So the Seventh Circuit held Friday in Laborers Local 326 v. Walker (7th Cir. Apr. 18, 2014).

Act 10 … prohibited government employers from collectively bargaining with their general employees over anything except base wages, made it more challenging for general‐employee unions to obtain certification as exclusive bargaining agents, and precluded general‐employee unions from using automatic payroll deductions and fair‐share agreements. The plaintiffs, two public‐employee unions and an individual union member, argue that these changes infringe their First Amendment petition and association rights. They also argue that Act 10 denies union members the equal protection of the laws.

The district court rejected the plaintiffs’ constitutional theories and granted judgment in Wisconsin’s favor. We affirm.

Running to an airplane, and can’t post more, but the opinion (linked above) is pretty readable. Thanks to Howard Bashman (How Appealing) for the pointer.
