Can a religious organization fire an employee on the basis of immoral behavior outside of work hours? Redhead, the Plaintiff in this case didn't think so. She took her case to court and tried to sue the church that ran the school on the basis of Title VII protection from pregnancy discrimination. Churches can impose scriptural or moral standards on their employees, and this case proves it. But to be fully protected by the civil courts, a church must enforce its morality code fairly and uniformly and not in ways that disproportionately and adversely impact persons (such as pregnant women) who are protected by federal or state employment discrimination laws.
