Walker held up a photo of President Ronald Reagan, who had famously fired striking air-traffic controllers, and said his plan to sweep away decades of protections for state public employees in a stop-gap budget bill represented "our time to change the course of history."
"It was kind of the last hurrah before we dropped the bomb," he said.
The budget-repair bill, which would strip most collective-bargaining rights from 175,000 public-sector workers while imposing immediate benefits concessions, went public four days later. Walker, a Republican, called for passage in the GOP-controlled Legislature within a week.
Word of the bill's union provisions started to trickle out in press reports Thursday night, which for union chiefs and organizers began what one described as "a freakout of a long weekend."
