My company rented a local dance hall for a christmas party until 2 am. At 1:30, one of the guys starts mopping the floor without putting up signs or anything (it was also quite dark in there) and without knowing he had mopped where I was walking, I slipped and broke my hand. I don't really want to take this to court, but this surgery is costing me about $2500 cause a guy didn't put a sign up... Is this grounds for compensation?
