HR is and will always be on the side of the organization - despite any fluffy language they may tell you about how they’re there to help and protect employees. Any HR person who tries to represent themselves as otherwise is a snake.

Source: worked HR over 10 years. If there’s someone I had considered a friend or felt was honestly in the right and about to get screwed by the company - I was always happy to give off the record advice to help them. In my professional capacity, however, it was always about the organization.
