Here are the key points from the documentary:
1. Mill owners in Massachusetts resisted the new rules about a shorter work week and lower wages. They threatened to fire any workers who joined unions or went on strike.
2. The labor strike was an appropriate response by the unions. The mill workers, including children, were being overworked and underpaid in dangerous conditions. A strike was really the only way for them to advocate for safer working conditions and fair treatment. It helped draw attention to their poor treatment and push for labor reforms to improve their lives and working conditions.
