Look for another job just in case things don't work out with this major boss as a last resort or next resort, whichever you feel is best. Then you can write another letter explaining why it didn't work out, do name names... *snickers* Just remember, you didn't get the boss into trouble.. she got herself into trouble with misusing her authority to show unprofessional and unwarranted displease and it's her own damn fault.
Just in case this is a misunderstanding, maybe your boss didn't realize you felt this way... and could be happy to talk with you about it. She might not mean to make you feel bad. It could be worth a shot to ask her about your injury, and watch her reaction. Then report a bad reaction or overreaction to the human resource dept!
If you feel you are truly intimidated by your boss, you can see if you are being bullied and how to recognize a bully with this list.. Most people only realize they're being bullied when they read this page; what is bullying, how to recognise bullies and injury to health
Print it out and check all that applies to you. Maybe you can show it to your human resource with a letter, and don't name names.. see what they have to say about the person "bullying" you. It's likely you're not alone.. your boss probably does this to other co workers.
