MADISON, Wis. (WHBL) - A federal appeals court has upheld the law which strips most public workers in Wisconsin of nearly all of their collective bargaining rights. That ruling was handed down yesterday. It’s the latest showdown in the two-year battle over the change Governor Scott Walker put on the table in February 2011, passed a month later despite huge protests and a group of Senate Democrats traveling to Illinois in a failed attempt to head off a vote. There are still several other lawsuits pending over the controversial Act 10. One is being considered by a state appeals court.
