As a former Nuclear Ops Engineer I used to rotate 12 hour shifts on a weekly basis.. Days, mids, and grave all in one month. We were paid very well, but I would get at least a head cold every week. I soon realized that nuclear operation is not worth my health. I quit my job and entered the IT / Start up world making much less… Even though I work more hours than before, the rotating schedule is gone and being sick is now a rare occurrence! The move was one of the best decisions I ever made and I love this article because it confirmed that decision I made so many years ago.
