The grass is not always greener on the other side of the fence!
If you absolutely hate your job at QF and can see no future there for yourself then it can be a fun, challenging, beneficial, career move to head elsewhere.
If you are not absolutely sure then consider the following.
Your current boss is directing new aircraft, new routes etc to Jetstar which is upsetting you and slowing, or halting any chance of career advancement. Your union and you are pretty much powerless to stop the above. It is not fair that any ones job should be put at risk or have their conditions or pay reduced at the whim of senior management. So you are considering packing up and moving to the middle east......
Rather than volunteer to help make QF more money by working harder and perhaps reducing overtime payments or what ever QF want from you (note I am not saying that QF are correct) and perhaps see a return to expansion, new routes, continuous promotion and a more fulfilling career for all, you are still considering a move to EK.......
EK is a middle eastern airline, where forming any kind of union is an offense.
People have gone to jail for trying it.
There is no voice of reason, no union backup or peer support. You will get what you get, when they give it. It will always be on their terms not yours, it is not your country either so do not think that you have the same rights as locals, because you don't.
You will fly close to maximum hours, minimum days off continually, with less crew than you do in QF, in a much more demanding environment. For the first time in your life you will live with the constant fear of fatigue and the possible jail time you will serve if you make a mistake because of it.
Perhaps it is time to consider bending a little at home and work with the company that you all once loved. It will take a lot less compromise and subservience than selling your skills to the highest bidder and becoming their slave.
I have done both and wish you guys all the best with your choices.
