Pros
Employees are able to see technological marvels, vehicles sent to space, and rocket launches! It gives a great sense of making a difference for the greater good of mankind. The pay, benefits, hours are great. People are pleasant and stress is kept to controllable levels. There is a great opportunity to diversify and learn from others.
Cons
3 Major Complaints Only: 1) Too many Chiefs and not enough Indians (which means you have a chance to make more money, but there should be less management layers and more workers!) 2) NASA has become too risk adverse through the years. They should be willing to take a little extra risk when the rewards could pay off drastically. This manifests itself in veteran employees often stunting the younger and/or more adventurous employees from trying new things and breaking the mold of how things have always been done. 3) As with probably every government job, things move at a glacial pace sometimes. There are a lot of workers that take advantage of their job security and weigh things down.
