It is not At All a Significant Issue.
Despite this fact, flight attendants do not run the risk of being fired if they miss a shift while they are scheduled to work. This guy, who was previously romantically involved with a flight attendant, claims that because of the strong union, it is possible to simply skip work without having to face any consequences for doing so.
In spite of the fact that he had a love relationship with the flight attendant in the past, he continues to assert this. The customers on board will be disgruntled, but the flight attendants will look at this as a chance to have some fun and break away from the monotony of their typical workday duties.
