I lost my cool after a co-worker sent an email calling out IT for not doing their job (totally unfounded, btw). When I went to investigate the issue, she confronted me and I snapped at her briefly. She contacted HR and I apologized in writing, stating I know it was unprofessional, inappropriate, and it won't happen again (which was the recommended course by my supervisor).
HR asked me if I wanted to do a sit down meeting with her to discuss our conflict, to which I responded no. It was a one time issue, I apologized, it won't happen again, and I considered it over. HR said they would tell her I wasn't interested in meeting.
Email from HR today requiring me to sit down and discuss with HR and the person I snapped at. Am I required to go? I'm not a fan on conflict (who of us are), but I'm not too happy that HR is forcing me to go sit in a room with the person.
