Yes the complete contract is on the Cathay website for employees to view.
I can break it down for you.
An SO on the old contract with full expat allowances after 3 years would be earning almost the same as a year 1 Captain on these new terms with the token housing allowance. Think it is about 10-15% less. (basic salary and housing)
Up until the point of becoming a Captain, which may take you 15+ years, a year 3 SO (2 years or more with CX) on the old expat deal would be earning more than you, basic pay and housing, if you join on this new deal. So after working for CX for 15 years, if you are not yet a CN you would be getting less, if upgrades go out to 20 years which they may do, you will be earning less than a 3 year SO. This is after working for CX for 20 years.
This does not take into account the far better education assistance the expat package used to provide.
Trying to put it simply as you seem to have trouble getting your head around what people are trying to say.
