ive not been involved in ground handling dispatch for a while now, but the best way to tell was to look in the staff car park, look at the hardware the rampies drive to work compared to pax handling / dispatch!. .... the was quite a difference, we lost a few of our dispatchers to Ramp a number of times.
I normally drive an old banger in to the Staff Car Park at LHR , as i don't want the Roller to get dented in the car park !!!!
