My boss (effectively) prohibits us from displaying negative emotions towards each other, as he pulls us aside to chide us when we do. I think the intention is to encourage more constructive conversations, but his bar for what he considers inappropriate is so low that it ends up stifling disagreements. We have a tough time making decisions because of it. It's also difficult to tell him about other problems I have, because if I show any annoyance, he'll criticize my tone. He, of course, gets visibly angry with people on our team on a weekly basis. It's driving me nuts to have to walk on eggshells all day.
