On the night of the first Tuesday of every month, the accounting firm of Jones & Smith holds an "update session" for junior partners. This session is designed to keep accountants up-to-date on various changes in statues, regulations, and rules that impact them. Kelly, a junior partner, is a member of a religious group that practices druidism, a religion based on the practices of the ancient Celts. Because the religious group meets on Tuesday nights, Kelly does not attend the update sessions. Can Jones & Smith discharge Kelly for missing the mandatory meetings?
