There is a clause in the contract that allows for any other subsidiary that achieves over a "0/0/3/3" pay, the contract will revert back to a "equal amount" of the pay increase..
So if the engineering unit gets a ,3/3/3/3 the whole jetstar base will receive the pay increase and back pay across the board.
Let's hope this happens. Hopefully the engineering section is the best of all of us.
