Thermal Image You are confusing locals lack of mobility which is totally different to an ex-pat having less job security. Yes as an ex-pat I can return home or seek a job elsewhere,whereas I recognise in Singapore you are giving up one hell of a lot by leaving. As PM Goh says are you a stayer or a quitter?? How about his daughter???
However in SIA Locals have permanent contracts and yes you can be terminated at 3 months notice but in practice this only happens to locals such as the SQ6 incident and say the A310- which went off the end of the runway at Kuching. In all other respects you are fairly safe in your employment.
As for SIA's reasoning behind terminating the SQ6 pilots we all know why they were terminated so what clause SIA want to put on it is really irrelevant.
I cannot believe that any locals will be terminated in the present crisis until all ex-pats have gone.
