Why did some Americans boycott grapes in the 1960s?

grape growers were unfair to workers, and the shoppers wanted to help the grapes workers' union

to force growers to negotiate with workers

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
