This is a link to Valve's employee handbook from 2012, available to read in full online; read the "Your first day" section if nothing else:

Two books that look at the evolution of purpose-driven, liberated workplaces are:

• Reinventing Organizations: A Guide to Creating Organizations Inspired by the Next Stage of Human Consciousness, Frederic Laloux
• Freedom, Inc.: Free Your Employees and Let Them Lead Your Business to Higher Productivity, Profits, and Growth, by Brian M. Carney and Isaac Getz 

While there is no way to transplant the mindset, there are frameworks that may help with this shift in thinking. Sociocracy and Holacracy are two similar ideas:

• We the People: Consenting to a Deeper Democracy, by John Buck and Sharon Villines
• Holacracy: The New Management System for a Rapidly Changing World, by Brian J. Robertson

Worldblu is an example of an organization that advocates more democratic workplaces: https://www.worldblu.com/.
