She became interested in activism and was a labor activist before graduating from
Brackenridge High School in
San Antonio. Tenayuca's first arrest came at the age of 16, in 1933, when she joined a
picket line of workers in strike against the Finck Cigar Company. After high school, Tenayuca obtained a position as an elevator operator, but she continued working for
human rights. Tenayuca was exposed to many hardships in her community. Often as a young child, she would go to the Plaza del Zacate (Grass Plaza), a public square where
socialists and
anarchists would come to speak and work with families with grievances. Many Mexican and Mexican Americans in San Antonio at the time had fled the
Mexican Revolution during 1910s and were excluded from the New Deal's jobs and housing programs. Additionally, Mexican Americans were facing massive deportations due to fears that they were stealing U.S. jobs and because of reduced jobs available during the
Great Depression.
Labor strike of 1938 San Antonio was a major hub of the pecan industry, partially due to the use of Mexican workers as a cheap source of labor. In 1938, thousands of San Antonio pecan-shellers started a spontaneous strike in protest of poor working conditions, with Tenayuca serving as the strike committee chair. Tenayuca was just 21 years old when the strike occurred in the community. During the strike, up to 12,000 walked off the job in protest of a salary reduction from five cents a day to three cents a day and terrible working conditions. The WAA was established in 1935 by the Communist Party USA (CPUSA) as a front organization to mobilize the unemployed, underemployed, and unskilled workers who were shut out of traditional unions during the Great Depression. The organization's goal was to promote government-funded unemployment insurance, employment aid programs, and the defense of workers' rights. She gained the respect and admiration of her coworkers and the larger labor movement because of her persistence and unflinching dedication to the cause of workers' rights. Tenayuca constantly fought to organize employees and advance the objectives of the organization as a prominent and outspoken WAA member. == Civil rights activism ==
