They cannot retrench people lah.
Government introduce job credit scheme to make sure that
retrenchment is kept to a minimum.
If SIA retrench, then some people up there no face.
Already the local bank retrenchment last year caused a lot of
unhappiness. 
Who says cannot retrench??? When SIA says something, it will do
it.
As long as "customers" not involved, loss of face = usual.
