I’m currently hybrid: 2 days at home, 3 days in office but no one’s really counting. I realize I’m not quite the target of the question, but even I can the difference.
It’s very easy to never leave my home on WFH days and that absolutely has a negative effect. It makes the days going back to the office feel more refreshing, like I have more oxygen. That said, there are of course plenty of upsides to WFH.
I’m not sure what a software solution would like. Maybe reminders to get out of the house, or something that tracks how long it’s been since I’ve seen a friend in person.
