Jon Hyman, a defense lawyer, posts a nice piece about accommodating employees’ religious requirements. He discusses how not to provide religious accommodations: Disneyland refusing to allow a Muslim worker to wear a hijab, Burger King denying a Pentocostal employee’s request to wear a skirt instead of pants, and a New York University firing a worker who wore an "I love Jeus" lanyard. Then, he adds a more personal example. He is Jewish and he married a Catholic woman. Isn’t that an accommodation also?
It is not that hard to accommodate religious preferences. We are a nation of immigrants, after all. See Jon’s post here.
