One further thought, it has always been my view that the morning I wake up and don't want to go to work, or hate my employer that I move on. I am simply amazed at the attitude of some of the staff here and how much they hate the company that employs them. If you dont like working there go find another job.... its not rocket science.
And here is the rub. There are many old-contract senior CC that simply would not be able to get a job in another airline/service industry for comparable T&Cs as they have with BA. They would be competing against people who are younger, more eager, and cheaper.
A complete career change is also naturally difficult for anyone who has been in a particular industry for a long period of time, not least one such as aviation which is very different to 9-5 work.
