This is how this usually works, based on my experience with more than a few of these.
They’ll announce during earnings that there are layoffs coming. There will be broad details as to the objectives of the layoffs and general numbers.
The lists are almost always already drawn up, so people leaders will be informed tonight and will be given the procedure to notify impacted employees. Usually directors and below, and some VPs, have no idea who was picked.
Once the impacted employees are notified, people leaders call their other direct reports to inform them they were not impacted and to please be kind and understanding, etc etc.
Note that some impact notifications may lag, particularly in countries with more robust labor protections where unions or work councils have to be involved.
The only differentiator will be if the lists aren’t drawn up yet, but they’ve made a decision to lay off, in which case that will be disclosed (since it has to be, and if it’s not an analyst will ask and they have to fess up on the call) l and we’ll wind up in this sh---y limbo waiting for the hammer to drop. The last time that happened it was a sh-t show all around, so I hope they’ve done what they can to avoid it this time.
May the odds be ever in your favor.
