Somewhat OT, but I never understood why so many corporations have this hard and fast rule that they have to fire (or give no bonus to) a set percentage every year: "We must fire X% of people."
I have worked at a few firms that have done this, and I have heard from a few people their managers arbitrarily picked them to get knocked into a lower tier.
Conversely, if they hired a big cohort of bozos one year, you know they would never say, "We would like to get rid of 15%, but our plan is only to get rid of 10%." They would have no problem going beyond 10%.
