"UFWOC has undertaken an international boycott of all California-Arizona table grapes in order to gain union recognition for striking farmworkers. We did not take up the burden of the boycott willingly. It is expensive. It is a hardship on the farmworkers’ families who have left the small valley towns to travel across the country to boycott grapes. But, because of the table grapes growers’ refusal to bargain with their workers, the boycott is our major weapon and I might say a nonviolent weapon, and our last line of defense against the growers who use foreign labor to break our strikes. It is only through the pressure of the boycott that UFWOC has won contracts with major California wine grape growers."
