CRM has morphed into meaning (especially amongst CC) everyone getting on with each other.
A personal interpretation of CRM seen on some flight decks is where the first officer sees it as a legal chance to go overboard by questioning the captain's almost every operational decision.
And this is not about flight safety; but more about demonstrating the assertiveness power encouraged by CRM afficianados.
Example: captain asks first officer to ask ATC for approval to divert 20 miles right of track to avoid a storm. F/O argues the toss and says 20 miles too much and that 10 miles is sufficient. Later ATC says advise when clear to return to track. Before captain can say anything, F/O says we can regain track now. This is not only bad manners but poor discipline and an affront to the captain's responsibility for the safe conduct of flight. CRM is not open slather for tit-for -tat points scoring on the flight deck but it has gone that way. A captain who calls a halt to this attitude in no uncertain manner is accused of disregarding the whole raison d'etre for CRM.
