This issue brief examines the impact of the law on Wisconsin’s K-12 public education system and state economy. While this brief focuses on Act 10’s impact on Wisconsin teachers based on the data available, the same forces driving changes in the teaching workforce can also affect the broader public sector.3 Proponents of Act 10 insisted that reducing collective bargaining rights for teachers would improve education by eliminating job protections such as tenure and seniority-based salary increases. As Gov. Scott Walker (R-WI) argued, “We no longer have seniority or tenure. That means we can hire and fire based on merit, we can pay based on performance. That means we can put the best and the brightest in our classrooms and we can pay them to be there.”4 However, the facts suggest that Act 10 has not had its promised positive impact on educational quality in the state.
The authors’ analysis using data collected by the Wisconsin Department of Public Instruction (DPI) finds that since the passage of Act 10, teachers have received far lower compensation; turnover rates have increased; and teacher experience has dropped significantly. Importantly, the harms from Act 10 extend beyond public-sector workers to all Wisconsinites, as current research suggests that student outcomes could be negatively affected by the law as well. Rather than encouraging the best and brightest students to become teachers and to remain in the field throughout their career, the law appears to have had the opposite effect by devaluing teaching and driving many teachers out of Wisconsin’s public schools.

Much more on Act 10, here.
