The California agricultural strikes of 1933 were a series of strikes by agricultural workers in the U.S. state of California in 1933. More than 47,500 workers were involved in the wave of approximately 30 strikes. Twenty-four of the strikes, involving 37,500 union members, were led by the Cannery and Agricultural Workers' Industrial Union (CAWIU).
The strikes are grouped together because most of them were organized by the CAWIU. Strike actions began in August among cherry, grape, peach, pear, sugar beet, and tomato workers, and culminated in a number of strikes against cotton growers in the San Joaquin Valley in October. The cotton strikes involved the largest number of workers. Sources vary as to numbers involved in the cotton strikes, with some sources claiming 18,000 workers and others just 12,000 workers. Striking workers were evicted from company housing, and growers and many of their managerial staff were deputized by local law enforcement. Attacks by employers on peaceful striking workers were common. In one attack in the town of Pixley, California, two workers were killed and eight others wounded. CAWIU organizers Pat Chambers and Caroline Decker were arrested and charged under the California Criminal Syndicalism Act for their labor organizing activities.
Cotton growers in the San Joaquin Valley relied on extremely low labor costs to make their crop pay. Although California cotton growers paid marginally better than cotton growers in other states, wages for cotton pickers in California had declined significantly from $1.50 per hundred pounds in 1928 to just 40 cents per hundred pounds in 1932 (although the rate could go as high as 60 cents per hundred pounds for ground being picked over a second or third time). Wages for cotton pickers in the San Joaquin Valley were set by the Agricultural Labor Bureau, an employers' organization.
The Cannery and Agricultural Workers' Industrial Union had been organizing in the cotton fields for some time, and by 1933 had come to provide leadership for the cotton pickers, most of whom were Mexican. The CAWIU was militant in its demands, and threatened a valley-wide strike if they were not met. These demands included a wage rate of $1.00 per hundred pounds of cotton picked, recognition of the CAWIU as the workers' collective bargaining agent, and abolition of "contract labor" (the contracting of a large group of workers for a one-time job or for seasonal labor). These demands were made in practically every cotton strike which followed in 1933.
