Explanation:
The labor movement in the United States grew out of the need to protect the common interest of workers. For those in the industrial sector, organized labor unions fought for better wages, reasonable hours and safer working conditions. The labor movement led efforts to stop child labor, give health benefits and provide aid to workers who were injured or retired.

The earliest recorded strike occurred in 1768 when New York journeymen tailors protested a wage reduction. The formation of the Federal Society of Journeymen Cordwainers (shoemakers) in Philadelphia in 1794 marks the beginning of sustained trade union organization among American workers.
