The First Amendment and Title VII of the Civil Rights Act of 1964 provide protection against religious discrimination by school districts against teachers. Teaches may exercise their religious rights, though there are certain restrictions to such rights. This existence of restrictions is particularly relevant to the public schools, since public schools are restricted from teaching religion through the Establishment Clause of the First Amendment. Thus, for example, a teacher is free to be a practicing Christian, yet the teacher cannot preach Christianity in the classroom.
