I used to work for a factory but I got burned on my arms and needed skin grafts. They've healed and I took some classes and went through vocational rehab to get an office job. When the COVID restrictions were dropped to the point we could open at 30%, some of us went back into the office.
Everything was fine until I was cleaning a cup one day and a coworker noticed the scars from the skin graft and we were talking about it. My coworker has tattoos that are called sleeves, I think and told me that would be a way to cover the scars if I wanted to.
Another coworker was walking by and tore into the first one saying that they shouldn't be talking about my scars and that they were going to go to HR and report them for harassing me.
I told the coworker that I wasn't being harassed and it wasn't her business and she said that I shouldn't let people walk all over me.
How do I tell this person to stop and what should I do if she goes to HR? My other coworker was only trying to help and I have thought that maybe they have a good idea because I looked up tattoos to cover scars and it does look like people are doing it.
I don't want my coworker to get into trouble. What should I do?
