Your union contract probably spells out what holidays are observed. It also will outline the various types of leave—sick and vacation, perhaps parental and bereavement leave, even time off for jury duty—saying how much you’re entitled to and under what circumstances, and detailing procedures you may have to follow to use your leave. You may discover that there are types of leave contained in the union contract—such as the option of taking unpaid time off or adjusting your work schedule so that you can go back to school—that are used so seldom you weren’t even aware of them.
