mind your business: Indispensable, Irreplaceable You

Unfortunately, few people describe themselves as irreplaceable. When a new boss comes onboard, or an existing employee is promoted to a managerial position, often their first step is to actively seek out people with ideas about "making things better around the office." These individuals can be called the "linchpins," and they are the ones who have lived and will continue to live in the organization long after the incoming boss is gone. They have more skin in the game—and perspective-so seeking them out will aid the manager in assessing the organization's capacity—its ability to grow.
