Is it illegal to film someone who is harassing you at work? Today my co worker was verbally belittling me at work and I filmed it, and took it to my boss.

He told me that I wasn’t allowed to do film someone without their consent and that nobody “In this establishment” would ever want to see it. I have hard evidence. Should I go above my department to HR with this? Everything I brought up as a problem was dismissed by my managers and boss. I have reviewed my states laws and I am completely within my right to have recorded the conversation.
