Cesar Chavez, the famed civil rights and labor leader who co-founded the National Farm Workers Association (now called United Farm Workers), is being honored this week all across the country. Schools and public offices in several states were closed today in recognition of Chavez and his activism for laborers everywhere.

There is also an annual Cesar Chavez March For Justice in San Antonio, which takes place on Saturday and will, for the first time, begin on a street named after the activist.

The name change caused quite a stir when the San Antonio Conservation Society sued the city over it, claiming it infringed on their mission to preserve certain historic elements of the city.

Chavez’s son, Paul F. Chavez, will act as grand marshall in the march; he’s currently president of the Cesar Chavez Foundation, which provides affordable housing in the Southwest. When asked what his father’s legacy means to him, he replied, “That the lessons learned in the rural parts of the country apply to people of all walks of life. He went and rallied and got people to believe they were important, that the poorest among us could take on and beat the most powerful industry in California. My father’s work transcends the farm workers’ movement.”

People are encouraged to celebrate his day by volunteering and learning about his work.
