A Cabin manager once said to me "but if we put in a fatigue report it will show that we can't cope" EXACTLY !!
Is it still the case the CA's can work longer hours than Pilots? That's aways been daft for the 'crew concept'. Either way, I have known of numerous occasions in various airlines where CA's have not been promoted because of sickness rates. Not with pilots, but why should CA's be pressurised & victimised with such a policy?
