Others are correct. Unemployment varies from state to state. In some (like California) the amount of your severance has no impact on qualifying for unemployment – so long as you did not quit and were not fired for cause, you get unemployment benefits. That's the good news. The bad news is in California unemployment tops out at $450 a week. Yes. In California, with some of the highest cost of living, unemployment tops at $450 a week.
As far as severance, that depends on your seniority and position. Those at the VP level will get a really super fat severance, often 6 months of pay, plus stock grants and other bonuses. Those at the grunt level will see the package vary by years of service. However, anything less than 20 years and you're looking at only a few weeks of severance. Oh, and non executives can forget about bonuses, stocks, or any other "retirement" perks. Those are reserved for suits.
And that is that. You're done, with just enough to keep you going for another couple of weeks before you start to feel the pinch.
But cheer up! At least Randy is getting a $30M buyout plus a $3M per year pension for life!
