Thank you so much cici!
The performance evaluation already done. He re battled back and attached to the final documents, HR even didn't let me know. He just email me all documents. I check my email when I back to work from sick leave and saw that.
I laid off on Sep. 1, so I am free after tomorrow. and won't see him again. I consult a lawyer, she lets me file a worker compensation, but my friend told me if worker compensation denied, my private insurance won't pay any medical bill for my hand.So that's another problem.
