The Federal Workforce is FAT. Everybody knows that. The only way to trim it is to identify the fat. I, of course, believe that the Executive branch has no real intention of cutting jobs, so I understand this is an exercise in public relations. But here goes:
Create an annonymous survey that all Federal employees would fill out. I think if done anonymously, the Federal workforce would identify excess employees. But the survey would have be worded very carefully.
With such a survey, excess employess could begin to be idenditified. But laying off employees is politically very difficult.
That's a start. You want to save hundreds of billions of dollars? Identify and trim the fat. The private sector does it all of the time. The Federal sector could do it too if it was more deliberate.
