i didn't see it mentioned above, but one of the big benefits of employee leasing is that you can essentially "fire" the employee at any time for any reason. You simply call the leasing company and tell them to not send that employee back anymore and to send another. Where an actual employee is protected my laws and can turn around and sue you if you fire him without fallowing proper procedure.
Why do people not respect us as they do other tradesmen? Because every Tom, Dick, and Harry doesn't think he can be a plumber or electrician!
