I would cite the exact law that made religion a protected class in the american workplace: the Civil Rights Act of 1964. 56 years ago, this was happening often enough that Congress felt the need to act. This isn't a citation, but if you have a discussion with a jewish american over fifty years old, they likely have stories about this sort of thing.
