Strange question but does this exist in thailand, i need staff ^^

good question.. I think I saw one at the Interchange 21 building(the one ontop of the sukhumvit MRT station.. 

Yes, it does exist. Here in Ubon it is at the labor department. Same location where I applied and renew my work permit.

Depending on what staff you are looking for, you may have better luck in facebook groups. Here in Ubon there are 2 or 3 Facebook groups where businesses post their job openings. We've had fairly good success that way...definitely better than with the labor department.
