I have been around a long time in the industry to realize never to approach HR against your manager, never seen it work for anyone, on the contrary, it creates bigger problems. As a matter of fact, I have left Dell, the reason was my manager. He created so many issues that I was left with no choice, but to depart. I discussed the situation with another manager in Dell (different group and location), who advised me to approach HR, however, I chose to leave for a better work environment elsewhere.
Good advice from @XgZpKPq-1zzz.
