Humpme, I think we've got crossed wires.
Your last paragraph was what I was trying to get at.
But to address your point about management training for captains. I think it's a good idea in principle. I didn't receive any specific management training but I'd have certainly benefited from it in the "early years"!.
Now I just tell it like it is and this sometimes those guys with the attitude get on their high horse about it.
On a parallel with your idea I think that proper CRM training for first officers is a must. The amount of times I've heard that "I can do what I want because of CRM" (I'm not joking) is ridiculous.
At the end of the day we are all there to achieve the same goal. Only ONE person is in charge but everyone is expected to do their own job to the best of their abilities. If they don't, can't or refuse to then they (should) end up with tea, no biscuits and we end up having these conversations!
P.s. I didn't mean to come across as patronising...I can speak better than I can type.
