Wisconsin Has Largest Union Membership Decline In US After Walker's 2011 Reforms

From The Wall Street Journal, Opinion, "Wisconsin’s Reform Lesson: Scott Walker’s union reform has yielded huge political benefits:"

[Wisconsin Governor Scott] Walker’s 2011 reforms, known as Act 10, removed the ability of public unions to collectively bargain for benefits and required that unions be recertified every year by a majority of all members. The law ended the government’s role as the union’s automatic dues collector, and in 2015 Wisconsin also became a right-to-work state.

Given a choice for the first time, workers have left the union in droves. A recent analysis by the Milwaukee Journal Sentinel found that since 2011 the state has seen the largest decline in the country in the concentration of union members in the workforce. By 2015 union members made up some 8.3% of workers in Wisconsin, down from 14.2% before Mr. Walker’s reforms. The Badger State has some 187,000 fewer union members than in 2005, and the Milwaukee Teachers’ Education Association has lost some 30% of its members.

Unions still have clout but they must now operate on the same footing as other groups that represent member interests—such as trade associations—by providing services in exchange for financial support. [Emphasis added.]
