A person may have jury service deferred if the person shows that jury service at the time for which the person is summoned will cause hardship to that person or another, that transportation problems make it temporarily impossible for the person to serve, or that the person summoned is employed as a full-time or temporary election official and the jury service is during the month in which a primary or general election is held. Jury service may be deferred under this section only if the person seeking the deferment agrees to a deferred date. Jury service may not be deferred for more than 10 months from the date the initial jury service was to begin.
