There are several aspects of CRM to beware of.
Woe betide the FO who thinks he knows it all and fails to respect the experience of the guy in the other seat.
Woe betide the company who fail to deal honestly with all their crew and fail to give them honest appraisals of their promotion and career prospects, preferring instead to tell them "You should get your command with us inside five years" and then wonder why people leave after seven or eight.
Woe betide the skipper who fails to listen to his FO. Despite his lesser experience level, he has still passed the same base check and it is significantly less time since he passed the ATPL and type technical exams - he might have a valid point and you need to listen to him.
Woe betide the skipper who fails to use all the resources open to him when the fan blades start to exit via the jet pipe and the flight deck lights up like a Christmas tree, and prefers instead to turn it into a one-man operation.
And finally, woe betide the FO who thinks that, because the skipper offers to listen to him, it shows that as an FO he has the final word. CRM principles dictate that the skipper should listen to him and take his views into account. Thereafter, the skipper should make his decision, announce it to anyone who needs to know. All should then back the said skipper up in bringing the voyage to a successful and safe conclusion, because by then the time for consultation is over. The captain's decision is final. He needs, however, to make sure he's got all the facts and possible viewpoints (time permitting) before committing himself to something that may, with hindsight, be a little rash.
