César Chávez Day is celebrated on March 31 each year in honor of the life and legacy of César Chávez, an American labor leader and civil rights activist. He co-founded the United Farm Workers (UFW) and worked tirelessly to improve conditions for farmworkers, advocating for better wages and labor rights. The day serves to recognize his contributions to social justice and labor rights. In many states, César Chávez Day is observed as a state holiday or a day of service. Schools and communities often hold events to educate people about Chávez's work and the importance of advocating for workers' rights. It is a time to reflect on the ongoing struggles for equality and justice in the workplace.
