Drucker's Lost Art of Management [1] contains some amazing foundational material (as opposed to quick-fix 'techniques' you get in other leadership books) on how to build an effective organizational culture. It shows that for Drucker, the modern corporation is an integral part of civilizational fabric (just like family and other social institutions), and that it too should be governed by moral values and that those values are the glue that holds it together as a community.
