César Chavez and Dolores Huerta are once again drawing wide attention as allegations have emerged involving Chavez and women and girls connected to Huerta, according to reporting by The Associated Press. In that coverage, organizers of Chavez celebrations planned around the country said some events have been canceled in response to the allegations, which Chavez’s family and supporters have faced as part of a new round of scrutiny of the labor movement’s public legacy.

The AP report said both Chavez and Huerta are credited with leading a campaign that pressured growers to negotiate for improved pay and working conditions for farmworkers. It also said the movement’s rise is seen as central to both U.S. history and U.S. Latino history by labor historians, even as the new allegations have changed how some communities are handling commemorations tied to Chavez.

Paul Ortiz, a Cornell University labor history professor, told the AP that the United Farm Workers made “the most important sustained changes” to agricultural workers’ conditions in the nation’s history. Ortiz said organizers worked to build momentum among agricultural workers across states—describing efforts that, he said, had often failed in the past and sometimes “catastrophically”—before the movement gained enough leverage to win negotiations with growers.

Ortiz also pointed to the historical pattern of farmworkers trying to organize for better wages and conditions, describing such efforts as stretching “from Hawaii to Florida to New York to Southern California” across centuries, including periods going back to slavery. In the AP account, Ortiz’s focus on persistence underscores how Chavez and Huerta are commonly credited with transforming organizing from repeated, often unsuccessful attempts into negotiated labor contracts and broader labor protections.

Chavez is described in the AP report as known for early organizing in the fields, a hunger strike, and a grape boycott that helped lead to growers negotiating with farmworkers. The report said Chavez was born in Yuma, Arizona, and grew up in a Mexican American family that traveled around California picking crops such as lettuce, grapes, and cotton.

The AP coverage said California farmworkers faced harsh conditions and low pay, and it described the movement’s push for change through concrete workplace reforms. It cited a National Park Service document supporting a national monument in Chavez’s honor, saying the farmworker movement lifted wages, banned short-handled hoes, and established state-mandated clean drinking water and restrooms in the fields.

The AP report also described organizing milestones tied to the movement. It said Chavez led a march that started in Delano, California, and ended in Sacramento with 10,000 people, according to a proclamation by former President Barack Obama in 2014. It also said a boycott of grapes drew participation from about 17 million people, according to that same proclamation, and that growers accepted some of the first farmworker contracts in history.

Huerta’s biography in the AP report highlights her role in organizing and negotiations as well as her work with wider civil rights causes. The report said Huerta helped organize the 1965 Delano strike of 5,000 grape workers and was the lead negotiator in the contract that followed, citing the National Women’s History Museum.

In the AP account, Huerta is described as a single mother who gave up a stable teaching career to organize, and it said she was jailed over 20 times for protests. The report also said she was seriously injured in 1988 while demonstrating, later championed women’s rights, encouraged Latinas to run for office, and founded the Dolores Huerta Foundation to combat discrimination, poverty and inequality.

The AP report said Huerta coined the slogan “Sí, se puede” in 1972 during her work rallying Arizona farmworkers against a law banning boycotts and strikes, and it said she received the Presidential Medal of Freedom in 2012. It also said in 1993 Huerta became the first Latina inducted into the National Women’s Hall of Fame.

The AP report concluded that even as celebrations tied to Chavez are being reevaluated in light of the allegations, both Chavez and Huerta remain central figures in how many accounts describe the shift farmworker organizing achieved in wages and working conditions. The report also said Chavez and Huerta’s efforts are credited with helping spur California to pass its first state law recognizing farmworkers’ right to collective bargaining.

The AP report said Chavez and Huerta have had streets and schools named after them, and it noted that March 31—Chavez’s birthday—has been designated as a day of commemoration in several states, including when Obama declared it a federal commemorative holiday in 2014. For many organizers and officials, the labor legacies associated with Chavez and Huerta remain part of public memory even as communities respond to new claims about Chavez’s conduct.
