My son is a roofer. He was doing a job for his boss who pays him cash along with two other employees. His boss had no license or worker's comp. My son was using his bosses tools and was told by his boss the hours and days he would work. My son was using his boss's circular saw when it kicked backward and cut through my son's big toe vertically through the shoe, sock and the bone of the toe. He had to have surgery and was in the hospital for 4 days. Since his boss didn't have worker's comp or even a license, can my son file a claim on the homeowner? If anyone knows who would be responsible and how my son could get these huge hospital and doctor bills paid, please share your advice. Thanks
