Lurker@R5 you should see the contract given to crew who have come up to LHR. Although it states 'At the end of LWOP you will be entitled to resume a position with Qantas in the same catagory and base' it then follows on to state 'Qantas reserves the right to amend or WITHDRAW these conditions'.
So the promises in the contract aren't worth the paper they are written on.
