Michigan Approves Union Curbs - Passing a right-to-work law in the state that the UAW union calls home is an especially deep blow to unions. They see right-to-work as political payback for unions' traditional support for Democrats.

From The Wall Street Journal:

The Republican governor of Michigan signed a pair of right-to-work bills Tuesday night, dealing labor unions one of their biggest setbacks in years in this historically union-friendly state.

The law won't go into effect until 90 days after the end of the state legislature's lame-duck session. Existing union contracts will only be affected as they come up for renewal, according to the governor.

While unions have been dealt setbacks in Wisconsin and Indiana, among other states in the industrial midwest, passing a right-to-work law in the state that the UAW union calls home is an especially deep blow to unions. They see right-to-work as political payback for unions' traditional support for Democrats.
