I had already acknowledged Atse's comments but there are other reasons too.
I'll spell it out for you: I could name an operator who I know abuses every rule in the book and bribes their ops inspector to turn a blind eye!
So FTL's never get scrutinised nor training records and many pilots for said operator are not legal. I am sure there are many others.
If the rules were enforced it would be a start and pressure would not be applied to crews to bend rules.
I agree though that for airlines the only way to protect T's & C's has to be through union representation.
