"The GitLab team handbook is the central repository for how we run the company. Printed, it consists of over 2,000 pages of text. As part of our value of being transparent the handbook is open to the world, and we welcome feedback.
Why would you want to read a 2,000 page employee handbook? Because it's amazing. It covers everything from their core values to chat/email etiquette. There's a whole chapter devoted to communications protocols including how to keep virtual workers from feeling ostracized. Another chapter not only reveals the dozens of apps they use to manage their work, but details about how to use them.
