Dolores Huerta and the late César Chavez are both credited with leading a movement that got growers to negotiate for better wages and working conditions for farm workers. Their legacies as United Farm Workers of American co-founders and leaders are now getting new attention after allegations emerged that Chavez sexually abused girls and women, including Huerta. Cornell University labor history professor Paul Ortiz says the movement's rise is one of the most important events in U.S. history and is the most important event in U.S. Latino history. He says agricultural workers had tried to organize for centuries but almost every effort failed until the success of United Farm Workers.
