Cannery and Agricultural Workers' Industrial Union

The Cannery and Agricultural Workers Industrial Union (CAWIU) was a Communist-aligned union active in California in the early 1930s. Organizers provided support to workers in California's fields and canning industry. The Cannery and Agricultural Workers Industrial Union (CAWIU) dated back to 1929 with the formation of the Trade Union Unity League (TUUL). With industrialization and the advent of the factories, labor started migrating into the urban space. An influx of immigrant workers contributed to the environment favorable to big business by increasing the supply of unskilled labor lost to the urban factories. The demand for labor spurred the growers to look to seasonal migrant workers as a viable labor source. Corporations began to look at profits and started to marginalize its workers by providing sub-par wages and working conditions to their seasonal workers. The formation of the Cannery and Agricultural Workers Industrial Union addressed and represented the civil rights of the migrant workers. Ultimately the CAWIU lost the battle, overwhelmed by the combined alliance of growers and the Mexican and state governments. The eventual abandonment of the Trade Union Unity League led to the dissolution of the CAWIU, which later emerged as the United Cannery, Agricultural, Packing, and Allied Workers of America (UCAPAWA).
