This image, taken by photographer Paul Sequeira in Chicago, shows union workers urging the boycott of lettuce, grapes, and wine grown in California by growers who signed contracts with the Teamsters. The United Farm Workers (UFW) organized strikes and boycotts following the earlier “Salad Bowl Strike” to protest the Teamsters’ refusal to recognize the UFW’s right to organize field workers.
This photograph was taken as part of the Documerica project – a social and environmental photography project sponsored by the Environmental Protection Agency during the 1970s.
