tl,dr: Yes, a number of Verily employees are about to apparently leave. They are not being laid off.
To avoid the problems of the non-insiders confusing the issue, I'm going to state what is happening in simple terms:
Alphabet is a conglomerate, with multiple companies (bets). Google is one such bet (and the big one). Verily is another. For various reasons, Verily employees (and employees of some other bets) are tracked in Google's HR system. They have @verily.com addresses but they also have @google.com addresses. The appear in internal employee listings.
And, most significantly, by being tracked in Google's HR system they would appear in the list of departed employees available at the internal site everyone knows about by now, you know, the one where employees get to leave goodbye notes.
That's changing this week. Verily employees are being migrated to Verily's own HR system.
Almost all Verily employees (with a few exceptions) will be "termed" in Google HR, simultaneously being hired in Verily's HR system. As a consequence, the internal site with the list of departed employees will be flooded with Verily employees. These employees ARE NOT LAID OFF. This is just administrative nonsense because a lot of Google's HR infrastructure still hasn't caught up to the idea of separate companies being a thing.
To repeat: The large number of Verily employees that will be "termed" in the coming days are not laid off, not fired (probably), and will still be drawing their pay (probably). They might end up with a cr-ppy 401(k) in the process or something, that much I don't know about.
Anyone who says otherwise is ignorant or a troll.
