lacajun,
To say that CYA is a part of life is possibly true, but to me, only acceptable to a point. It depends on the context. If by "CYA" it means making sure that your nose is clean and that you always have enough evidence (memos, emails and such) that, if poop ever hit the fan you could hold it up to people and say, "See? It wasn't my fault. My backside is covered.", then I have to say that I *hate* CYA mentality and I refuse to be in that mode. On the other hand, if by "CYA" it means just making sure that the work you do reflects an honest, good effort so that you can point to it and say, "See? I am proud of this work.", then I am all for CYA.
But, I never was especially politically astute, and relative to my age, I have (through my own conscious doing) done a profoundly good job of climbing *down* the corporate ladder. Others my age are now VPs, managers ... MBAs ... driving around in BMWs, Mercedes, living in 4000 square foot homes in the winter and private condos in Mexico on their vacation. Me, I am still just an engineer who lives in a small house on a hobby farm with a couple of horses and a plethora of dogs, driving a pick-up truck.
Sometimes I think I should have done more CYA and less of whatever it is I have spent my life doing. Some days I feel like I have become nothing more than a mere soap tablet in the urinal of engineering.
Those are the days I drink beer and think, it might not be covered, but other people can nonetheless kiss it.
In the end, the only thing of much value is character, and my opinion is that people who are predisposed to a classic "CYA" (meant in the negative sense) mentality tend to have less of it.
