I don't know about where you work but just think about the 1 repair you make which saves the boss a couple of bucks, the part fails, someone gets hurt & you're stuck holding the bag. Happens all the time. You may not be able to be sued BUT the knowledge of having hurt someone to save a buck combined with the fact that your boss may not be able to offer a good recommendation after an accident should be in the back of your mind.
Just some food for thought
