Next week, my family and I take off for a family wedding in Las Vegas. My mother works at a major league baseball field as a retail supervisor. She requested the time off before the baseball schedule had been established, and her time off was approved. However, 7 days before we leave, her PTO has now been revoked due to a very popular opposing team playing those days. She has already paid for the trip. Should she request to be reimbursed for the value of the trip? Should she protest due to the fact that she was approved prior? I feel that as soon as the schedule was established, they should have revoked the time off; not one week prior.
