In my center in St. Louis Mo they put up 15 jobs, mainly as revenue recovery along with hub sort. there is something everyone should be aware of though. they also included along with the these jobs, "work as directed."
Be carefull of these three words. Work as directed is exactly as it says. it means they could have you do any job in the building such as loading or loading and you cant do a damn thing about it.
As far as hiring freeze, they put jobs up a month ago and from what I heard, they havent filled the jobs. I heard that the company is pissed at the union during the negotians and this is their way of getting back at them.
