Factory Girl by Barbara Greenwood
At the dingy, overcrowded Acme Garment Factory, Emily Watson stands for eleven hours a day clipping threads from blouses. Every time the boss passes, he shouts at her to snip faster. But if Emily snips too fast, she could ruin the garment and be docked pay. If she works too slowly, she will be fired. She desperately needs this job. Without the four dollars a week it brings, her family will starve. When a reporter arrives, determined to expose the terrible conditions in the factory, Emily finds herself caught between the desperate immigrant girls with whom she works and the hope of change. Then tragedy strikes, and Emily must decide where her loyalties lie.
