Layoffs are hard. People will be upset no matter what. The responsibility of leadership is to make hard decisions that have the best outcome. Telling 7,000 people they might be laid off this week and so they must stay home so that the company can say “we did a personal call with each person being laid off” is an order of magnitude worse than just sending everyone an email today. People will be upset regardless, a good leader optimises for the well-being of their people, and this approach does not do that.
