Nice piece :) ... to add a category (or a different article altogether!): Justifiable discontent.

This isn't a complaint session :) I do mean this in context with the article.

Small company (ie 30-50). Staff experience chronic discontent, but it is identifiable to HR and Top Management. For years, leadership has lived on unconscious goals not shared with the employees.  Further, have demonstrated inability to foster relationships within the company. etc ...

What I'm suggesting is, discontent is a two way street.  So, when HR and Leadership is/are the source, the pee-ons become the excuse for poor performance.
