Xiao Zhang was promoted to supervisor, and everyone was very surprised—he has average professional skills and doesn't work overtime much.

I secretly asked the boss how he was chosen, and the boss said: "Because he's easy to communicate with."
I became even more curious: "What does 'easy to communicate with' mean?"
The boss said: "Whatever I say, he nods."
I was silent. Turns out, in the workplace, "communication skills" sometimes translate to "obedience ability."
