Very unlikely. My company just went through a huge round of cutbacks, including axing half my department. They can't afford to axe any more, since we're already barely keeping up with the workload. And most of the cuts were anticipatory, based on projected continuing economic slide, and losing two of our biggest customers (at least one of which it looks like we'll be holding on to). One thing I appreciated is that the top execs took serious pay cuts, as well as suspending bonuses and annual raises; so they wouldn't have to cut benefits for the rest of us.
So barring something seriously nasty happening with the US economy in general, serious screwups by the company costing us more than two of our biggest customers, or seriously screwing up myself, I'm reasonably safe. Not going to be getting any raises in the near future, unless things improve dramatically; but not going to be losing anything either.
