That's exactly what Henry Ford found when he introduced the assembly line in 1914. He found that he had to hire 10x more men than he needed because 90% would quit the line within a few weeks. That's where Ford's 'generous' $5 day came from (twice the prevailing wage). Most found the tedium of the assembly line to be insufferable.
I worked in several furniture factories as a youngster, and I share that sentiment. Assembly lines are soul killing.
