Alot of the times they just run ads in the paper to collect resumes so they can check them out for potential companies to hit up. The London Ontario Kelly's office is the absolute bottom of the barrel. They have a fancy facade and act professional to your face, but behind your back they do everything possible to screw you over.
Avoid them like the plague. I'd rather work a minimum wage job than work for Kelly Services where they take more than half my wages. - When they were supplying slaves to Intier Automotive out behind the Flying J, they were paying people 12 while the temp service was getting 25 bucks an hour. Previously the temps were getting 15, but the people at Kelly's renegotiated the contract. No surprise that everyone quit and they had to shuttle people out in cabs!
