Shel Holtz has started a wiki called “The Employee Communications Manifesto”:
Internal communications seems to be performing less than brilliantly at achieving its goals of employee alignment and line of sight. One reason (and this is purely speculation on my part) is the lack of a common knowledge base for anyone starting out in an employee communications job. […] It’s my hope that The Employee Communications Manifesto can help fix that. It’ll work if internal communications professionals engage the wiki and create its contents. I hope to see you there.
