Wisconsin's Republican-majority Senate passed right-to-work legislation in late February, and the Republican-controlled state assembly is likely to do the same in early March. Gov. Scott Walker, a potential Republican presidential aspirant, has said he expects to sign the bill into law. Most right-to-work states are in the South and the land-locked West, but in the last few years Indiana and Michigan – typically known as blue-collar, "union" states – have also adopted such legislation. Wisconsin would be the third state in the industrial upper Midwest to go "right-to-work."
