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 are asking people to wear red Thursday to protest Michigan becoming the 24th right-to-work state - a once-unthinkable change in a place where organized labor has played a central role.
Supporters plan to celebrate the law's passage.
Republican Gov. Rick Snyder is expected to see protesters at unrelated events in Detroit. He said Wednesday the continued political fighting, lawsuits and protests over right to work are "part of democracy" and he appreciates that "change is difficult for people."
