On Jobs: Wisconsin is open for business, via right-to-work law

The passage of right to work marked a shift in Walker's position. The governor said repeatedly during the intense battle over Act 10--his 2011 law that repealed most collective bargaining for public workers--that he would not let legislation affecting private-sector unions reach his desk.

Walker signed the bill at a Milwaukee area factory, saying it represented "one more big tool" for attracting businesses and investment to the state. "This sends a powerful message across the country and across the world," Walker said. "'Wisconsin is Open For Business' now is more than just a slogan. It's a way of doing business."
