9 to 5 wasn’t just a comic film—it was a movement built by Ellen Cassedy and her friends.

Ten office workers in Boston started out sitting in a circle and sharing the problems they encountered on the job. In a few short years, they had built a nationwide movement that united people of diverse races, classes, and ages.

They took on the corporate titans. They leafleted and filed lawsuits and started a woman-led union. They won millions of dollars in back pay and helped make sexual harassment and pregnancy discrimination illegal.

The women office workers who rose up to win rights and respect on the job transformed workplaces throughout America. And along the way came Dolly Parton’s toe-tapping song and a hit movie inspired by their work.

Working 9 to 5 is a lively, informative, firsthand account packed with practical organizing lore that will embolden anyone striving for fair treatment.
