Factories roared, but workers roared louder. In this episode, the fight for fair pay, safe conditions, and dignity at work takes center stage. From the Great Railroad Strike of 1877 to the Haymarket Affair and the Pullman Strike, Americans learn the high cost of industrial progress. Labor unions like the Knights of Labor and the American Federation of Labor rise to challenge powerful corporations — often meeting bullets instead of bargaining tables. This episode captures the birth of the labor movement, when "eight hours for work, eight hours for rest, eight hours for what we will" became a rallying cry for justice.
