&gt; The question is not whether or not you&#x27;re as productive, but rather, are you more than 80% as productive as you were before.<p>Absolutely, that was what I was trying to convey (productivity per hour rather than total productivity) but it was poorly worded. A lot of discussion around shortening the work week focuses on the latter. While there may be cases where that&#x27;s true, I think focusing the discussion on that is wrong because it assumes that there has to be an economic argument for making the change. For me, people having more free time is a positive in itself that society should probably optimise more for.<p>I am certainly not less productive per hour worked. I might be more productive, I don&#x27;t know, but that should not be the only reason we contemplate such a change.
