Answer + Explanation:
Under Cesar Chavez's leadership, the United Farm Workers (UFW) used union contracts to improve the working conditions for farm workers by negotiating better wages, benefits, and health and safety standards for their members. The UFW leveraged its collective bargaining power to secure agreements with agricultural employers that provided its members with better working conditions, such as guaranteed rest and meal breaks, fair overtime pay, and protections against hazardous pesticides and other chemicals. Additionally, the UFW worked with the state and federal governments to improve the overall working conditions in the agricultural industry through legislative advocacy and public education campaigns. Through its efforts, the UFW helped to raise awareness of the challenges facing farm workers and paved the way for lasting improvements in the working conditions and rights of this vulnerable group.
