Pros
For someone looking to just warm a chair, do the bare minimum, and go home at 4, this is a perfect place to be. When starting, you get some decent training, depending on your career field, then either get tired of not enough work or watch YouTube/facebook all day.
Cons
This is not the place for innovators or those with a drive to achieve something every day. If you go overseas, there is always a manning shortage and a lot of work needing to be done, resulting in fulfilling work, but the stateside is a waste of taxpayer money. Civilians who have been in place for decades, more often than not, prefer nothing to do so they can be retired in a cush office outside their home. Some are great, but most are leeches on the government welfare system, the DoD.
