MADISON, Wis. (AP) — The Wisconsin AFL-CIO plans rallies Tuesday and Wednesday in Madison to protest a bill that would make Wisconsin a right-to-work state. On Friday, Governor Scott Walker backed a surprise move by Republican legislators to quickly vote on the bill, an action the likely 2016 presidential candidate initially said should be delayed to avoid re-igniting massive pro-union protests. Walker rose to prominence in 2011, when he pushed through a law that effectively ended collective bargaining for most public workers. That led to protests with as many as 100,000 people and a 2012 recall election that Walker won. On this bill, there’s a public hearing Tuesday followed by debate starting Wednesday. Wisconsin AFL-CIO Secretary-Treasurer Stephanie Bloomingdale couldn’t give an estimate on the size of the crowds, but said people are very concerned.
