If 411A meant that most airlines don't value enough their CC, don't train them enough and treat them like a replaceable item = don't invest in them and (out of greed and ignorance) are blind enough not to realise they are an asset, then he's right.

Speaking for myself, I usually think (I seldom cry) CRM when someone's attitude makes working as a team disagreable and ultimately difficult. At least it's what they teach at our annual CRM RT.
