Your value is relative not only to your own job but to the job your boss has and to the perception the organization has of both. If you can't directly relate your value to the company's bottom line then you are dependent on your boss doing it for his group and you are just another resource to make that happen. The bigger the organization, the more dependent you become and the more vulnerable you are to being just another red "X" on an org chart when the been counters dictate a cut. If your boss is the red "X" then it's even more important you can describe your real value added to his boss or his replacement. It's not an issue of getting along or being quirky - it's all bottom line in a big organization. If you can't show you are contributing, you are toast at some point.
