If you aren't measuring performance than it doesn't exist and doesn't matter. So all you have to rely on what it looks like and personal biases. Most companies don't want to or can't do the leg work for a legally compliant performance related firing. It's easier to bundle everyone into a giant RIF. The downside is the bad performers and the good performers don't get valuable feedback. Good workers assume they are in the former group which feeds their paranoia.
