In all companies, and conveniently only when layoffs are affected? I have some doubts. Most people think their own contributions are invaluable, and when they or someone in a similar position get laid off, that challenges that self-image and the obvious explanation is: their perception is completely accurate, but the others are idiots and cannot see it, or they see it, but are ruled by perverse incentives that make them kill the company instead of doing The Right Thing (i.e. keeping and promoting the employee). It's understandable, but I don't see much value in that line of thinking.
