If you were trying to get in under the wire to opt out, you may have already been out of luck anyway (too many volunteers by last week). Guess those that were still on the fence made a quick decision after seeing the disaster in Japan so HR was deluged with volunteers on Monday-people were lined up outside HR staff offices all day-and now they have way more employees exercising the option than they ever thought in their wildest "you shold be happy to have a job" dreams (we all know how dysfunctional and delusional those managers in HR really are).
Guess they're too busy now to answer their phones as they scramble like rats in a cage to draft those severance letters. Too bad.....
