I have heard from rumours that in CIA the F/A's tried to form an inofficial union last year. Ryanair retaliated and fired / moved to other bases several of the "ring leaders". As a result the F/A's went on a kind of strike and while still performing their safety duties, refused to sell food and other goods during flight. Again MOL retaliated and replaced a lot of F/A's there, with several getting sacked. This might have caused some of the pilots to be afraid of MOL.
