They are a scourge, causing such a big accident, there's nothing more to say, direct death penalty.
The others are at most collateral victims.
The reason why Team Leader Zheng was treated so harshly is that he happened to be involved in the 'first case'.
As the old saying goes, he was made an example of.
In fact, to speak the truth, he was very unlucky, very innocent.
But he failed to manage his subordinates properly and didn't go to the site daily, controlling everything remotely from the data center every day.
This is also a case of 'laziness' causing trouble.
Because after investigation, the problem of machinery aging hadn't just started recently in this factory.
Anyway, after the investigation, not many were found to be good people.
Simply combining everything, they used Team Leader Zheng as the scapegoat, with light crime receiving heavy punishment.
