What do we do when we've tried giving negative feedback but it doesn't seem to be working? We've given repeated instances of feedback, and yet we don't see a change in a direct's behavior?

We give systemic feedback. And it's easy to give - it's just the four step standard feedback model with a change in focus. If you already know how to give standard feedback, systemic feedback is simple to implement...yet its simplicity belies its power. Really well delivered systemic feedback is exceptionally hard to ignore, and lays excellent groundwork for further efforts if the direct doesn't change his or her behavior.
