Thai Social Network in Singapore
Singtip.com Just to share this site with you guys, they have a forum on jobs and housing, it's all in Thai though so I think you can get your Thai partner to check it out, maybe he/she will find something useful there. But actually if you want to find a job for Thai, good place to start is Golden Mile, I know that place is more famous for the nightspots but it's quite lively in the day, they have a supermarket, department stores, restaurant and some other businesses running, there's also translation services there at level 2 so it's not all that bad.
