Great job but didn't get along with co workers - Coach Mentor Independent Health Employee Review

I and a senior coworker didn't get along, and that made work hard. As nothing was done to diffuse the situation because the coworker and supervisor knew each other. This put me in an uncomfortable situation, as this coworker made the job hard and would make snide comments on my teaching style, and she was older/more experienced than me, but she hated me but loved another coworker. I would guess because I was a rule follower, quiet/reserved, and didn't want the kids to get hurt as I had siblings there age. She only left me alone after I responded to her after one of her snide comments.
