Work in team of 4 in a classroom. Job stressful, very enjoyable. 1 person giving us silent treatment. This person upset/angry that I didn't tell them myself that I got promoted. They have no interest in higher role. Silent treatment last Wednesday and Thursday, they refused my offer to talk on Thursday.. On Friday I spoke to person who turned their back on me whilst I was talking, I apologising for hurting their feelings... Today silent treatment all day, I again apologise via private message. Read message but no response .... I think I've done a that I can and I can't anything more... Anyone else had such drama? The person early 50s, me a few years younger
