My firm's written policy is that an employee will be paid for 10 days of jury duty service. I have an exempt employee who, by law, was mandated to serve more than 10 days. She had to serve 4 days a week and so was in the office 1 day a week. After the 10th day, the firm made her use her own vacation time. Towards the end of the year, because she had used up all accrued vacation, sick and personal time, she had to take days without pay to help her mother move to another state. Was, what the firm did, legal -- making her use her vacation time for jury duty service?
