I manage a team and work in a large, open plan office. Today a member of staff came to talk to me wearing just socks (and clothes thankfully).
I told him to go back to his desk and come back with his shoes on. He seemed shocked and asked me if I was joking and that he was "trying to relax."
I replied: "You aren't here to relax, you are at work so put your shoes on."
This is the second time I have spoken to him about this, the first time I did it in a more casual manner but he seemed genuinely surprised that I cared whether he had his shoes on.
The dress code is usual suits, shirt and tie for men and smart office for women.
So, AIBU?
