different scenarios

1. 某某是你的顶头上司: never happened. always have agreement with my boss beforehand
2. 某某是你的上司的上司: happens all the time. yell back if I am certain I am right. He always smiles when I shout back. The prerequisite is that he knows I am not a very calculative person.
3. 某某是你的平级，是你的竞争对手: calmly fight back, with good reasoning and suggestions. Make sure boss sees that I am trying to be collaborative and constructive.
4. 某某是你的下级: say we will address this afterwards. let's move on for now. But this never happens to me. My reports know they can't win arguments with me.
5. 某某是你的顶头上司的同级，是你的上司的竞争对手: sarcastic and ridicule the person severely. There is no reserve here.
