Why did some americans boycott grapes in the 1960s apex?

Some Americans boycotted grapes in the 1960s because the grape growers were unfair to workers. They were made to work long hours without breaks and little pay. As a result, Americans refused to buy grapes in order to help the grape workers union agitate for better working terms

To force growers to negotiate with workers -apex-
