Very curious given that our current calendar weeks are completely arbitrary. How do you explain such a coincidence? If for historical reasons we today happened to have eight day weeks with six workdays how much work would you deliver every day compared to your baseline of a seven day load? I would guess (1/6)*(8/7). Jokes aside, the fact that you won't deliver more results if working longer most likely reflects problems in the way your work is set. Capitalists who seek longer weeks normally make sure it's not the case in their organizations. The reason why we now mostly enjoy reduced hours is not the increased productivity per year (which is not true in general) but a belief that healthier citizens will put in more years of work while straining the healthcare system less. So an attempt to prioritize long-term interests while knowingly damaging the short-term.
