Just to clear it up for everyone, QCCUK is not a labor hire company - it is a subsiduray used to employ long haul cabin crew to operate Q services. So being a subsiduray technically you are an employee of The Qantas group (eg: like Jetstar, Q catering).
In mainland Australia, the short haul division use a labor hire company to employ casual flight attendants. The labor hire company has nothing to do with the actual airline.
