Frankly the government should relocate to the suburbs and abandon the downtowns to the federal courts.
So why are they getting bonuses?
With the exception of the Air Traffic Controllers I cant imagine it is for performance.
I at least have not heard of any Government entities coming in under budget in my life time.
I think it would have made the news.
With 10%+ unemployment in the USA, I doubt retention of cushy civil service/union jobs would be much of a problem these days!
