Looking Back: Changes for America in 1914
Discusses the labor movement of the 1910s. Topics includes:
- The treatment of immigrant workers in factories, who were very grateful to find jobs in America.
- Why many factory workers resorted to striking, including the fact that they were hoping to get their jobs back after the strike was over.
- The mistreatment of teenage girls and women in factories, which lead many of them, including Bessie Abramowitz, to fight for newer changes.
- How Clara Lemlich's 1909-1910 strike, which involved 10,000 women and girls, managed to earn them higher wages and shorter hours.
- How the Triangle Shirtwaist Factory Fire of 1911 helped in improving working conditions for factory workers, and how long it would take until all Americans have today's labor standard.
- Changes for Rebecca is the second Historical Character book that addresses labor issues in the early 20th century, after Samantha Learns a Lesson.
