Geez, who would have known that this would turn into such a phallic argument!
Personally I think the term 'On Board Manager' is indistinct, ambiguous, pretentious, and has delusions of grandeur for the position it alludes to. That's got absolutely nothing to do with the importance or otherwise of the role of the position the term is being used for. I'm more than comfortable with the lines of responsibility and authority on the aircraft. I'm also more than comfortable that the term CSM or FSD is a much more descriptive and appropriate term. Whilst I admire the job our cabin crew do (there is no way I could go through what you guys deal with) there is one 'on board manager' in law and it ain't the CSM, FSD or whatever term we want to use this week.
For the sensitive souls though, how would you feel were the Techies to start using the term 'on board management team'? Would you feel that excludes the CSM from being considered part of that team? See the point?
