Someone should try that - instead of offices, give people small, offices/bachelor apartments with small kitchens, bathrooms, and sleeping quarters.
Have them work for 4 days where they are totally tuned in and productive with their team, and then give them 3 days off, where they can go home to their family and completely forget about work.
Sort of like the oil rig model, but for tech workers.
Wouldn't have to live in high COL areas, and have only one commute per week.
This is probably a horrible idea, but then again, the standard workweek that most in office workers adhere to right now isn't super stellar or efficient either...
