I dare say John, that that would no longer be the case.
Many mine workers have been sacked by their respective companies for unruly behaviour on their contract flights. A security guard contracted in by a mine operator to supervise the weekly gold run was recently removed from any flying duty after giving the flightie a spray because "she was the just flightie and wasn't gunna tell him what to do" (it was somewhat more colourful than that).
I know of about three mine workers sacked by their respective companies over the past four to six months due to unruly behaviour towards check-in and in-flight staff members.
