It'll help the company shed any remaining slackers, increasing attrition to get the headcount where it should be.
Say whatever about Pat, but he fought to retain headcount in the recent CPM festivities. That's one of the reasons Lip-Bu-Tan resigned.
Aside from getting headcount down to something like 80k, and shedding some pointless product groups, WFO does help team coherence. There is no valid debate about this.
Intel needs cohesive teams more than ever, so get on with RTO and try to rebuild from this stupid pandemic era idiocy.
