If the context here is the development of human history leading up to notions of private employment then our timeline is in the tens of thousands of years and variations within past decades become almost irrelevant. Comparing hunter-gatherers or roaming tribes with modern city dwellers? Enough said. I'm not sure I disagree with you about the last 50 years. I think it's a bit of a hard topic to dissect because the notion of a "workday" is relative and changes over time. I think a day of work is a lot easier now than in the 1950s and I think the ancillary work we perform to care for ourselves and our homes is reduced. By how much, I'm not sure how to quantify. I recall Hans Rosling did a great talk along these lines, "The Magic Washing Machine." It's mostly talking about the mechanization of household labor in the mid century which we agree took place. I think since then we no longer spend as much time cooking, or cleaning, maintaining our appliances or cars. I think improvements in communication systems save a surprising amount of time -- consider how many hours a month you might waste if cell phones didn't exist? If you had to drive to a place to sign paperwork instead of fill out an online form? There's nothing so large as the washing machine in the last 50 years but I think we have a significant amount of small improvements. Coupled with work becoming more palatable (part of why work/life becomes blurred is that some large percentage of us enjoy working) I think there's a possibility that labor has shrank in the last 50 years even if people work longer hours. Which they may not, factoring in household labor. I know many people who do not need to work as hard as they do -- some who do not need to work at all. Yet they still do, even when the requirement is removed. My opinion about the last 50 years is fairly weakly held, I'm basically just thinking freely. My strong comments above are in reference to the development of much more basic notions like "private employment."
