Tell your managers boss. If you didn't touch her at all she is at fault if you did first then you could possibly be the one to lose your job.
I know how to keep my cool but she touched my arm first I was cool threw it all she was the one like she wanted to fight I told the manager and the supervisor I feel like they really aren't careing to do anything about it
Is your job union? If so i would go to HR and have them get involved
Speak with your hr department if you have one.
File a complaint with OSHA they protect any employee who fears for their safety, i work in HR for a company and as managers they shouldve taken immediate action. Dont let this go for your safety and your baby.
