But, the problem is not every company will give foreigner the good salary package (which what you said 14% add on)...
Besides the CPF issues, the company even try to reduce my friend's salary on the date of contract signing .... the company said my friend not the Singaporean, so they not able to give the salary which both of them agreed in the interview...so they try to cut down my friend pay around 20% .....
My friend no choice.... so she have to accept this "stupid offer" since she already in Singapore and this is the only offer she have it on that time... and all the Working Pass was get ready and approved....
Actually, i got a lot of Others Complaint from My Foreigner Friends... which i can share with your further...All of them from different country, some even graduates from PhD in NUS....
So Foreigner be careful, when you sign the contract in Singapore .... read carefully and ask clearly....may be you can request the HR send you the Contract via email for your understand....before personally come to Singapore for Signing...
