another FO here with the same story, worked to death nearly year 1, then only done 700-750 hours the next two years, if that. Now taking home roughly the same money that i was when first signed off on the line and getting full sector pay (second half of year one). That means I'm earning about 7 or 8 grand a year less than the equivalently experienced FO was 5 years ago pre 'optimised' roster and pre hourly flight pay (and before the senior FO grade was abolished).
Happy days.....
