What teachers can't wear in the classroom

Laws banning religious clothing used to be fairly common, but today Pennsylvania is one of just three states that prohibit teachers from wearing religious clothing in classrooms.

Court rulings in both Oregon and a federal court in Pennsylvania have rejected challenges to these laws by teachers and pointed out conflicts with the Constitution: Teachers have a constitutional right to freedom of religion, but school districts must avoid supporting any religion, according to the AP.

In Oregon, critics have objected to the measure there.
