I have not heard any rumours about 42 F/T positions. Far from it with the VR announcement. And if there were to be new F/T positions allocated there are many people in Eastern, Sunstate and Jetstar who are far more deserving of an internal transfer as they have been employed considerably longer than our MAM colleagues and have worked harder for longer in the QF group to have the right to progress to mainline.
Not saying MAM casuals don't work hard, but as flitegirl said I would hope they would action the progression scheme first.
