Removal
In the USA if the Captain says your off.. then your off.. He might have to argue with management but if he/she sticks to ur decision. your off..Airplanes have a minimum FA crew to remain legal.. I retired off the 777 and we normally carried 12 FA's on international flights. Min FA crew is 9. if necessary the Captain can remove 3 and depart legally. It has happened to me 2 times in my career. Once I threatened 3 with removal if they didn't settle down (they did and were happy they did) and once I removed the Purser for good as we were downline. We went home the next day minus Purser which created more work for the rest of the crew but was a necessary decision based on the Pursers actions. The Purser was allowed to Dead Head home and was met by her supervisor.. I never heard a thing after.
