OK, don't worry and be happy - here it is, 4 weeks of pay, 18 months of COBRA, and faster vesting if you are in the priviledged pool of folks with stock options. Overall, not bad, really...
If you are in non management positions this will be hard to accept - there is not enough incentives but if you are close to your magic retirment number maybe.
Relax and do not worry :-)
