This is actually how culture work began. Factories used to have long days with no vacations, until experimentation proved that having people work less can mean more. Working less meant more long-term work due to fewer injuries and thus lower turnover costs.
Could this be our future?
If you think this is all good news, it’s not as simple as less work. The companies that do it also add more discipline such as no social media or even phones during those highly focused hours.
As usual, don’t believe this or a anything I say! Test it out for yourself and use real-world data.
