I remember probably 10-15 years ago, maybe slightly longer, when I was still working and we all had to be called together for a chat. We had had the no sexism/racism chats well before of course so were wondering what now? We were told we couldn't use nicknames anymore, only people's real names. Some people were only known through their nickname as they'd been in the company so long and it was all everybody knew them as. Even if they wanted to carry on being addressed by their nickname they couldn't. They may not take offence but somebody hearing it might and report it. So no more Ginge, Dusty, chalky, big bird, smudger and any other weird and wonderful names were allowed. Madness.
