Unless it would be an undue hardship on the employer's operation of its business, an employer must reasonably accommodate an employee's religious beliefs or practices. This applies not only to schedule changes or leave for religious observances, but also to such things as dress or grooming practices that an employee has for religious reasons. These might include, for example, wearing particular head coverings or other religious dress (such as a Jewish yarmulke or a Muslim headscarf), or wearing certain hairstyles or facial hair (such as Rastafarian dreadlocks or Sikh uncut hair and beard). It also includes an employee's observance of a religious prohibition against wearing certain garments (such as pants or miniskirts).
