Becareful with the 9 - 5 comparison. Try this:
Take your roster and calculate the times you work during Monday Friday 9 - 5. Then factor in the % overtime you would have recived during all the usually considered anti-social hours; weekends, night shifts public holidays etc.
Then look at your gross pay and calculate what the basic slaary is.
It will give you aperplexy and you'll wonder how you could have been ripped off for so long.
I believe during the nusres dispute ( which one) of many moons ago, when B. Cal still were going strong; the then chairman was asked to say what factor he included in crews salary for all the anti social hours and jet lag etc. I think he said 10 - 15%. In fact no-one had every thought about it. and such a lowly figure caused much humour. Still, nothing changed, did it?
