I was around for a big Microsoft layoff many years ago and it was well communicated internally and empathically. We were given audience (10:1) with directors upon request to ask questions and plead for our fallen. The individuals let go were eulogized with authentic tears by the humans who were given headcount by corporate and then had it taken away. It wasn't the bottom or some biased subset that was culled, but a seemingly random selection across bands to hit a target. (I'm inclined to believe this, given what I saw). We lobbied for our people, and actually got one hired back in a different division that wasn't subject to the layoff.
