I understand the need for aesthetics but there has to be a limit. I side with the worker most of the times. As an atheist it may be complicated for me to understand why someone really needs to wear a hijab to work, but the basic premise is that, as a theist friend of mine said, for religious people not wearing their sacred symbols equates with not wearing panties or something like that. I don't like religion, but I can sympathize with the fact some people are just not comfortable letting something they like stay on the closet, and I don't mind people wearing it. I wouldn't allow it for safety reasons though, such as the case of the Muslim nurse wanting to cover her arms
