Utter tosh Dave Bloke.
Thanks flaps forty, succinctly put. Dave Bloke, just because the current offering is insufficient incentive to make the role of CC a career position does not mean that has always been the case. In fact, there are many of us who have battled our way through the promotion minefield because we wanted to make career out of this job. Otherwise we would have stayed as 'main crew' with none of the responsibilities and no accountability. There is a world of difference between that and the role of CSD believe me!
Perhaps when you have a moment you would like to tell us why you think it can't be a career!
