Got jumped by a student who tackled me to the floor with no provocation or warning--in fact I had just a few minutes prior encouraged her to take a break and use a fidget if she was getting stressed by the independent math work she was doing and had moved on to help other students. She used my manbun as a handle to beat my head against the concrete floor, concussing me badly enough it took a month for my words to stop slurring and six months of physical therapy before I could walk without assistive devices.

Union forced workman's comp to cover it, but I still have memory issues that I never had before that (this was years ago now) and surely it would have cost the school less to have some sort of preventative measures.
