An employer may deduct nominal fees that an employee receives for jury duty, usually between $10 and $30 per day in states that provide them. However, an employer may not deduct any more pay from a salaried employee as long as the employee did some work during the workweek. For example, if an employee had jury duty for three days and then returned to work for two day, then the employee must receive all of their pay for that week, minus the nominal fee deduction. Or if the employee had jury duty all week but did some work from home the employee is also entitled to their full pay.
Hourly employees, on the other hand, do not have to be paid by their employer for jury duty.
