Norma Rae (1979) on Netflix

Norma Rae is a lively, but dependable, wife and mother in an Alabama mill town. Like her father, her mother and most of her friends, she works at the Henley mill, spinning and weaving cloth as the days go by without much apparent purpose. Her "nothing special" life changes when she and her coworkers meet Reuben, a dedicated, smart-mouthed labor organizer down from New York to teach the Henley crew about solidarity in a place where workers and owners alike think "union" and "trouble" are synonymous.
