answer:Bullying masquerading as “leadership.” Suck-ups, especially when they’re supervisors who mistreat their staff as a way to show off to higher-ups who aren’t smart enough to see they’re being gamed. I can’t tell you the worst experience in detail because it would reveal where I used to work, but basically I was reamed out at length and high volume by an incompetent supervisor for not doing something she’d never told me to do, while doing tasks I’d never done before and been given no instruction in. This occurred in front of others, in a foreign country at the start of a long stay there, with no one around who was willing to risk her psychotic outbreaks to stand up for me. I still wish I’d punched her in the head.
