Who has permission to know things?
The American South antebellum had very few organised slave rebellions. What was common, though, was sudden flashes of violence: enslaved people who (to the best knowledge of the slave masters) were content with their lot would sometimes take an axe and murder someone, or poison the family that owned them, or some other drastic act of violence.
While poisoning one's superiors isn't quite so common in corporate settings, this kind of sudden flash of anger often comes up in the workplace: the hard-working woman on your engineering team who suddenly quits, citing a whole bunch of problems that you never noticed, the black guy who suddenly starts quarrelling with people about every piece of work that you do and the trans sysadmin who disappears without warning one day, leaving all your web infrastructure to go down... these all happen quite often in workplaces.
The most striking thing about situations of this kind is that the people whom this happens to are always surprised. They never register than anything's wrong until it's way too late, and when something does happen, they experience it as sudden, insane, irrational rage that came out of a clear blue sky. And then, they're so upset. These awful, terrible, no-good people destroyed their lives for no reason!
