The reason the ATCO's have a higher offer than others is because they are selling their AAVA agreement - not the ATSA's or the engineer's - why should they benefit? What if we had sold 6 days annual leave - would you like to have split that with all the other trade groups too? a few years ago we negotiated seperately for one deal which was voted through - so there is precedent for this.
For me - year 1 looks ok, year 2 should be looking the same (rpi+0.5%).......
