Get this: In this jurisdiction, as an employer I have to legally continue to pay for the services of labor for another two weeks (at minimum, more if the worker has been around for a while) after I no longer want the service. That's thousands of dollars, possibly even tens of thousands of dollars, for a service I don't want.
Curiously, I have never yet met anyone who has politely declined or offered to pay it back. I suppose all workers are scammers by nature.
