Well, it would be better to say who isn't laying off here in North Tejas.
Nortel, several thousand
AMR (american airlines) like 5000 +
Delta airlines several hundred(or more)
Alcatel
MCI Worldcom(they have (had) a major operation in the infomart in Dallas, like two whole floors, but were down to part of one floor plus their network node on the same floor when I attended a training school there back in June of this year. Nothing but empty cubes in all directions)
Lucent
Genuity
Motorola
Halliburton closed up in Ft. Worth and moved to Houston.
Just about all the telecom companies have been hit hard.
One plus is that Lockheed Martin just got the JSF contract, so that helps a little, but they really wont be adding a lot of jobs till later
Northrup Grumman/ vought aircraft, GE engine sevices(jet/turbine engine repair/refurb)
This doesn't take into account all the small to medium size places that have let people go or folded all together.
With all the IT talent that has been let go, It is EXTREMELY tought trying to start out in the field around here. For me the resumes have been flying, but no bites as of yet..

but I refuse to let it get me down. Plus I have been blessed with Mrs desmocat having a stable job that pays pretty well, with the local gov't so we can make it on just her salary if we have to.
