What was one direct effect of the assembly line on labor in the early 1900s?

One direct effect of the assembly line on labor in the early 1900s was the significant increase in production efficiency. By breaking down the manufacturing process into simpler, repetitive tasks, workers could produce goods much faster than traditional methods allowed. This led to a rise in factory employment, but also resulted in monotonous work and often lower job satisfaction, as employees performed the same task repeatedly. Additionally, it contributed to the rise of mass production and the availability of more affordable consumer goods.
