So even though it was pretty mild, I still feel like it was inappropriate. I had a mid season evaluation a few days ago and my supervisor was mostly complementary. He did however say that some of my writing for the social media page was too long. I know that he has not personally read the content that I wrote but was instead told about it by my coworkers who have no supervisory authority over me complained about it to him. I feel like too much of the focus lately is on our social media anyway so maybe I’m a bit sensitive to it but I just felt that it was inappropriate for him to be getting material for my evaluation from a coworker.
