Court holds that Title VII does not protect volunteer workers after nuns are fired by Red Cross

A group of nuns sued the American Red Cross after they were discharged from their volunteer positions.  The nuns argued that the Red Cross discriminated against them and violated their constitutional rights of free speech, free exercise of religion, and equal protection.  The Court held that their volunteer association with the Red Cross did not constitute "employment" subject to Title VII of the Civil Rights Act and that in any event, the nuns failed to establish either disparate treatment or that they were discharged for their expressive conduct or sincerely held religious beliefs.
