Cesar Chavez Day is a U.S. federal commemorative holiday, proclaimed by President Barack Obama in 2014.[1] The holiday celebrates the birth and legacy of the civil rights and labor movement activist Cesar Chavez on March 31 every year. The City of Phoenix celebrates the contributions and legacy of Cesar Chavez. After years of civil rights work in California, this American labor rights activist made his way back to Arizona where he fought for the improvement of working conditions for farm workers. This included a 24-day hunger strike bringing national attention to the inhumane conditions farm workers endured. As a reminder, City of Phoenix offices are closed on March 31st, each year in observance of Cesar Chavez Day.

Rising from the status of a migrant worker toiling in the agricultural fields of Yuma, Arizona, to the leader of America's first successful farm workers' union, Cesar Chavez was described by Robert F. Kennedy as “one of the heroic figures of our time.” Although by nature a meek and humble man known more for his hands-on leadership abilities than his public-speaking talents, Chavez appealed to the conscience of America in the 1970s by convincing seventeen million people to boycott the sale of table grapes for five consecutive years. Chavez's United Farm Workers Organizing Committee (UFWOC) spearheaded the drive for economic and social justice for Mexican and Mexican American farm workers. A cross section of Americans supported the cause, including college students, politicians, priests, nuns, rabbis, protestant ministers, unionists, and writers. By forming one of the first unions to fight for the rights of Mexican Americans, Chavez became an important symbol of the Chicano movement. - Russell, Dennis. "Chavez, Cesar (1927–1993)."

In the 1960s and '70s, Cesar Chavez and farmworker activists formed an alliance with musicians and artists to help build a movement called "La Causa". A SONG FOR CESAR tells the story of that alliance using first person accounts of artists, musicians, members of Chavez's family, and other key figures of the movement. Inspired by the spirit of the thousands of farmworkers who struggled for justice alongside labor leaders Cesar Chavez, Dolores Huerta, and Larry Itliong, musicians Abel Sanchez and Jorge Santana's encapsulating tribute song bookends the film, highlighting the ways in which music and the arts were essential in building the farmworkers' movement. 2021
