I find it hard to believe that an established airline expects guys to accept a job without knowing where they are going to be based.
Who in there right mind will hand notice in to an employer without a clue where they are going to live and work with the new employer.
This shows a distinct lack of regard for the future employee and his/her family.
Most people will not expect to move around the country every few years disrupting kids education, wives careers..etc, nor should they.
If this is how things are at the start it doesnt bode well for the future.
