If you’re injured on the job, you may have two separate kinds of cases. You definitely have a worker’s comp case under California law, but in addition, if there was someone other than your employer who’s at fault, you would also have a personal injury case.
The simplest example of this is: you’re driving in the course of employment, delivering something for your employer, when a drunk driver runs a red light and injures you. In that situation, you’re going to get worker’s comp benefits through your employer, but at the same time you have a personal injury case against the drunk driver. We deal with this issue all the time, and under California law the two systems mesh in a fairly intelligent way, so that you’re given protection on the short end by comp and then on the longer end by your personal injury case.
