Our hero of the day is about to make a mistake... That's OK, because he'll feel comfortable talking about it and will report what happened... and help his organisation to make progress.
And if he talks about what he did wrong, it is because his company has developed a just culture. He knows that his manager's response will be fair and balanced, as everyone knows what the rules are... the essential ingredients of a climate of trust!
Of course, there is still a red line between what is acceptable and what is unacceptable... because above all, the purpose of a just culture is to protect everyone!
