I think SIA should show maturity(as it always has)...
It has....?
Sorry, you are sadly mistaken.
SQ has always had knee-jerk reactions to expat air crew continued employment, and always will.
It has happened many times before, and certainly will again.
In my particular case (a very long time ago) I decided to move on elsewhere before the ax fell, and the monetary rewards in doing so were quite good indeed.
SQ is simply a pit stop toward a very rewarding career.... elsewhere.
