Yes but,
I agree with this article.

Yes, but. HR reps are required to keep and document some information, and retain that information, and are subject to legal discovery. While you can say the same about e.g. e-mail being recorded for everyone in the company, I personally consider this a higher bar. (It's also "enriched" data - no one has to put together 30 streams of e-mail and try to figure out what's going on.)
If something is amiss, if you're having any sort of problem in the company with another, make HR aware. You don't have to follow-up, you don't have to document it or ask for their intervention, but ensure that HR is aware at the earliest opportunity. If something happens later that appears to be an escalation of this, you have documented evidence of a timeline if needed, for internal processes or external legal processes - and they're required to document it and it will be discover-able. It also gives you something to reference, and perhaps even something to reference back on when you're explaining to HR that an issue is growing your concern, "what should I do here?" Make them tell you, and record, what you should do in that interaction. If they tell you to break the law, it'll be documented, right? :-) So they won't. (If they do, it was a company order, doing your job, documented the problem, yada yada.)
Overall, ensuring that things operate smoothly is in the best interest of the company. Ensure problems are resolved, ensure that they don't develop, don't escalate, and don't become dirty secrets. Use the HR team -- they're responsible for ensuring that you don't have a problem. Use them _early_ so that you don't end up being a _problem_ that they have to deal with.
Personal take: If you're having problems at a company, whether from HR or managers, or even just multiple coworkers, perhaps you shouldn't be at that company. Perhaps you should leave of your own accord, before things get bad. Look for something else while you bide your time, and GET OUT. I mean - the alternative is forcing their hand, right? That means you're a problem.
