Personally, I wouldn't have any issue with someone wearing a cross, or hijab, or a Star of David necklace in the workplace. But yesterday I saw a person at an amusement park wearing a shirt that basically said "My religion is the only way" (not in those exact words, but you can probably guess what it said). I would have an issue with a teacher wearing that in the classroom.
In the schools that my kids go to the teachers can wear a necklace or other piece of jewelry or clothing that is religiously-required, but no t-shirts with sayings on them.
