If you are required to serve on a jury, your employer must give you the time off. However, we provide paid time off for jury duty with no maximum to encourage employees to be a part of the process. The daily money received by the employee while on jury duty (outside of childcare and parking expenses) are provided back to the employer to off-set costs.
The previous organization I worked for, Jury duty was paid time off with no maximum. All monies the employee received while on jury duty was paid back to the employer.
I am not sure what the policy is at my current employer.
