All true, but he'd talking about temp-to-hire (which I've done with success (well, I wasn't the owner, just the direct report of the employee). And the author of the article pretty clearly doesn't want to try to play the Permatemp game.
What is temp-to-hire?? I think the "temp" part is an extended probationary period, right? I don't think you could fire someone 45 days into a 60 day probationary period and then expect to not pay unemployment because of some agreement between the employee and employer. Does the concept of temp-to-hire exist as law or policy in any government agency?
Temp-to-hire is hiring a person for a temporary period say 3 - 6 months as a temp with the expectation that if everything works out they'll get a job offer at the end. If it doesn't then the contract is finished and they leave.
