The 2011 Wisconsin Act 10, also known as the Wisconsin Budget Repair Bill, is legislation proposed by Republican Governor Scott Walker and passed by the Wisconsin Legislature to address a projected $3.6 billion budget deficit. The legislation primarily affects the following areas: collective bargaining, compensation, retirement, health insurance, and sick leave of public sector employees. In response, unions and other groups organized protests inside and around the state capitol. The bill was passed into law and became effective as of June 29, 2011. Public employees exempt from the changes to the collective bargaining law include firefighters and most law enforcement workers. The bill was ruled to be constitutional by the Wisconsin Supreme Court in July 2014, after three years of litigation.
