recall list (furloughed)

does anyone know if they can really release all the flight attendants that didn't respond to the possible recall letter? i'm in school now, so it doesn't really matter in my case, but it just seems like a way to get rid of alot of f/a's at once? i know people should have responded, but with all the crap we all been through, just seems kinda sad if not returning one letter could end a career. i tried to find out info. earlier, but really didn't get any reply's. thought maybe someone on this thread may have some answers. how many f/a's are out of jobs now because of this? and can they fight it??
