An appeals court in Wisconsin has restored a 2011 anti-union law that banned collective bargaining rights for public employees, setting up a challenge in the state's liberal-controlled Supreme Court. In practice, Act 10 required state employees to take pay cuts to keep pensions in place, and forced workers to increase their health insurance contributions. It also ended collective bargaining for public employee labor unions, although it exempted police, firefighters and sheriff deputies. An analysis from the nonpartisan Wisconsin Partisan Forum also found that Wisconsin had seen the largest decline in unionized workers of any state between 2000 and 2022. However, Act 10 has still remained in effect since then pending the appeals process, which will likely culminate in a final decision in the state's highest court following the latest decision that upheld the bill.
