At this point a firing or layoff might as well just be a text message: "You're fired. K, thx, bye". Any words beyond that are just fluff anyway. To the person getting let go, it really doesn't matter if the decision caused the CEO to get ulcers, or if it was the easiest decision ever. Executive teams only take responsibility in words.
I understand your point, but employees do need to know a lot of important information that cannot be communicated like that e.g. health/dental benefit lapse, severance, references, etc.
It is actually really important in mass layoffs to have this information immediately to hand.
