of statewide concern.” Since research shows that women are paid less right out of college compared to male counterparts and there are large racial wage gaps, proponents of these ordinances say that prohibiting employers from asking about salary history could help narrow the pay gap.

Madison City Attorney Mike May told Wisconsin-State Journal in December that the “biggest impact” would be on protected classes under Madison’s Equal Opportunity Ordinance. If the bill became law, May said it would mean that discrimination based on student status, citizenship, and even being a victim of domestic abuse would all be “fair game for discriminatory practices.”

“This bill attacks workers, our rights and our democratic processes,” Stephanie Bloomingdale, secretary-treasurer for the Wisconsin State AFL-CIO, testified during the hearing. “This bill is about power, the power to overreach and tell citizens in their own communities that they don’t know what’s best for them.”

Wisconsin state Democratic senators Robert Wirch and Janis Ringhand voiced their opposition to the bill in statements on Wednesday. Both senators focused on how the bill could affect municipalities’ power to pass ordinances pertaining to sexual harassment.

“We need to be expanding avenues for victims of sexual harassment and assault to get justice, and not making it harder,” Wirch stated.

The committee didn’t take immediate action on the bill on Wednesday, but it’s still concerning that it’s being considered. Wisconsin Republicans have trifecta control of the state and have been successful in pushing a number of anti-worker bills through the legislature. Wisconsin Gov. Scott Walker (R) is nationally known for his long record of supporting anti-union bills. He signed bills that stripped the majority of Wisconsin’s public sector unions of their collective bargaining rights and made Wisconsin a “right-to-work” state, which means workers can decide not to pay fees to unions because the union has to represent them regardless.

The Wisconsin Counties Association, Wisconsin Council of Churches, League of Wisconsin Municipalities and some labor unions oppose the bill, according to the Associated Press. Americans for Prosperity, a conservative advocacy group funded by the Koch brothers, Wisconsin Manufacturers and Commerce, and groups representing various businesses support the bill.

Nick Zavos, government relations officer in Madison Mayor Paul Soglin’s office, told Wisconsin State-Journal that the mayor is “deeply concerned about the direction (the legislation) represents,” with particular emphasis on the preempting of local ordinances relating to employment discrimination.

Wisconsin is not an outlier in considering this kind of legislation. As city governments have pushed for better labor standards, states across the country have passed laws to preempt increased protections for workers. At least 15 states have passed 28 preemption laws like this one that cover labor issues such as paid leave, minimum wage, and fair scheduling, according to the Economic Policy Institute’s August 2017 report. As the report notes, historically, preemption laws were used to set minimum statewide standards for workers that local governments couldn’t lower. These recent laws are doing the opposite.
