Reply To: wearing a yamulka in a professional setting

I was the only one who wore a Yarmulka when I worked in Chemical Bank in the seventies. I once said, that it indicates we have a burden on the head so we cannot do everything we want. I heard from Rav Shulman who answered the question, how big should a yarmuka be? He said, it should be big enough to cover your brain.
If his job depends on it, he can remove it in his work place.
