MADISON, Wis. — Wisconsin Gov. Scott Walker has signed a contentious collective bargaining bill into law, but that doesn’t seem to matter to labor protesters in Madison.

Dozens of protesters arrived early Saturday morning, and tens of thousands more are expected to turn up for another day of demonstrations at the state Capitol. Clumps of protesters are already walking around the building, shouting “recall Walker.”

The bill Walker pushed strips public employees of most of their collective bargaining rights. Tens of thousands of people have been demonstrating against it for more than three weeks, and Senate Democrats fled the state to try to prevent its passage.

But the Republican-controlled Legislature passed the bill this week and Walker signed into law Friday.

The Senate Democrats are expected to return to Madison on Saturday.
