It happens all the time. Headquarters or owners drops someone in to help a division or portfolio company accelerate through a point of inflection, working for a boss who doesn’t want them. If you’re the one getting dropped in, emphasize building trust in the face of possible distrust or resentment. Jump-shift your loyalties immediately. 1) Disengage from your previous situation; 2) Engage with your new boss; and 3) Do what is required to accelerate progress – in that order.
