MAS employ expats when they NEED them. Don't count on ANY security.
Contractors have been the go for the last 7-8 years and contracts have been cut short(tidal waves,earthquakes,any excuse)and they are used to it..
Great place to live if you are based at SZB not KUL.
Rates have been about mid to late 30's in USD tax free and minimum hrs 162. O/T is at same rate.
There is one contracting company to avoid if you want to get paid and not f'd around but you will quickly find out which one if you talk to someone there. The RAAF have a saying that mentions them.
EPF is very good if you can get into it.Bonus's may be paid to all bar you also.
Good luck.
