This is for any executive management lurking out there - you laid a bunch of people off. The damage is done, a lot of us are miserable. Congratulations.
Own it. Stop with the secrecy. Broad communications at a company level that they happened and let managers email about impacted lines of business. It's hard enough to watch your long time coworkers and friends lose their jobs, but it's even harder when you're firing people and not communicating and leaving the rest of us to scramble. Own your decisions and be transparent about them.
