Missouri lawmakers have sent Gov. Jay Nixon a bill that would require public employee unions to get annual consent from their members to deduct fees automatically from paychecks.
The House passed the measure 85-69 on Monday. It passed the Senate earlier this year.
The legislation would also require public employee unions to get annual consent from members to spend a portion of their fees on political activities.
Organizations representing "first responders," such as police and firefighters, would be exempted from the measure.
Supporters say the measure gives public workers more control over how their union fees spent. Opponents argue it makes it harder for unions to participate in the political process.
