Had one boss who disclosed a new employee’s diagnosis to the rest of the team in order to discredit that employee’s ability to do their job. Among many many other things. The tipping point for me was her sending out an email (after the employee had already moved on to another department) which was just titled “EVIDENCE OF BAD [WORK]” trying list a bunch of shit that in her eyes had been done badly. This would be whatever if she was emailing it to her own boss or whatever - no, she cc’d the ENTIRE team and it was very clearly done to try to embarrass the employee, who as I mentioned had already left and couldn’t even defend themselves against the bullshit this person was saying.
Also worked at another place where the bullies (who were mental health specialists) bullied a 60-year-old team member so hard that she went home crying. They’d also regularly make ‘team plans’ in office and have ‘team lunches’ where they’d very purposefully exclude one or two people but then very loudly chat and comment about all of it in front of those people. Place was toxic as fuck.
Honestly it was a really rough few months, I think I mostly got through it by trauma bonding with the person who was being bullied, were actually good friends now. After that email, I ended up reaching out to HR because that was the tipping point for me. I left shortly after to another department and there was a full investigation where (for various reasons) the person wasn’t fired but quietly moved along to a different department. The investigation opened up a lot of gates though and that department has gone through some pretty drastic changes to address the toxic culture.
