...except the woman's reasons for not accepting the change was that she thought it went against her religious beliefs. That's NOT a valid reason to accept someone's change and quite frankly, I understand it's confusing for the kids in the class - but as a grown adult woman, she has the resources to educate herself and address the situation hands on. Religious beliefs are not in play when it comes to educating children, and as an educator, you need to be aware of the diaspora of kids you are dealing with.
Like she got fired because she can't do her job. Okay, they'll find someone who's better qualified for the position.
