Any antipodeans reading will fondly remember the early days of Freedom Air in early 90's when all F/O's were told they were eligible for the next 737command slot and were then told to apply for the job with the renumeration they would expect. Obviously some wanted the command to get elsewhere while others wanted to stay a while.
It wasn't pretty, best and winning offer was under 20K sterling. Fortunately the process didn't transfer into Air NZ.
