Singapore Expats

Hallo
Is there work permit for unskilled labour like restaurant jobs ?
Is that allowed in singapore to employ for foreignpeople under unskilled work ? like in middle eastern countires ?

I ask this since i have a friend who does not have much education but wants to earn some extra dollars . can i as a PR invite him to search for jobs here although he does not have good education ? and if he finds something , will the singapore govt issue any work visa for unskilled people ?

Is it possible ?

visa for unskilled people? dont think so wor..
work permit for unskilled labour sure got mah.. else how's our guys from other countries work here?
Restaurants in SG wont engage unskilled workers, unless ur friend knows how to cook n is damm zai.
