I work for Treehouse. The 4-day work week is amazing and I feel it'd be very hard to go back to 5 days a week. What do I do on my Fridays? If I have errands, they get run. I usually pop-in and off my computer. Sometimes I actually am working, but I'm "playing". I'm a data scientist and I love my job. I love working on my tools and I love trying new methods. So I might be improving my D3.js skills. Or learning Python (like I have been). Or teaching myself new Bayesian analysis, or survival analysis methods. So in once sense I work on Fridays, in the other hand it feels like play. And I'm not obligated, so I can get up whenever. Also, this isn't every Friday or weekend. Many weekends are just non-tech play, like a trip to Boston. In general, my stress level is way down. I feel focused and happy to be at work when I'm "there" (I work remotely, another Treehouse core value). I think about Treehouse, much more than 4 8-hour days a week, but it's so much more pleasurable! I'm totally thankful to work for Treehouse.
