This study is a perfect fit the HN crowd who won't question the methodology and incentive systems because it fits their narrative. Of course employee are going to report happy. What next? a study saying "Employees love more money for the same work?"
Just curios, why single-out HN crowd though???. In a typical 'HN crowd' comment, it is usually about a persona that think 'tech is great' or 'tech can solve all problems', not this particular characterization of 'worker vs management'.
Some examples:
* Never-ending optimism about UBI, despite the maths clearly not working. Kind of similar to this really.
* Expecting salary to exactly match value - i.e. to get the same pay remote working no matter where you live. The number of people here that fundamentally don't understand that salary is a supply/demand negotiation is weird. And they really don't think it through to the obvious conclusion if it did happen - they'd get paid the same as people in Eastern Europe or India.
I think a 4-day work week could eventually happen, but HN types like to pretend it will make people more productive which it absolutely won't. It probably won't reduce productivity to 80%. More like 90%. But it will happen as a cultural shift; not because it increases productivity.
