If you ask Sweden or Norway, they will probably say yes.
But many argue that this can't work for senior people or the professional services sector, where clients are dependent on being able to contact their law firm or accounting firm at all hours.
It is definitely an interesting debate...
So actually, the reason we work 8 hours a day isn’t based on science, it’s based on history, and therefore arguably irrelevant in todays creative economy. If you were to take into account the science of productivity, it has been shown that generally people can only work at a high performance levels for 90 to 120 minutes before a recharging session of 20 to 30 minutes is needed in order to once again work at a high performance level for another 90 to 120 minutes. Therefore, really, instead of thinking “what can I get done in an 8 hour day?” You should really be thinking, “what can I get done in the next 90 minutes.”
