left to rot on the docks. This event sparked the decision to use the protest tactic of boycotting as the means by which the labor movement would win the struggle against the Delano grape growers. This initial successful boycott was followed by a series of picket lines on Bay Area docks. The International Longshoremen's and Warehousemen's Union, whose members were responsible for loading the shipments, cooperated with the protesters and refused to load non-union grapes. Chavez's successful boycotting campaigns in the docks inspired him to launch a formal boycott against the two largest corporations which were involved in the Delano grape industry, Schenley Industries and the DiGiorgio Corporation. Starting in December 1965, Chavez's organization participated in several consumer boycotts against the Schenley corporation. The increased pressure from supporters in the business sector led to the farm workers’ victory and acquisition of union contracts that immediately raised wages and established hiring halls in Delano, Coachella, and Lamont. The large corporations affected by the strikes led by Chavez employed fear tactics in order to protect profits. The documentary The Wrath of Grapes'' mentions that the Delano-based company, M Caratan Inc., hired criminals to break up farm workers voting to unionize. They attacked voters, overturned tables and even smashed ballot boxes. The DiGiorgio Corporation was finally pressured into holding an election among its workers allowing them to choose the union they wanted to represent them on August 30, 1967. This came as a result of the boycott tactic of blocking grape distribution centers. With their products not on the shelves of retailers as a result of the boycott, the DiGiorgio Corporation was pressured to answer to the demands of the farm workers. The result of the vote favored the union representation of the UFW, a 530 to 332 vote, against the representation of The Teamsters, which was the only union that was competing against the UFW in the election. On July 29, 1970, the grape strike and boycott ended, when grape growers signed labor contracts with the union. The contracts included timed pay increase, health, and other benefits. Geography The grape strike officially began in Delano in September 1965. In December, union representatives traveled from California to New York, Washington, D.C., Pittsburgh, Detroit, and other large cities to encourage a boycott of grapes grown at ranches without UFW contracts. In the summer of 1966, unions and religious groups from Seattle and Portland endorsed
