Hundreds of Wisconsin?s public employees clogged a hearing for hours and camped out in the state Capitol overnight in a desperate attempt to delay action on Republican Gov. Scott Walker?s plan to strip away most of their collective bargaining rights. The measure would end collective bargaining for all state, county and local workers except for police, firefighters and the state patrol. Two floors below the hearing, dozens of University of Wisconsin-Madison teaching assistants and students surged into the Capitol rotunda late Tuesday evening, putting down sleeping bags and blankets. Many were still asleep on the floor when the hearing ended.
