Someone slammed into me on the highway and my boss is trying to cover it up

Someone slammed into me on the highway at 70 mph- and my boss wants to cover it up. Not report to Amazon, no option to claim L&I, no police report-and on top of that cut my hours down to ZERO & refused to sign a government paper stating proof of employment for me. The damage wasn’t that bad but I wasn’t at fault… so I’m being pushed out anyway??? He’s pushing me to quit since he cannot fire me. Do I stick it out and be miserable at work or just do us both a favor and leave? Or is there another option I’m not thinking of??
