Summary of this topic:
The short list is an abstract term which describes a "mental list" which senior managers unconsciously keep in their head. It is a list of people, usually, who are their organization. There are two categories for the list, one in which the manager really likes the people and other, where they really dislike the people. If you are in the like category, there is little you can do to fail in their eyes. If you are on the dislike side, there is little you can do to redeem yourself no matter how well you do in the company.
Sales Advice: If you are the type that abuses power in an organization, it will eventually catch up with you. Most people who abuse their power are short sighted and depend on someone above them to protect them. As soon as the person above them is gone, and eventually they will be, they no longer have the power they once had. People will be gunning for them and if you counted on them to back you up, the same people will be gunning for you.
