Following substantial suggestions by @ChuckBaggett, I have significantly revised this post to reflect his input. I want to thank him for his contribution. The improvements here largely reflect his helpful input. Any errors or omissions are my sole responsibility.
I received this very good question on Ask.Fm:
“how do you sell a 4 hour work day to workers?”
My full answer is too long for the Ask.Fm format, so I decided to answer it here. My goal is to provide material in the form of talking points for those who want to agitate for a reduction in hours of labor in their unions, communities and public meetings.
I think the best arguments for reducing hours of labor can be made by focusing on what almost everyone agrees are the most important social ills of capitalism facing us today (even if they do not identify capitalism as the cause): poverty, climate change, inequality, unemployment and stagnation, and the lack of democracy.
Although it might not be obvious to most workers, the number of hours of labor we perform each week have a direct impact on each of these social ills to a degree that seldom understood.
