Without any knowledge of Gama's specific ops, it's an air ambulance contract and by definition incredibly dificult to roster......your perception that it is a shambles is probably best interpreted as it's tricky and sometimes involves some firefighting, like all ad-hoc last minute rostering.
I assume I am talking to someone who has a good knowledge of airline ops management and am not patronising someone unqualified to comment?
I think if you cannot come up with something concrete, and your observations are based on a couple of pilots bar room end of a long day moaning you should be careful about tainting a companies reputation.
