I've Licked Blood
A little over a year ago, at the beginning of May 2024, I switched to a 4-day-work-week, signing a side-agreement that I would do so for two years for now. Well, now that I have reached half-time of this "experiment" I already know that I have licked blood and cannot imagine ever going back to working Fridays. I work a minimum of 9 hours now (having elected the 36-hrs-option) Monday to Thursday and officially start an hour earlier than I used to, but having 3-day-weekends EVERY weekend is bliss. You can get so much more done, do spontaneous weekend trips that start on Friday morning and even if you just want to do nothing much and chill at home, there's more time for that. My productivity definitely has not suffered and I can count the occasions on one hand when somebody had wanted to include me in a meeting or event on a Friday, so I definitely picked the right day of the week off. In other workds: wishing colleagues a good weekend on a Thursday afternoon already just "hits different".
