i did it years ago, its ok if you get selected for a jury on the first day,but if you are not it can be a lot of hanging around and going to the court for no reason,but i think most tell the people not actually on a case to phone the night before to see they need to go to the court the next day, make sure you find out from your employer where you stand on being paid by them while your doing it, they have to sign a form stating if they will either just not pay you at all for the length of jury service, in which case the court pay you, or if they expect you to go to work the days you are not needed in court they then pay you for those days only and the court pay you for the days you are needed there.
