Workplace bullying

Workplace bullying Hello everyone, As you can see from the title, I have felt bullied today at work. Today wasn’t not the first time. This is something I have been receiving from one specific individual who keeps laughing at my stutter. I speak to this person for business needs from different areas of the business and the last three conversations I had with her were very disgusting. I am not a person that confronts people with their behaviors towards me. I really don’t know what to do, what would you advice me to do?
