And Marc that's also what really good employees who leave because they're not listened to always think on their way out the door.

Everyone who isn't listened to is, in their own mind, really good ;)

Jeff Immelt, CEO of GE said this recently:

Every idea begins with a constituency of one. There’s probably one or two times a year that I turn to our very top leaders and say, “we’re going to do it my way.” Do that too often and good people will leave. But if you never do it, nothing ever happens.

This is a bit callous, don't you think?

Actually, I don't. Disruptive employees invariably have an internal narrative in their own minds that says they're attempting to speak truth to power. In reality they're using that as an excuse to be disruptive.

Wait, disruptive in the bad sense, right?

I almost had Bingo.
