DETROIT (AP) -- Michigan workers can choose not to financially support unions that bargain on their behalf under a right-to-work law now in effect.
The measure that took effect at midnight will apply to labor contracts that are extended or renewed after Wednesday. Many unionized employees won't be affected for months or years.
Union organizers asked people to wear red Thursday to protest Michigan becoming the 24th right-to-work state.
And dozens did at a morning rally outside the Detroit Athletic Club, where Republican Gov. Snyder spoke to business and government leaders.
He told them that right-to-work is "done" and "over with" and called it "a significant milestone" that "will bring jobs to Michigan."
The governor says the new law "isn't about being anti-union," but is "about being pro-worker."
