Having been lucky enough to attend an EK CRM course, and benefitted greatly from it, I am very much infavour of the old "Cockpit Resource Management" being retitled "Crew Resource Management" as is now the norm..
I learned very valuable techniques on how to pass my opinions to pilot/collegue/manager who just happened to be making a wrong decision without starting a row over it.
Pity the same techniques doesn't work with ex-wives.
It also didn't save me from loosing it one day with a Senior Flight Attendant, who just happened to be providing some horizontal entertainment to a certain senior management, and being "asked to resign" as a result.
