Fire them?

I believe it is getting close to this. Things like this just take time though, and when this person talks to management/leadership they talk about how much they are producing and how everyone is blocking their work. So it becomes a challenging political maneuvering depending on the ability of certain leadership to see through the BS.

(By my organization, I meant my company - this person doesn't report to me or in my tree).

This is not really an option for your standard IC.
