you could use Homejoy to find a good cleaner and then talk to them directly, they are a contractor and are free to make a contract with anyone they wish.
Because the more contractual arrangements they have the more the start looking like employees. FedEx is dealing with this right now with their contract workers.
I still don't see your point. Are you saying HomeJoy's cleaners don't have a contractual relationship with the company? That seems highly unlikely. I just expressed an interest in reading the terms of the contract that I assumet hey have, given that they're described as independent contractors.
