It can include harassing an employee because of his or her religion. Harassment may include offensive remarks about a person's religion. However, the harassment has to be severe and pervasive. Teasing or isolated remarks would not qualify. Religious discrimination may also include refusing to hire or promote those who do not follow a certain religion. Employers may demote or terminate an employee who is of a religion that is different from that of the owners of the company. Segregation can also occur, but this is illegal, as well.
