César Chávez Day is March 31. In eight states, it's a recognized holiday. Most Americans couldn't tell you what he actually did.
Who Was César Chávez and Why Is There a Holiday Named After Him?
César Estrada Chávez (1927–1993) was a Mexican-American labor leader and civil rights activist who co-founded the United Farm Workers union. He organized strikes, boycotts, and marches that transformed working conditions for farmworkers across the United States. Eight states recognize March 31 as César Chávez Day.
This is that story.
Who He Was
César Estrada Chávez was born on March 31, 1927, in Yuma, Arizona. His family were farmers — they owned a small farm and a store, then lost both during the Depression. Like tens of thousands of other Mexican-American and Mexican families in the 1930s, the Chávez family became migrant farmworkers, following harvests across Arizona and California.
Chávez grew up picking crops. He attended more than 30 schools as a child, following the seasons. He dropped out at 8th grade to work in the fields full-time after his father was injured. He served in the Navy. He came back to California and went back to farm labor.
He knew the system he was going to fight from the inside.
The System He Was Fighting
California agriculture in the mid-20th century ran on one of the most exploitative labor systems in the United States. Farmworkers — predominantly Mexican, Mexican-American, and Filipino workers — had been specifically excluded from the labor protections that most American workers had won through decades of organizing.
The National Labor Relations Act of 1935, which guaranteed most workers the right to organize unions and bargain collectively, explicitly excluded agricultural workers. This was not an accident. It was a deliberate exclusion lobbied for by Southern Democrats who wanted to protect agricultural labor systems (and by extension racial hierarchies) in their states — and the exclusion stuck when the law applied nationally.
Farmworkers could be fired for any reason. They had no right to overtime pay. No right to bathroom breaks. No right to water breaks in fields that reached 100°F and above. No right to collective bargaining. No protection from pesticide exposure.
Contractors who recruited workers often charged for transportation to job sites, for housing in labor camps, for food — deducting the charges from wages before workers ever saw payment. Workers who organized or complained could be blacklisted from the entire regional labor market.
This was the system Chávez was going to challenge with a grape boycott.
Building the UFW — With Dolores Huerta
In 1962, Chávez co-founded what would become the United Farm Workers of America (UFW) with Dolores Huerta — a labor organizer and activist who is as central to the UFW's founding and strategy as Chávez and who has, historically, received less credit for it.
Huerta brought strategic and political sophistication to the organization. Chávez brought the organizing model he'd learned working with the Community Service Organization (CSO) — a grassroots organizing network that Fred Ross had built in Mexican-American communities — and the moral framing that would define the movement.
The UFW's motto — ¡Si Se Puede! (Yes We Can!) — came from Dolores Huerta. It was coined during a 1972 fast Chávez undertook in Arizona and has since become one of the most widely used organizing phrases in American political history.
The Delano Grape Strike
In September 1965, Filipino farmworkers in Delano, California — led by the Agricultural Workers Organizing Committee — went on strike against grape growers, demanding wages that met federal minimum wage standards. They asked the UFW to join. Chávez and the UFW voted to join the strike.
The Delano Grape Strike lasted five years.
Chávez understood early that the strike alone wasn't enough. Growers could replace striking workers. The real leverage was the consumer boycott. If Americans stopped buying California table grapes — if the market for the product disappeared — the growers would have no choice but to negotiate.
The UFW organized a national boycott of California table grapes. Chávez and union organizers traveled the country, speaking to labor unions, churches, student groups, civil rights organizations. Robert F. Kennedy visited the strikers in Delano and publicly supported the boycott. Consumer awareness spread.
By 1970, growers signed contracts with the UFW. For the first time, California farmworkers had collective bargaining agreements.
The Fasts
Chávez undertook three major public fasts during his organizing career — in 1968, 1972, and 1988.
The fasts were acts of nonviolent protest in the tradition of Gandhi, whom Chávez had studied. They were also responses to specific moments: in 1968, a faction within the UFW had begun discussing violence as a tactic, and Chávez fasted to recommit the movement to nonviolence. In 1988, at age 61, he fasted for 36 days to protest the use of pesticides on California grapes and the resulting illness in farmworker families.
The fasts had political effect. They drew national media attention. Robert F. Kennedy's presence at the end of the 1968 fast — breaking bread with Chávez in front of thousands of farmworkers — became one of the defining images of that political moment, weeks before Kennedy's assassination.
The 1988 fast damaged Chávez's health in ways that may have contributed to his death five years later.
His Death and Legacy
César Chávez died on April 23, 1993, in San Luis, Arizona — near where he was born. He was 66. He died in his sleep during a trip to testify in a legal case involving the UFW.
He was posthumously awarded the Presidential Medal of Freedom by President Clinton in 1994.
His legacy is specific: he helped win labor protections for a group of workers who had been deliberately excluded from those protections. The California Agricultural Labor Relations Act, passed in 1975 — the first state law in the United States guaranteeing farmworkers collective bargaining rights — would not have existed without the UFW's organizing.
More broadly, his movement demonstrated that Mexican-American organizing, connected to the broader labor movement and the civil rights movement, could win. In the landscape of 1960s America, that demonstration mattered.
Why His Image Is Everywhere
César Chávez appears in murals across California, Texas, Arizona, and anywhere with a large Mexican-American population. His face — specifically his face from the UFW protest photos of the 1960s and 70s, lean and serious and unmistakably determined — has become one of the most recognizable images in Chicano visual culture.
He appears alongside Emiliano Zapata, alongside MLK, alongside Dolores Huerta, alongside the UFW eagle (a stylized Aztec eagle in black on a red background, designed by Chávez's cousin Manuel Chávez in 1962).
He's on shirts because he's a hero — one of the few widely recognized heroes of Mexican-American political history. In a culture that has often been invisible in the official American historical narrative, having someone whose face is known and whose work is documented matters.
The image also carries a political meaning that's specific to the present: farmworkers are still working under conditions that are better than 1965 but far from equal. Immigration enforcement and labor rights remain in tension. The organizing Chávez started hasn't finished.
Why It Still Matters
The UFW's exclusion from the NLRA was partially addressed in California but never federally. Farmworkers at the federal level still have fewer protections than most other categories of workers. The supply chains that bring agricultural products to American tables still depend heavily on underpaid labor.
When someone wears a César Chávez shirt or hangs his image, they're often not just honoring a historical figure. They're making a statement about where those conditions stand today.
Sí se puede — yes it can be done — is a present tense statement. It was when Dolores Huerta said it in 1972. It still is.
