Pros
The pay to work ratio approaches infinity. I did practically nothing 8 hours a day, and periodically there would be a project emergency that would require 12 hours a day 6 days a week of doing nothing. That was at time and a half plus night pay. The health care benefits and retirement matching in the thrift savings plan were exceptional.
Kontras
The endless maze of paperwork, check-sheets and copying and pasting old technical work documents never ended. The training was non-existent, and the routine answer to any question was, "well, I don't know, but we did it like that last time" The building we worked in leaked, and all of the furnishings were provided by the lowest bidder. The toilet paper was transparent, and lacked the minimum tensile strength to even be pulled from the roll. If there were ever a case study to validate the Pareto principle PSNS would be it. I witnessed senior department managers take 2 hour naps after lunch, and a majority of the personnel here were entitled, lazy, and generally worthless. Luckily I took off before receiving my GS-12 or I would have become another statistic for white-collar welfare.
