Question: Which Wisconsin state governor oversaw a vote to significantly limit public employee collective bargaining?
Context: Recall elections for nine Wisconsin state senators were held during the summer of 2011; one was held on July 19, and six on August 9, with two more held on August 16.  Voters attempted to put 16 state senators up for recall, eight Democrats and eight Republicans, because of the budget bill proposed by Governor Scott Walker and circumstances surrounding it.  Republicans targeted Democrats for leaving the state for three weeks to prevent the bill from receiving a vote, while Democrats targeted Republicans for voting to significantly limit public employee collective bargaining.  Scholars could cite only three times in American history when more than one state legislator has been recalled at roughly the same time over the same issue. Recall elections for four Wisconsin state senators were held during the spring of 2012.  Voters put four state senators up for recall, all Republicans, because of the budget repair bill proposed by Governor Scott Walker and circumstances surrounding it.  Democrats targeted Republicans for voting to significantly limit public employee collective bargaining.  Scholars could cite only four times in American history when more than one state legislator has been recalled at roughly the same time over the same issue.  The recall elections occurred on June 5, with May 8 being the date of the primary election. Tariffnemnda or the Collective Bargaining Board of Norway is a governmental board under the supervision of the Norwegian Ministry of Labour and Social Affairs.  The board rules on the universal extension of collective bargaining agreements.  Within fields where the board deems there to be a demonstrable problem of social dumping or similar exploitation of labor, the board has the authority to extend a collective bargaining agreement that applies to the field to any worker within that field, whether the worker is unionized or not.  In effect, this establishes a minimum wage within several fields covered by universally extended collective bargaining agreements, although Norway does not have a universally applicable minimum wage. The Journal of Collective Negotiations was a peer-reviewed academic journal which published articles regarding collective bargaining.  The target audience for the journal was academics, students, employers, workers, and collective bargaining negotiators.  It was published quarterly until 2008 by Baywood Publishing.  The journal was cited by the "Oxford Handbook of Work and Organization" as a critical journal in collective bargaining theory and issues.  A common textbook in Industrial and organizational psychology has cited the journal as one of two key publications in that very narrow field.  It also has been quoted by the National Labor Relations Board. The 2011 Wisconsin protests were a series of demonstrations in the state of Wisconsin in the United States beginning in February involving at its zenith as many as 100,000 protesters opposing the 2011 Wisconsin Act 10, also called the ""Wisconsin Budget Repair bill.""  Subsequently, anti-tax activists and other conservatives, including Tea Party advocates, launched small pockets of counter protests.  The protests centered on the Wisconsin State Capitol in Madison, with satellite protests also occurring at other municipalities throughout the state.  Demonstrations took place at various college campuses, including the University of Wisconsin–Madison and the University of Wisconsin–Milwaukee.  After the collective bargaining bill was upheld by the Wisconsin Supreme Court on June 14, the number of protesters declined to about 1,000 within a couple days. Sectoral collective bargaining is an aim of trade unions or labor unions to reach a collective agreement that covers all workers in a sector of the economy.  It contrasts to enterprise bargaining where agreements cover individual firms.  Generally countries with sectoral collective bargaining have higher rates of union organisation and better coverage of collective agreements than countries with enterprise bargaining. The 2011 Wisconsin Act 10, also known as the Wisconsin Budget Repair Bill, was 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 affected 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 exempted 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. The NFL Collective Bargaining Agreement (CBA) is a labor agreement which reflects the results of collective bargaining negotiations between the National Football League Players Association (NFLPA) and National Football League (NFL) team owners.  The labor agreement classifies distribution of league revenues, sets health and safety standards and establishes benefits, including pensions and medical benefits, for all players in the NFL.  The first collective bargaining agreement was reached in 1968 after player members of the NFLPA voted to go on strike to increase salaries, pensions and benefits for all players in the league.  Later negotiations of the collective bargaining agreement called for injury grievances, a guaranteed percentage of revenues for players, an expansion of free agency and other issues impacting the business of the NFL.  The NFLPA and team owners have negotiated seven different agreements since 1968. In February 2011, a series of public employee protests began in the United States against proposed legislation which would weaken the power of labor unions.  By March, eighteen states had proposed legislation which would remove some collective bargaining powers from unions, along with another five states which proposed legislation which would negatively affect unions.  The protests occurred when public employee unions mounted protests against legislation proposed by Republican governors such as Scott Walker (Wisconsin), Rick Scott (Florida), Mitch Daniels (Indiana), Sean Parnell (Alaska), Rick Snyder (Michigan), John Kasich (Ohio), Paul LePage (Maine) and Jan Brewer (Arizona) which, among other things, would strip public employees of some collective bargaining rights as well as require higher employee contributions to pension and health care plans.  The governors stated they needed these changes in order to cut state spending and balance the states' budgets.  The protests began in Wisconsin, then spread to Indiana and Ohio, with unions around the country rallying to show their opposition to the proposed legislation.  Several other states considered similar legislation.  Virginia, North Carolina, and Texas prohibit formal Scott Kevin Walker (born November 2, 1967) is an American politician who is the 45th and current Governor of Wisconsin.
