100% this. A former coworker was fired a month ago because he filed an HR complaint about his boss, because the boss was being an asshole to him (according to co worker).
This is the same boss who joked about beating his wife and kicking his dog in a meeting, so I’m fairly certain it’s true.
HR is NEVER your friend.
Vaguely related, but there is an awful movie released that tried to capture that sweet sweet rollerblade money in the 90s called Prayer of the Roller boys.
