Flight Attendants unable to report for duty for longer than 21 days are required to notify his or her Flight Service Manager and provide medical documentation. This is generally not a problem for work injuries because your doctors must provide medical documentation to the insurance company concerning your injury or illness. It is possible, however, that you may need to get copies of the medical notes themselves and provide them to your Flight Service Manager. If you expect to be disabled for an unknown duration, you need to notify Crew Schedule.
