The discussion here is missing one key metric that HR uses: Every O employee has a "Loyalty Index" (LI). Oracle Adv Analytics (OAA 10 yrs ago, which is now OML) developed the tracking of LI over a decade ago for HR, and they license it as part of the Human Capital Mgmt (HCM) suite to end customer HRs as well. For anyone still on the inside: look up "Charlie Berger" ppt presos from 2015-17 [CB was the Sr Dir in OAA who developed the tool]. This LI-characterization tool pre-dated LLMs, but uses Natural Language Processing (NLP) and "Sentiment Analysis". HR's tool tracks every employee's login/out hours, keyclick activity throughout the workdays (and off hrs too); all web links everybody goes to on their O-laptop, and parses all emails for phrases that signify high loyalty, or "bored/disgruntled and looking around" sentiment. 2 yrs ago, O added the modified O-Zoom that sends a transcript of all O-Zoom calls to a big database of Z-transcripts, which is also parsed for sentiment/loyalty phrases. [We all got a notice from CorpArch when auto-transcripts of all O-Zoom calls started going to HR+SEC, whether the host records the calls or not].
Consequently, an employee can be marked a 2-3 but have a high LI and be dedicated to improving and doing good for O; whereas a "5" with high raises and RSUs can be getting bored and looking outside for new adventures. Employees with the lowest LIs are at the top of the layoff ranking lists that go from HR to the M7's.
