996

In China, its birthplace, '996' always seen as practice of failed management. Because for at least half of the 72-hour workweek, most employee will mentally checkout (in Chinese we call this 摸鱼). Although middle managers know their subordinates are inefficient, they still impose working hour KPI on their team, so they can demonstrate their own value to upper management.

I used to work for Huawei where 996 or worse wasn't uncommon. While middle management definitely pushed for extended working hours, I didn't get the impression that anyone viewed it as failed management. If anything, upper management knew exactly what was happening and was encouraging it.

Hell, you have the likes of Jack Ma glorifying 996, calling it a blessing.
