The United Students Against Sweatshops, an organization of students and labor activists, successfully organized a boycott of Nike products to force a Korean-owned Kukdong factory in Mexico to improve working conditions. The Mexican workers drew attention in January when they staged a sit-down strike that ended when riot police ejected them from the plant. The student movement resulted in an investigation by Nike who convinced the factory owners to improve conditions, but the workers are still fighting for union representation.
