While SHORTER (US | UK) moves through production (I get the copyedits next week, and have a bunch of revisions to put in), there’s another book about shortening working hours that’s out: Lasse Rheingans’ Die 5-Stunden-Revolution, or “The 5 hour revolution.”
Lasse moved his company to a 5-hour day a couple years ago, a move that garnered a lot of attention.
It’s not yet out in English, but if you read German, it’s worth checking out. However, if you don’t read German, you can listen to my interview with Lasse, or read about his work when SHORTER comes out in March.
