Sorry QANTASIC
QF is very conscious of legalities
neither internals or externals on the waitlist have been told 'they have a position once one becomes available' .... QF recruitment would never be that definite, not without a following clause along the lines of ' however if you are not called within xxx months, you will have to reapply.... ".
They never promise anything, and that is the smart legal strategy .... trust me - anyone who tells you they have some sort of legal claim against QF for not recruiting from the shortlist is seriously deluding themselves .... it has all been tried before, many,many, many times !!!
Sorry to burst a bubble, but also .... you think if anyone launches some legal claim against a large airline they would make it through training school without QF finding a reason for them to be fired??? methinks not .... it aint that hard
