Effective August 1, 2006, unless the leave would unduly disrupt the operations of your agency, your agency shall grant you a leave of absence without pay if an immediate family member, as a member of the United States armed forces, has been ordered into active service in support of a war or other national emergency. Your agency may limit the amount of leave provided to the actual time necessary for you to attend a send-off or homecoming ceremony, not to exceed one day's duration in any calendar year. At your agency's discretion, you may substitute paid accrued vacation or compensatory time off for any or all of the leave period. Immediate family member is defined in the law as your grandparent, parent, legal guardian, sibling, child, grandchild, spouse, fiancé, or fiancée. See Minnesota Statute 181.948.
