Company I work for runs a course for us mere earthbound mortals. Not called CRM but "Management Skills Series - People" it's basically the same deal. Very usefull, also in the week-ends when you try to make a score on a babe in the bar. It's the bodylanguage thing, dead giveaway every time !!
Put briefly, it is of benefit to all who deal with people. Call it CRM or whatever, it teaches you basic and advance inter-personal skills, and god knows us dispatchers often needs to "persude" flightcrew to perform the way "we" like them to.
