The next layoff will most likely be corporate folks. TN and Technology have already been hit. I don't know if AS was ever hit yet. The next to get his is corp (HR, Finance, etc.). Don't know the official date, but my guess would be the march date. I can't imagine they'd do it as soon as Feb.
The once thing that pisses me off is they are trying to get around the WARN requirement by having all these staggered layoffs, even they the strategy has always been to layoff people.
