Apparently, a few states offer jurors additional compensation in order to prevent jury duty from becoming a financial hardship. For example, in Colorado, jurors can claim financial hardship and seek additional compensation from the court. The Colorado law (13-71-125) on this issue reads as follows.
The compensation and reimbursement policy of this article shall be to prevent, insofar as possible, financial hardship for any juror because of the performance of juror service. Where financial hardship exists, the court shall attempt to place the juror in the same financial position as such juror would have been were it not for the performance of juror service.
