But resources are what you are, hoss. Sounds like the youth of this manager got you messed up. Old head move is to pull him to the side, with the sotto voce, give him a chance to show you he is open to feedback. How can he change now without losing something? This is workplace 101 stuff.
Good attempt at tone policing, I'll grant you that.
You can keep calling yourself whatever you like, or more to say, swallow whatever little pride you still have. But I don't subscribe to that and I won't be called a tool/object/resource in my presence.
