I for one would welcome the return of experienced Aus ATCs from OS. With the baby boomers starting to retire we need all the experience we can get.
I dont see why we need be punitive or snotty about them coming back on an increment commensurate with their experience either.
Even if it were possible to train a journeyman for less (and it isnt) there is still a world of difference between a new chum with 5 minutes experience and someone with 5, 10 or 15 yrs behind them.
One point of order though - forget about Approach ANSA, BIGHT group for you, BAROSSA at best but the approach jobs have a fairly long waiting list and the line starts somewhere behind me.
