I get what you're saying, but it's a dizzying problem - the proximate problem to HR in these scenarios isn't that people think HR is bad or worry they'll relay the complaint, it's that HR has no teeth.
At Google, I had an...unusual...de-facto manager for 2 years. After declining their offer to join their team, they spent six months engaging in behavior that violated company policies - though not in obvious ways like sexual harassment or violence.
Going to HR seemed futile. Even assuming they could keep anonymity, their role is simply to investigate and report to management three levels up. Without clear-cut violations, it becomes a credibility contest. Since upper management selected the middle managers, they're inherently biased toward defending their choices.
The situation came to a head between December 1st and January 1st. My performance rating plummeted from "O" (top 10%) to "MI" (bottom 10%) and a technically separate formal warning. Things came to a head because they were nominally leading work that was a huge political warzone between organizations, and they didn't really want to do anything. After I politely demurred their invitation to transfer, they hired a childhood friend as my replacement - they're still launching "new" features with the code I wrote two years ago.
I documented various incidents over those six months that violated Google's code of conduct. But even in the best-case scenario:
- HR confirms the violations.
- They report findings to my third-level manager.
- My second-level manager (who chose my de-facto manager) blames me.
- The third-level manager (who chose the second-level manager) defers to their choice.
I entered Google wondering how they handled professional disagreements. (I was a young CEO for the 5 years prior) Seven years later, I realized they don't - disagreement itself is seen as inappropriate. This dynamic inevitably hurts those lowest in the hierarchy. It's not malicious; everyone believes they're acting appropriately. But once anyone decides to prioritize comfort over strict policy enforcement (a natural human tendency), standard human politics take over. I honestly, swear to god, saw this in abundance at Google in ways I never saw at a fast food job.
What I once dismissed as complaints from underperformers now seems depressingly accurate.
