I am a home owner who paid an hourly laborer in full for all hours worked then told him I have no more work for him. His work was very shoddy, he padded his hours, took 5 smoke breaks an hour, was very pushy and even started to work on things I did not hire him to do. There is work to be completed, but due to budget I will be completing myself. And fixing all his screw ups. I paid him in full for all the hours he "worked". I do not have the money to pay him to do the rest of the work. So basically he has been laid off. He's now threatening a mechanic's lien. Can he do that?
