Generally, if you are summoned to the courthouse you will be paid for at least that day. If you are actually on a jury, you will be paid for each day or part of a day the trial lasts. The minimum pay is set by the Legislature. Counties may pay more than the minimum amount, but never less. Your employer may also have a policy that pays your salary during all or part of your jury service.
Some counties also pay for some travel costs.
Employers must grant time off for jury service. They cannot discharge you if you give them reasonable notice of the summons. Policies vary among employers as to whether, or for how many days, they will continue to pay your salary during jury service. You should consult your employer as to its policy regarding paid jury service and bring that information with you to court. You may also be asked to return later in the morning or to recess earlier in the afternoon to accommodate the schedule of key witnesses or to give the court time to discuss matters with counsel such as motions and jury instructions, which the law requires to be heard outside the presence of the jury.
