Heads Down,
Based on your posts, not only am I amazed that you continue to work in an environment that you so clearly hate, but also any investment put forward by Qantas to improve the work skills of someone that feels they are owed this could only be seen as a complete waste of time and money.
Qantas hired you to undertake a particular duty, and for that you are recompensed accordingly. I understand dubious decisions made by equally dubious management types have made aspects of your particular duty frustrating to say the least, but at the end of the day, they owe you nothing.
You sound neither motivated nor interested in remaining part of the group and I'm surprised you haven't made the company's decision to get rid of 1750 people a little easier by voluntarily reducing that figure to 1749.
If you hate the place so much, and it is obvious that you do, just go.
