The first Delano grape strike was organized by the Agricultural Workers Organizing Committee and the United Farm Workers against grape growers in California. The strike lasted from 1965 to 1970, when the UFW was able to reach a collective bargaining agreement with the grape growers that affected nearly 10,000 workers.
In 1973, the boycott began again after UFW lost many of its labor agreements to the Teamsters Union. The second grape boycott overlapped with the union's call for consumers to shun two other nonunion products--lettuce and Gallo wines. The rally cry was "No Grapes" or, in Spanish, "No Uvas". Union officials said that as many as 17 million Americans were avoiding buying grapes during the boycott. The second grape strike ended in 1977 after the passage of a California farm labor law that was considered the strongest in the nation.
