Yes Skaz, I do agree that you have more than just a CRM problem, (I am inclined to include communications within CRM, by the way), it seems as though you have one real 'cowboy' at the top who should be removed or re-educated by your Aviation Authority, doesn't sound as though that is likely though, does it?
Which only really leaves you with one alternative, possibly not an easy one, but are there any other employers you can go to?
It is good that you air your problems here and maybe some others can offer their thoughts and possible solutions too.
