Leads across Google are sending coordinated emails within their orgs announcing layoffs. They've all gone out in the last 2 hours or so.
They've fragmented the layoffs on purpose to make them seem more localized, but it's affecting the whole company.
Orgs that I've heard/I'm part of that have been impacted so far include Ads, Search, Assistant, Maps Android & Core.
I'm sure there are more, but I can't confirm.
I can't find WARN notices yet, so I assume they haven't been filed yet in any state.
