You know that colleague: the one who acts a certain way when your boss is in the room but sings a completely different tune when you’re alone. This can be especially frustrating when your boss is blind to this chameleon-like behavior and gives your colleague praise or even promotions. You may be tempted to call out the inconsistent behavior, but before you do anything, take the time to understand why the person behaves the way they do and what can you do about it.
