An individual who is selected to serve as an election judge pursuant to section 204B.21, subdivision 2 may, after giving an employer at least 20 days' written notice, be absent from a place of work for the purpose of serving as an election judge without penalty. An employer may reduce the salary or wages of an employee serving as an election judge by the amount paid to the election judge by the appointing authority during the time the employee was absent from the place of employment.

The written request to be absent from work must be accompanied by a certification from the appointing authority stating the hourly compensation to be paid the employee for service as an election judge and the hours during which the employee will serve. An employer may restrict the number of persons to be absent from work for the purpose of serving as an election judge to no more than 20 percent of the total work force at any single worksite.
