No, it's not insane. Emotional abuse isn't a one time thing, by several employees. It's a systemic problem because of particular employees with abusive tendencies, and/or toxic company rules. In either case, there is no need for such surveillance to see such abuse from miles away. I'm 100% everyone knew about this ongoing abuse. There would be no need whatsoever for any of the suggestions you mentioned to have prevented this from happening.
