That's modern life!
When the job-for-life thing ended during the 80s/90s we all had to learn to be slashers. I started working in the mid 1980s and I thought I had a solid career ahead of me but by 1992 I was having to learn lots of things, find ways to make a living. It's just life these days, there's no safety net. I have my main IT career but I make money through my photography, selling licenses, selling tutorials and I write books on it. I've always wanted to learn to be a sparky like my Dad and I might go back to college part time to study for a qualification. You need a plan B, plan C and even a plan D. I know lots of people with second or third skills they can fall back on if the IT thing finally goes up in smoke.
