I don't doubt you mate, I for one believe Qantas is all the worse off for having made you guys redundant in the first place. Good on you for telling them to stick their job, if Qantas were an ethical company they would offer you guys your jobs back on a full time normal employment, instead they want you to become the wedge between the engineers, your former workmates. It could become as messy as the pilots strike, I for one wouldn't want to be on any list that would hinder my and my families life for the future.
There is a worldwide shortage of engineers at the moment, it is not the time to start accepting substandard pay rises especially since inflation has gone up past our pay rises, interest rates up, everything is up.
