I was in our department office prepping for September at the end of the day. I'm the only female in the department. Several male teachers were in the room. I turned around when another teacher entered the room only to see my hod bare chested. He was changing to go home. I felt shocked that he would do that publicly with his staff members in the room with kids walking past the office. In private, I tried to tell him that it made me uncomfortable and that i would prefer he undress in the toilets in future. He dismissed it and said he hadnt meant for me to turn around and see and that was the least of my worries. Has anyone encountered a situation like this because he has made me feel very uncomfortable? I don't want to ignore it so he thinks it ok but i also want to maintain good relationships with my coworkers.
