The title you lose may reveal which people were addressing the role all along.

Losing a role sorts your contacts quickly. Some people go quiet, and their absence is a real loss even when it is not personal, because they were dealing with the position rather than with you. Others carry on exactly as before, and that continuity is worth more than almost anything a title provides. The information is painful and unusually clear, and none of it was available while you still held the job.

Notice who calls in the first month after any change of standing. Then be that person for somebody else who has just stepped down or been let go.
