Obreros Unidos

Obreros Unidos (1966–1971) was an independent agricultural labor union founded in Wisconsin in 1966 by Mexican American civil rights activists Jesus Salas, Francisco Rodriguez and many more, originally Texas-based farm workers from the small town of Crystal City. The union took root after a march from Wautoma, Wisconsin, to Madison, Wisconsin that state's capitol to protest the working conditions of the thousands of annual Mexican-American migrant workers who traveled from Texas to Wisconsin each year. This protest march was inspired by the similar march of César Chávez' United Farm Workers (UFW) in California earlier that spring, and the Texas Farmworker march on Austin, Texas of 1966. Obreros Unidos engaged in its first labor action by seeking to organize migrant potato harvest and processing workers in the town of Almond, WI, and received support from the AFL-CIO, Cesar Chavez, and other labor unions.

The name means "united workers" in Spanish.
