ah.. sux me still not millionaire yet
i agree on mackiddo in this, can ask what industry u in ?
previously when i was on workpass, my co have a voluntary CPF contribution, mean if i decided to contribute my portion the employer match their share, after a 1 year, i decided to stop as i need the money to roll for my studies.
nowadays they return their portion back to u, ...mean if u have a better use of the money else where then nogo
with the tightenin of the work pass every year, PR offer comfort thou, if u P1 level then different story
but if u bordeline in WP/EP and in attractive industries, SG gov might oust u out and give the job to the local or PRC local hehe

Any idea what consist of 'attractive industries'? IT, Engineering? Just curious...
