I know EMC used to fire 10% of their workforce every year, it was stupid but that's what they did. My question is if these people hadn't been pulling their weight why did you wait so long to chop their head? I see it at my company where groups will keep dead weight around just so they have someone to fire when management wants a head, again it's silly but it's better than having to fire a productive worker that actually will effect the bottom line if they get fired.
