In our country, we are fortunate to believe in freedom of expression and freedom of religion. The United Kingdom has similar views about this issue.

Here is an article I found from the UK that illustrates the way some people look at these freedoms there.

The article is the story of Shirley Chaplin, a nurse with the National Health Services in Exeter. Shirley is a Christian believer and has worn a cross since her confirmation nearly 40 years ago. Her employer has decided that she is not allowed to wear a cross to work because it is a religious symbol and religious and cultural symbols are not allowed within the uniform policy.

On the other hand, if you happen to wear a hijab for religious reasons, that is perfectly acceptable.

Read this brief article for some more details and a brief discussion on whether or not the hijab is required for those that practice Islam.
