Agreed. You give employees a heads up that the layoffs will be occurring, which both sets expectations with those who are affected AND also allows those who aren't affected to understand what's going on.

Then you take one of two approaches: If the CEO feels strongly that the news should come from them personally, you do the Zoom call, and then affected workers immediately meet with their managers for individual communication. Or you skip the Zoom calls and have the managers deliver the news.

Obviously, you want the time between the "heads up" meeting and the meeting with the affected individuals to be short, maybe a day or less, so workers aren't spending too much time in dread mode. But it reduces the feeling of having been blindsided.
