I was hired by the homeowner to be the general contractor. I then was asked If work was available by an individual... so he worked under me for 2.5 weeks. Week 1 his hours worked and time on jobsite were very confusing....but managed to get through it . Week 2 the individual submitted 20 hours at end of the week. As the general contractor I disagreed with his hours cause I knew there wasnt 20hours of work for the week. So after going over hours with the worker we came up with 8 hours actually worked. Worker was told of tasks he was allowed to do. And at the end of the week worker said his tasks were all done. By the weekend when I went to check work completed I found the work was not completed. And other tasks that were not mentioned were completed... sorta worker applied shingles to an area with out proper code materials.now more materials will need to be bought, and time to tear off and proper materials layied down then time to re shingle.... a cost that was avoidable. Now worker wants his money and is threatening to put a lien on property.
