Under United States labor law, a private sector union can expel a member from the union for any number of reasons, so long as it provides the member with the minimum due process required by the Labor Management Reporting and Disclosure Act (LMRDA) and does not do so for reasons prohibited by law (such as the member's race or protected political activities within the union). The union cannot, on the other hand, use a union shop agreement to require an employer to discharge a member for failure to maintain membership in good standing unless that member has been expelled from the union for failure to pay uniformly required union dues and fees. If the union expels a member for some reason other than failure to pay dues, it effectively terminates any right it might have had to demand that the employee pay dues thereafter or request that the employee be discharged for failure to do so.
