I'll add to my previous post. Until a few years ago we had some types who were like this. All had skin as thick as rhinos. They just didn't get this modern two pilot sort of stuff. They were totally un-reformable. Fortunately the company they ended up working for was not. They either retired early or got the chop. Your job is to be professional with these numpties. Unless they are going to kill you, take it easy. But always tell them what you are going to do and why. They will probably disagree, but what the heck. Look as this challenge as a learning experience... and let your company deal with them (eventually).
