What do you do when your boss refuses to pay you, I asked him to hold out taxes, or 1099 me. he keeps telling me the checks have not cleared the bank!

None of us filled out paperwork (taxes)and I found someone on face book that says he owes them money and owes a lot of others money also. Two other people have been paid but not in full. After looking around the place it seems to be unsafe, wires hanging from light switches, extension cords across the floor, expired food being repackaged and sold, the building is not in his name but he says he owns it and when I checked the county records there was some sort of paper stating something about fictitious names on the title. Jobs are hard to find and I am torn on what to do. He goes to area stores and purchases items, marks them up and re-sales them. STRANGE!
