> Bookishly, an online shop, chose Wednesdays off to avoid having three days in a row

Completely ruins the point for most workers. You’re not getting any additional consecutive time off compared to before, and you have two “Mondays” every week where you will spend part of your day off thinking about going back to work.

> Becoming a four-day operation can be hard in a five-day world

Your business can remain a 5 day operation with half the employees working M-Th and half working T-F. This keeps you fully staffed three days out of the week.
