My best friend hurt his back while on the job. He is an abulence driver and he hurt his back lifting up a patient. He told his boss about it, which did not file a report. My friend left this job after a couple of years, because his back hurt too much. My friend is really ignorant about a lot of things in life. He has no idea about workman comp issues and all. He has been to the chiropractor many times over the past few years, but he still complains of back issues. How long can my friend file for a workman comp case in the state of California? I really hate that he has to keep forking over money out of his own pocket, when the accident happened while performing his duties on the job...you know what I mean?
