You were promoted on a Tuesday. On Wednesday you manage the people you ate lunch with. Nobody scheduled you a training course, and nobody took your old work away.

This is a handling of that specific situation: the internal promotion, the first ninety days, the people who used to be your peers. It moves in order, from the conversation where you accept the job to the calibration meeting where you defend your first ratings.

Inside: how to hand over your old workload before it eats your calendar, what to ask in the first 1:1 with each person, what to say to the colleague who applied for your role, how to renegotiate a friendship without losing it, when to have the honest conversation with an underperformer you inherited, how to deliver a decision you argued against, and how to write a review for someone who once reviewed your code.

Every chapter contains the actual words. What to say, what not to say, and what happens next if you say it anyway. By day ninety you will know whether it is working, and what to fix if it isn't.
