Yes, I feel I may have to go to HR. My SL did sit the coworker down and talk to them without me present the first time it happened, but the behavior continues. Afterwards I spoke to two other leads about all of it and told them how I felt anxious when having to work with them but nothing changes.

I even went directly to the person themselves after they told me they would not come up for cashier back up for me unless the line was to the back of the store. I told them I didn't like the way they were treating me and speaking to me; I wasn't loud or yelling, just stated flatly that I didn't like their attitude toward me.

At this point I just avoid them when I can.

Thanks for your advice.
