A 4 day work week is a great step in the right direction. These things can be figured out on a case by case basis--many businesses are already running on sub 5 day work weeks, or their work weeks are abnormal (Tues-Sun, Wed-Sat, etc.). But, yes, there will need to be some businesses who retain the 5 day work weeks. However, the benefit is that a large percentage of workers will have an extra day per week to focus on family, hobbies, engaging in the local economy. That outweighs any of the concerns you bring up.
