I've been laid off twice by the same company. lol.
No matter what happens it's for the best. The first time I started my own business and made $97,000 the first year. After getting re-hired 14 months later with a $10k raise over what I previously made, I ended up getting laid off again 2.5 years later. Then I ended up at a much better job that paid $10k more than the first and overflowing with thousands of hot rich girls.
For your sake, you should update your resume NOW, and keep your horizons open for better opportunities. Getting laid off isn't fun, and updating your resume when you feel pissed off and betrayed is really difficult. You're easier to hire if you're already employed, and you will notice that the mood in your office is in the toilet until they're in good enough shape to grant christmas bonuses and go on a hiring binge again. Everyone I know who stayed at the ol' job after the layoffs were completely demoralized and nervous at all times. That's no way to work.
