Let's say one employee was publicly harassing another employee. In theory, a manager would talk to each of them and get to the bottom of the issue. It's hard to imagine a scenario where an employee doing this public harassment ought to still be kept employed but that's neither here nor there.
So let's say after the manager talked to both of them, both parties were satisfied with the outcome. Divulging the details of the discussion could be an invasion of privacy but, on the flip side, since this harassment was done in public, the people who witnessed the harassment might, themselves, need some reassurances that all was well, as well.
My question is... how do you reassure witnesses to something like this without violating the privacy of the people most directly involved?
