Pros
Civil Service employees have the ability to carry health care plan into retirement, very small pension however. Great job satisfaction as I work to assist those who are separating/retiring from the military in entering the private sector workforce. Given the authority and tools needed to develop an excellent program, minimal micromanagement. Until recent federal funding cutbacks there was excellent opportunity for professional development and training. This may return as the economy recovers and funding improves.
Cons
All federal systems have extensive instructions, requirements and restrictions that you have to work within. Promotion opportunity is extremely limited and frequently requires moving when a position is opened by retirement or departure of incumbent.
