My wife slipped on steps in a building when attending an interview. The employee with her warned her to be careful because one of the steps was wonky, but the warning was just too late. She slipped and broke a vertebra, and since has had a back operation for the injury. Our medical insurance has covered most of the medical costs, with some exceptions, but she has had to cancel voluntary work she does and some international travel as a result. For an important forthcoming trip she will have to travel business class, at the advice of her physio. Is it possible in these circumstances to claim personal injury compensation?
