What does it mean when a Chinese employee takes on extra work voluntarily?

It is 6:40 p.m. on a Friday in Hangzhou, and the weekly wrap-up meeting is almost over when Director Wang lets a sentence hang in the air: headquarters wants a market-entry analysis by Tuesday. He doesn't assign it. He simply adds, "If anyone has time this weekend…" The silence lasts about three seconds. In those three seconds, everyone in the conference room performs one of the fastest social calculations in the Chinese workplace.

The three seconds of silence were not hesitation — they were a calculation that would decide who volunteered, and what the room would remember.
