A fundamental problem is that supervisors themselves (at least in my (20 year) history of working at WPAFB) are not held accountable - or if they are held accountable, are not held accountable for morale, productivity of individual employees, or etc..  This leads to employees that are scapegoats for management failures - directly in terms of badly defined goals or indirectly in terms of others assigned to the project, training, budget, budget execution, etc.  It should be noted that most of my supervisors, the worst ones without exception - were civilians promoted from a technical position to a supervisory position that were not screened for people skills and were inadequately trained and/or mentored.  This was noted as a problem in a 1966 report and has yet to change in my experience.  While there are a few classes given in the first few months regarding what to do, people skills involve how things are done and how to focus on people's needs and abilities are not picked up and certainly not ingrained in an classroom.  In addition, some of the brighter supervisors that I have had were "evil" enough to pick up the language of how to manage without actually executing - so they sound good in meetings but utterly fail on a day to day basis.  

I am not the only employee to fall afoul of a supervisor that was either malicious or stupid - or maybe elements of both; the effects on the employees who has otherwise done a superb job is rather drastic.
