When your gut says something’s wrong at a job, speaking up early is safer than waiting for proof that hurts someone.

Waiting for proof means waiting for the harm, because proof is usually the thing that goes wrong. An early concern is cheap to raise and cheap to be wrong about: somebody checks, it turns out to be nothing, and the whole episode costs an awkward five minutes. Being right too late is a different kind of cost entirely, and it does not land on you alone.

Raise it as something you noticed rather than an accusation. Write down what you saw and the date, keep your own copy, and say it to the person whose job it is.
