roaming,
Qantas is not here to provide a transport service for cabin crew to go home to London to visit their relatives for Christmas. If 38 hour slips are in the company's best interest, and are safe for crew to conduct in relation to fatigue issues (techies have been doing them for years), then good luck to them. Just because they spoil someones visit to the English countryside or visit to Ireland is bad luck. Do it on holidays like most of the general population. Your job is to provide a service to the passengers on board the aircraft, have a rest, and then provide the same service on the next sector. That's what you are paid for. Not to gallivant around the world. If you can fit it in, then great. Otherwise, realise that the GOD's of long slips everywhere are over.
