I can confirm what @H6FWgsy-1ppi says, I was in HR and was one of the HRP's who was tasked with "ethically influencing" managers to scrutinize their Focal ratings. I challenged the way we were directed to hammer on the managers about perf msgs for URMs with my manager in multiple situations. I disagreed with forcing mgrs to impact non-deserving people over those who were URM when URM had very clear perf issues (documented).
Having said that, I also strongly advocated for URMs when I saw managers inappropriately rating them. If I saw 2 ee's same grade, same position, but non-URM consistently getting high ratings/ssl an opportunities, I would contact the manager and make them provide me both SELF assessments of BOTH ee's, then I would ask to see manager's assessments and SO's to ensure they were setting all ee's up for success equally...if manager purposely removed/altered accomplishments of the URM evaluation in order to disadvantage them, wasn't providing growth opportunities, or couldn't explain how the non-URM's contributions had more impact than URM, I would make the manager change the rating...not only that, I would follow up with the manager throughout the year and periodically have them send me their 1:1 notes so that I could give guidance when necessary - I applied this logic to all inequities I identified regardless of the ee representation status. I actually took the time each Focal to analyze the data to the lowest level to identify anomalies...and kept informed of their progress throughout the year.
I flagged what I believed to be reverse discrimination by one of my peers...in the following Focal I received a BE and was told that I needed HR certification from ShRM in order to uplevel my HR skillset and that I was not fulfilling my duties as an HR Professional. Pretty much, I got performance managed for directly challenging the diversity program as well as the judgement of my manager. I believed that doing what I've just described was noble, I had applied this philosophy fairly regardless of URM status. And, being a URM twice over myself, and seeing the way I was being treated yet watching HR make managers do the opposite... I was so appalled at the way diversity initiatives were forced that I left the group and never viewed Intel the same. I am a huge proponent of embracing and leveraging diversity, but NOT in the way Intel drives the initiative. I've since left the company and have never been happier.
