Examples might include the unions of professional athletes, which have raised the wages of a certain class of already highly paid workers—professional athletes—but refuse to organize other workers, including other employees of the teams they work for. It commonly charged that the Air Line Pilots Association, the Screen Actors Guild, and a handful of other AFL-CIO unions conform to the labor aristocracy model of trade unionism. In defense of these unions, the AFL-CIO's jurisdictional rules may forbid such unions from organizing workers in certain occupational classes.
