In 2011, Wisconsin became the focus of some controversy when newly elected governor Scott Walker proposed and then successfully passed and enacted 2011 Wisconsin Act 10, which made large changes in the areas of collective bargaining, compensation, retirement, health insurance, and sick leave of public sector employees, among other changes. A series of major protests by union supporters took place that year in protest to the changes, and Walker survived a recall election held the next year, becoming the first governor in United States history to do so. Walker enacted other bills promoting conservative governance, such as a right-to-work law, abortion restrictions, and legislation removing certain gun controls.
