Why did chavez organize marches? to what were they trying to draw attention?

Mexican-American farmworker, labor leader and civil rights activist César Chávez brought about better conditions for agricultural workers. Born on his family’s farm near Yuma, Arizona, Chávez witnessed the harsh conditions farm laborers endured. Routinely exploited by their employers, they were often unpaid, living in shacks in exchange for their labor, with no medical or other basic facilities. Without a united voice, they had no means to improve their position. Chávez changed that when he dedicated his life to winning recognition for the rights of agricultural workers, inspiring and organizing them into the National Farm Workers Association, which later became the United Farm Workers. Through marches, strikes and boycotts, Chávez forced employers to pay adequate wages and provide other benefits and was responsible for legislation enacting the first Bill of Rights for agricultural workers. For his commitment to social justice and his lifelong dedication to bettering the lives of others, Chávez was posthumously recognized with the highest civilian honor, the Presidential Medal of fdom.
