Well then... don't harass people. Saying "My manager Brad really fucked me and the team over with his self-serving decision-making, putting me in a really bad spot which ended up costing me my job, and then negatively influenced my subsequent job search by bulshitting about me to his friends" seems pretty reasonable.

I'm not in the business of calling people out to shame them, but I sure as hell would like to know who sucks at managing at specific companies so I don't accidentally work for them.
