Since being mandated to work from home, my team has switched to seven hour days (including an hour for lunch, ie, 10:00am - 5:00pm). My dream was a four day work week but this was my second choice! It’s so much easier to stay focused knowing the day is shorter and our productivity has shot up. There are, of course, other factors as well like. It having to commute and working remote, but still, the shorter day makes a huge difference.
