I'd rather work full 8 hours a day but have 4-day workweek. Ideally I'd prefer Wednesdays to be non-working days - this way I wouldn't have to spend more than 2 days in a row working in the office. For me this would feel even better than just 3-day weekends with 4-day contiguous workweeks. 5-vs-2 feels like you live in the office and go to visit home. 4-vs-3 feels the same although notably better. 2-1-2-2 (office-home-office-home) would actually feel you live at home and go to the office to get the job done. I even feel almost sure this would boost my actual office-time productivity.
