This article explores the process and meaning of occupational mobility among a selected sample of 40 immigrant and nonimmigrant women of Mexican descent in the San Francisco Bay Area who entered the secondary labor market of semiskilled clerical, service, and operative jobs in 1978-1979 and 1980-1981. This labor market was segmented along race and gender lines with few promotional ladders available as the work force became more nonwhite and female. When Chicanas and Mexicanas obtained jobs with fewer Chicano coworkers and (...) greater avenues for advancement, they reported escalating conflictual social relations at work. Occupational mobility contained both objective and subjective dimensions for the respondents. Often a woman felt mobile in a job that lacked the means for advancement because she compared herself to a local Chicano or Mexicano working-class reference group and a self-concept rooted in her class, race, and gender.
