In fact, I volunteered to work as cabin crew out of professional courtesy to my employer who asked for my help. I do not care about trade unionism nor do I believe I have any professional solidarity with or obligation to a group of workers who refuse to negotiate with BA for a year and then try to dictate silly terms that don't begin to address BA's business plan.
To put that in a few words "I just care about myself and my pension, sod everybody else"
