Believe one global recruit in resignation letter pointed out, amongst other points, unsafe staffing levels and overwork as a factor in not wishing to continue. Management have been horrified by the comments and are taking "real" notice. Of course a controller from O/S would be able to assess the Oz situation and be recognised as an expert far more than the mere plebs who have been working the system for years and who just complain for the sake of blowing hot air!!
