I don’t know much about it her particular case but have had mean bosses (like one guy thought it would be funny to drug me with something, no idea what, when I asked for an advil - it was in a different country, he told me that’s why it looked different; another would scream at grown men until they cried). I have known lots of people whose lives were terrorized at work by monsters who knew they needed the job and had to take it. It’s not ok.
