Currently not hiring (will hire in the coming months again), but I run a small UI/UX design agency where we help B2B software teams design cleaner & more user friendly products [1].
A 4-day workweek is a core part of our culture. It dramatically increased productivity, increased energy levels and reduced overall mental pressure. The way we make it work is to not have everyone be away during the same day.
It’s really surprising that not more companies have 4-day work weeks.
If you’re an employer and you read this, just give it a try. All your concerns are most likely just limiting beliefs.
