But I agree that awareness of the work environment alone causes both of us to keep things civil and within courteous bounds.
Though I'm a little surprised at how my ENFJ boss argues. I may go into a confrontation feeling that there's only one issue in play and expecting to have to defend myself only at the one main point of contention. But after testing me at the main point, my boss will shift about quickly and come at me from six other different angles looking for even very small points of access or leverage. So I have to stay on my toes, watch for subtle shifts in approach, figure out where he's headed, and try to deny or snatch away his objective before he gets there. It's exhilarating; but I can understand your feeling that they just keep coming after you and pushing for more. By way of contrast, Te is much more direct and blunt as you indicated.
Again, I think that demonstrates an ENFJ's tenacity and determination to achieve their own "social imperative" in a conflict situation. They aren't pushovers. There's a lot of testing and maneuvering that gets done before we can get down to the horse-trading and work out the final compromise.
