They say
“You told me I was ready.”
Your response
“You’re right that I said you were ready. I need to explain what changed between that conversation and this decision. If nothing relevant changed, then I gave you reason to expect a different outcome, and I need to own that.”
First, check this
What exactly did you tell the employee, and what decision-relevant information changed afterward?
Why this works
The manager’s earlier words are part of the decision, not a distraction from it. If the role, criteria, timing, or available information changed, the employee deserves a clear account of that difference. If nothing relevant changed, the manager may have overstated what readiness meant or implied control over a decision they did not control. Owning that error is more credible than rewriting the earlier conversation.
Don’t say
“I said you were ready, not that you would actually be promoted.”
