I think it depends on the size of the company and who ends up being involved in the decision amking and when.

From what I have seen, the amount that someone is making can be a contributing factor. Maybe your performance reviews but that doesn't always paint a full picture of your actual performance since those are often kinda black and white.

In every layoff I have been a part of (wether or not I was personally affected) the managers found out the morning of and were not consulted before it happened. In more than a few cases someone critical was let go.

Making it mostly a numbers game.
