In February 2011, Governor Walker, as he described it, “dropped the bomb” on Wisconsin’s public employees, the birthplace of public employee bargaining, by proposing a law (Act 10) which would eliminate the right of collective bargaining in school districts, cities, counties, and most of the public sector. Collective Bargaining Agreements provide employment security and economic security, as well as wage increases, fringe benefits, and as U.S. Supreme Court Justice Holmes said many years ago, an effective voice for employees in the workplace. Unions had achieved these rights and benefits in a half-century of bargaining. Ostensibly proposed to address an alleged budget shortfall, the Governor’s proposed Act 10 not only called for reductions in economic benefits for public employees (e.g. limits on employer contributions toward pensions and health care), but prohibited public employers from bargaining with nearly all public employees over any issue, other than limited wage increases, under which no employee could recover losses due to the increase in the Consumer Price Index. For example, under Act 10, teacher unions can no longer bargain over issues of school safety, class size, planning and preparation time, and health insurance; educational assistants can no longer bargain over salary progression, insurance coverage or training; clerical/technical workers can no longer bargain over work hours, vacation benefits or time off to care for sick children; and state workers can no longer bargain over whistle-blower protections. The intent of the Governor was to silence public employees on issues of primary importance to them and those they serve, and to eliminate their political activity. His stated extreme, no compromise, “divide and conquer” approach was to gain full power over employees. That resulted in MTI members walking out for four days to engage in political action. Soon thereafter thousands followed MTI members, resulting in the largest protest movement in State history.
MTI legally challenged Walker’s law and in September, 2012, MTI, represented by Lester Pines, and his partners Tamara Packard and Susan Crawford, prevailed in an action before Dane County Circuit Court Judge Juan Colas, wherein Colas found that most of Act 10 is unconstitutional. In ruling on MTI’s petition, Colas agreed that Act 10 is unconstitutional as it violates MTI members’ freedom of association and equal protection, both of which are guaranteed by the Wisconsin Constitution. This enabled MTI to bargain Contracts for its five (5) bargaining units for 2014-15. MTI’s are among the few public sector contracts in Wisconsin for 2014-15.
