I was replying to your attack on Slackie, who was correctly quoting what can be enforced. You may find that some regional controllers have been required to work recalls, or even change their off duty days to make the roster work.
Having stuck it out with Aunty Airways for 27 years and suffered the big losses incurred by it's Super scheme (-17% for a few years). I moved to pastures browner and now greener.
I now earn twice as much as I did with Aunty as a TMA controller (= I save twice as much), have more time off and work less.
You do the maths
