You are not a Jetstar employee while you are training prior to induction. This is a very deliberate policy by HR to ensure that you don't have any claim against them if you don't pass the type rating or induction check flight. It is also why there is very little Jetstar content in the training but you are expected to be completely familiar with Jetstar procedures during the induction check. So from day one of your actual employment with Jetstar there is very little incentive or desire to embrace the whole "Jetstar family" BS.
