There was once a young man who worked for me on the Big E. He was a typical nub, qualifying mostly on time, and being where he was supposed to be on time, doing what was asked of him. After I left the ship, he continued to grow in experience, until at his 3 year point on board, he was an old hand, and one of those who were sought out for answers and to get things done.
Towards the end of a particular ship yard period, when NRRO was constantly present, and delays were more painful than at other times, a precritical check-off had to be performed. For whatever reason, the ship had recently had issues with pre-crits, where various administrative errors were committed in their performance, and the Command was not happy. So, the Reactor Officer personally briefed our young hero and another likeminded young sailor, that the pre-crit must be done right, and must be done correctly. They began.
As soon as they were finished witht the last step, but before they or the reactor technician could review their paperwork, the pre-crit was taken for review by higher authority, and a mistake was found. Now, while we all know that human performance tools are critical in the civilian (sorry, commercial) world, and that humans do make mistakes... The Navy in many instances dosen't acknowledge this fact. Mistakes are simply not tolerated. (This may be understandable, given that it is indeed a vessel of war which is trying to return to the fight)
Anyway, the two young men were sent to Captains Mast, and though their LPO, CPO, DO, and RCA went to bat for them, the RO demanded an example be set. One of the young men has re-enlisted, and was under orders to prototype. He lost those orders. The other young man hadn't re-enlisted, and his time left in the Navy was bitter.
Moral: It is true that there are those in the Navy who whine, and didn't do their job from day one. These are to be avoided. But sometimes bad things happen to good people, and they simply want to leave the nest of Navy Nuclear Power for greener pastures.
