      Pros

      Worked with a lot of wonderful people at Y-12. Great work-life balance and relatively flexible hours.

      Cons

      Dealing with security nuances is something that takes time to get used to. Some employees have a negative attitude.

      Good work schedule 4 days on 3 days off, big safety culture. Seems to emphasize on retention. Lots of cool projects and opportunities to learn.

      Projects a bit slow sometimes, ongoing major construction.

      Pros

      - Four 10-hour workdays weekly, plus time balancing - Very strong job security - Work-life balance is very good - Work culture is good, the people are very down-to-earth and relaxed - The work supports an important, meaningful mission

      Cons

      - DoE work pacing is very slow at times - Opaque promotion system that seemingly rewards less experienced new hires much more than long-term employees, with respect to time in grade
