I loved "Reinventing Organizations" as well. It's interesting because some of the Teal ways of doing things rubbed me the wrong way because they felt too "touchy-feely" and I thought that my coworker would never go for this. I tried to have enough self-awareness to realize that maybe that's how people stuck in the Orange way of doing things feel about Green practices. Like you, I would love to hear from people who are working in a Teal environment.
If you're interested in other books that talk about the future of work I would recommend Creativity, Inc by Ed Catmull (about how Pixar works) and Work Rules! by Laszlo Bock (about how Google HR works). They're both fascinating insights into how two modern companies try to do their best work.
Would love some recommendations if you have any as well.
