Missouri law states that an employee is entitled to three hours off from work with pay in order to vote, unless the employee has 3 consecutive hours of nonworking time while the polls are open. The provision applies to any election in which the employee is eligible to vote.
Before election day, the employee should notify the employer that time off is needed, and the employer has the right to specify the three hours that may be taken off. No employee may be discharged or otherwise penalized for taking time off to vote (MO Rev. Stat. Sec. 115.639).
