I doubt they’d think of themselves this way, but my grandmother and mother were quiet soldiers in the war for work equality.
Grandma was hired as a full-time department store clerk during World War II. She was told it was just till the male clerks came home. Management wondered if men would buy underwear from a woman. They did, and Grandma kept her job until she retired years later.
My mother crossed the equal pay for equal work barrier when I was in college.
