Have you ever considered the possibility? And if so, which would you opt for? The normal 8 hours a day, 5 days a week to comprise your 40-hour work week with 2 days break inbetween or would you rather work an extra 2 hours each day for a 4 day week with a more balanced 3 day weekend?
With the longer summers we have and mostly good weather I’d opt for the 4 day week. Less travelling into the city, means less congestion and less pollution and would save you money. Or would you make up the difference spending it on your day off?
Wouldn’t people just be more productive with those extra few hours to finish off tasks in the day, and be more refreshed on Monday morning after a 3 day break?
