The U.S. Supreme Court hears arguments Tuesday in an important case that tests how far employers must go to accommodate the religious views of their employees.
Not only does federal law make it illegal to discriminate in employment based on religion, but it also requires that employers reasonably accommodate the religious beliefs of workers as long as the accommodation would not impose an "undue hardship on the employer's business." But what is an undue hardship? Congress didn't elaborate, so the Supreme Court had to define the term.
