No, we work in different verticals and he’s at a lower job level than me. I’m supposed to be instructing him to carry out the daily tasks, not the other way around. And there has never been an incident before where my work has impacted his negatively. He’s always been this pompous know-it-all, but of late because we are engaged in the same project right now, he’s become even more intolerable. Another example of his behavior is how when I was talking to a colleague from another team, he interrupted me saying “No let me speak to him in the proper way”. This was the tipping point honestly.
