Norma - did things change when they contractorised the ground crew?
It occurred just after I left but I can recall more than a few occasions when ALL our available GC's pitched in to keep the flight (and seconds under a certain wee Jock Chiefy) on state (WX gearbox change, double engine change in field etc). I also noted a 'commitment shift' in some of the younger aircrew I encountered (on Sea Kings) who were more interested in ISS, ATPL's or OU than keeping the flight 'on state' at all costs and some had an unfortunate willingness to snag the old girls!
