I asked a family member that is a payroll clerk for our local county government, and she said that on your Jury Duty card, there will be a person and their number for you to call with questions, usually called a "Jury Commission Secretary". Since it varies from state to state, they will be the one to ask about your local rules.

In our state, your employer must pay you your normal salary, but then you have to refund to them whatever you were paid for Jury Duty.

PS, if you get called for Jury Duty, get ready and read up! www.fija.org
