Rananim is quite correct, SB.
The Captain, who has the modicum of social correctness, education etc, does not benefit much from the CRM courses now offered, IMO.
Said Captain has seen it all before while he was a First Officer, oftentimes operating under the authority of an overbearing Captain and, having the social correctness, education (etc), has long ago decided that he will not do likewise when he is the Captain.
About the only positive development of CRM is to teach others to get along with the overbearing Captain who is not going to change his ways, no matter how many CRM courses he is subjected to...ever.
Further, if a First Officer tries to use his CRM training to try to 'outrank' the Commander on occasion, he will many times find that the fleet manager/chief pilot is unlikely to appreciate same, and said F/O will be burning brides at a very rapid rate.
In short, he is likely to be 'stepped on', big time.
Just the way it is, in many airlines.
