Both of my brothers are in similar situations. One was an insurance adjuster for 7 years, got tired of it, and decided to get into network admin. He was doing great for a while, with all the Cisco and MS certifications, but when the economy tanked, he was out the door. That was two years ago. Since then, he's worked as a driving instructor, a software installer, and a couple of other jobs. But no steady income for two years, so he's back living with the folks. And he's 43 and has a BS in accounting.
My other brother never went the college route, but he's good with his hands, and with hardware, so he got into computers about 8 years ago. He also did the Cisco and MS certifications BS, and landed a good job as a network admin. In 2000, he was up to about $70k, the market crapped out, and he lost his job. Since then, he's had nothing but temp jobs, working a week or two here and there and then being laid off for a month. I think he made $30k last year. Now he's finally working full-time as a network admin at a local hospital, but he's a contractor and is laid off every couple of months for up to 3 weeks. No benefits, health insurance, sick leave, nothing. And the hospital is paying the agency he works for $100 an hour, while the agency pays him $25.
The situation today is similar to 1989-1993. When the economy is like this, employers are in a position to screw you, so they do. All you can do is suck in your gut and wait for the next cycle of prosperity. I doubt we will have a return of the pre-Y2K economy, with all that wonderful tech spending, but things will get better.
In the mean time, learn all you can, get as much experience as you can, and when the economy picks up, you're out the door to a better future.
