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. 某某是你的平級,是你的競爭對手: calmly fight back, with good reasoning and suggestions. Make sure boss sees that I am trying to be collaborative and constructive.
4. 某某是你的下級: 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. 某某是你的頂頭上司的同級,是你的上司的競爭對手: sarcastic and ridicule the person severely. There is no reserve here.
