How do you deal with those co-workers who act arrogantly in the workplace?

I often give them four words: "Let it go". There will always be someone who will teach them a lesson for their ignorance and arrogance. Just like the proverb that a scholar can't explain clearly when he encounters a soldier, there are some things that don't need to be explained. , you cannot wake up a person who is pretending to be asleep. Then let them remain so arrogant until society teaches them how to behave.
