Done correctly, a lot of what HR does is never visible to the employee. “No, the law won’t let you do that” style correction before a bad policy can be implemented.
Yea, whenever these HR stories come up I always think to myself: who are all these people where HR is part of their day-to-day? Maybe I’m extremely lucky. Almost all companies I’ve worked for, I’ve interacted with HR twice: once on my first day where they hand me a bunch of papers to sign and once more on my last day when I turn in my badge. That’s it! Otherwise they are totally invisible, and I have no idea who they even are!

This post is _especially_ for folks like you. When something shitty happens at work, you might contemplate contacting HR for the first time in your life. This post is a warning: HR defends the company's interest, not yours. They are not a neutral court of appeals.
That might be the whole reason: Once you're interacting with HR, you usually do so because you have a problem (you did something wrong, there was a conflict with another employee ...). In those cases, you're far more likely to not have a good experience (I presume).
