missterrible,
I will have to guess at what your question means. I presume it is rhetorical and that you feel that pilots who have voluntarily undergone training for a commercial licence and paid for it and possibly also for a type rating seem to feel that they are entitled to be employed and paid by an airline. Perhaps you also feel that they are wrong and that they have no such entitlement. If that is the case then I agree with you. Nobody has any such entitlement and nobody is owed a living unless they are employed and doing productive work in return for that living.
However, I am not aware of any such suggestion on this thread. The general point seems to be that Aer Lingus invited applications from suitably qualified pilots for employment in Gatwick. Some were successful and have already taken up their positions. Congratulations to them and welcome. Some others were offered positions, given course dates, and so served notice on their current employers of thier impending resignation only to find that their courses were cancelled and so they found themselves unemployed. A third group completed the selection process and were never told whether they were selected or not. All they seem to be asking for is a little common courtesy and simple good manners. It seems a reasonable request to me.
If I have misunderstood your point then I apologise. Perhaps you would explain your question if that is the case.
