Yeah, ideally those who raise their hand would get their wish, but I suppose from a company standpoint, they want to make that decision because many of the folks raising their hands are probably in a position to gain big fat severances; one that will carry them through long enough to find another job (which is about one year, in this economy; no joke!). So, very expensive to let all the hand-raisers go, who want to go. Much cheaper to let a lot of the newbies go, 'cause they won't cost so much. Then, the hand-raisers who get stuck having to stay around either have to work enough, or get fired (and thus, not as much cost to the co.)
Or, they just get bullied enough and quit on their own....no severance.
We are all just numbers plugged into equations. That's it.
Lots of considerations. And yes, there are probably SO many people raising hands, that they wouldn't have anyone left if everyone accommodated!
Bad part, you beg to be let go, but they keep you...mgt knows you don't want to be there, so you are being watched like a hawk. No win situation.
