Always will have a low attrition, STW?
Did you by any chance notice that expat crew don't get expat conditions anymore? And have close to zero chance of getting a base?
CX is only able to attract candidates thanks to its reputation.
And if the attrition is so low, they might as well reduce your conditions further, as you will probably never leave anyway...
What would you do if you had no housing?
I know I wouldn't stay.
