 Union members picketed the cannery, grocery stores that sold Cal San goods, and the houses of the Shapiro brothers, the plant's owners.Faced with children holding signs bearing slogans such as "I'm underfed because Mama is underpaid," the Shapiro brothers met with negotiators and soon reached a settlement.The Cal San local became UCAPAWA's second largest, and the union's ranks grew to include the workers at several California canneries.
