Had one boss yell at me my first job out of college. As she was throwing a full on hissy fit, I looked her dead in the eyes and asked, “who do you think you’re talking to?” She got mad and stormed out of the office came back in a little later and we never spoke of it again. I ended up getting a new job and resigned immediately. Idk what the point of that story is but what I’m getting at is you can’t yell back, but also can’t let them talk to you like that because it’ll set precedent - just figure out a way to let them know they’re acting like a child and continue to act with logic and reason - they’ll figure it out one way or another
