There's no rhyme or reason to it. A (very good) manager at my location had stripped her office of personal effects and was hoping to get a package. She had been taken off a major project a few months ago, and she thought for sure that was the last nail in her coffin. She's still here, and her counterpart, who we all thought would not get laid off, is gone.
