So many posts without reality of facts. No manager knows a week before who is on list. It’s the process that HR goes through to keep them informed ahead, of what’s coming.
IT probably gets the list first, so they start or already installed monitoring software. Managers get the person (s) list to layoff the night before. At that point they schedule their 1:1 meeting same evening or the early next day. Then they show up for the call, other side is the poor lame employee, shivering and scared, having heard this coming from many sources. His/her heart rate is so high, wouldn’t even notice when the script was read and completed. It’s like being stuck with a high speed train.
Take a day of mourning, gather yourself and let the moment go pass by. By 2nd/3rd day, you are already sending resumes and talking to recruiters. New life is beginning to take shape. Such is life. You will rise again from the ashes, trust yourself. Better things ahead 🙏
