Leaders get blamed for things they didn’t do. Taking it calmly, then fixing it, is part of the job.

Any position collects responsibility that is not matched by anything you actually did. Things will land on you that were somebody else’s decision or nobody’s fault, and arguing the attribution usually costs more than it recovers. The useful response is not agreeing that you were wrong, it is declining the argument and going to fix the thing.

The next time something unfair comes your way, take it without a speech and ask what would stop it happening again. Correct the record once, briefly, if it genuinely matters. Then spend your energy on the repair rather than the blame.
