The comment below was obviously submitted by an employee who understands the undeniable truth and reality of workplace politics, performance, and bias.

It is an undeniable fact that the U.S. Government does not implement proven management science techniques in the screening and selection of supervisors through sociological and psychological testing to prove their mental fitness to manage the psychological complexity of employees in the workplace.

For that reason alone, and until such time as managers are cognizant of the importance of human emotions relevant to productivity, the pursuit of a fair 
system of managing the federal workforce will remain grossly inadequate.  
 
NSPS designers could potentially save the U.S. Government billions of dollars in greivance claims by taking the advice of a reputable panel of sociologists and 
psychologists in the formation and design of the proposed NSPS system to insure employee protections from workplace bias and prejudice by supervisors.
 
Workplace bias is the single key to making this new personnel system successful and making it equitably fair and just for all employees under it's control.

The proof of these facts were recently confirmed by the growing suicide rate among both civilian and military employees throughout the Air Force.  

Comment:  "I  believe that any supervisor can withhold pay increases if they are not fond of the person who feels they deserve to have one. Those folks who are the “favorites” will be the ones to go forward."
