Business Law question

Mohen is a member of the Sikh religion whose practice forbids cutting or shaving facial hair and requires wearing a turban that covers the head. In accordance with the dictates of his religion, Mohen wore a long beard. He applied for a position as breakfast cook at the Island Manor Restaurant. He was told that the restaurant’s sanitary and good grooming reasons and that he would have to shave his beard or be denied a position. Mohen contended that the restaurant had an obligation to make a reasonable accommodation to his religious beliefs and let him keep his beard. Is he correct? (a couple of paragraphs should do) Thank you.
