The sad thing about all this is that it is happening - as 411A says - because it can.
This is the way aviation is going, MOL is just the pioneer of these sorts of tactics.
It used to be that pilots were treated like senior execs. The main reason being, apart from their skill, that any one of them could seriously damage an airline by allowing a single lapse in professionalism. Many airlines have gone broke after a single crash.
Treating pilots like this will eventually lower the standards of the profession, and I personally think that it is only a matter of time before a Ryanair pilot, preoccupied with MOL's latest antics, has an accident. That is the inevitable result of raising the stress level in your pilot workforce.
Having said that, everybody has the right to vote with their feet. Ryanair pilots need to either grow some collective courage and take the company on, or accept their lot and quit grumbling.
