Kevin,
Glad to hear you made the grade! It does not matter if you are white collar, blue collar, no collar....this economy is effecting every industry and probably every company out there. Like you said, make you self indespensible and you will have a better chance, although never immune. I worked in banking for 20 years, lost my job twice. Not a good feeling when you have mouths to feed.
Sorry to hear you are considering downsizing your system or leaving altogether. You have always been great at giving timely advice to the RC masses.
Good luck and don't let it all get to you!
John
