The Missouri Senate has approved legislation requiring public employee unions to seek annual consent to automatically deduct fees from members' paychecks.
The bill also would require the unions to seek consent for spending members' fees on political contributions.
Public safety unions representing first responders would be exempt and not have to seek consent from members under the Senate bill.
The Senate voted 24-10 along party lines Thursday to send the measure to the House. Republicans supported the bill, while Democrats voted against it. The House on Wednesday passed a similar measure that would only require consent to spend dues on political contributions.
