You are not ignorant, I didn't understand it either.
It seems it is a term used more in British English. I had to Google it ;-) It seems that the term "made redundant" is approximately the same as "being laid off".
You learn something new every day :-)
But I am sorry to hear that. There are so many people without jobs right now and so many firms essentially on a hiring freeze. The best tip I can give is to start looking for contract work until something permanent opens up. It could be a good way for you to learn about different offices and their environments to help you choose and that way you'd have your foot in the door the minute the office you want decides to hire. Good luck!
The term is used a lot here in the USA as well. Whenever there are a lot of people doing basically the same thing this is deamed "redundant" and in tough economies most companies try to cut out the redundancy.
I have always been fortunate to work for companies where I have found myself in a niche being the only person doing what I do. Unfortunately I have no good advice for finding new employment in trouble times. Network like crazy. Think outside the box and perhaps try some freelancing to fill in the time until something else comes along.
So, in essence, many cases where one is laid-off is the same as being deemed "redundant." I'm sure there are a variety of factors affecting the decision for lay-offs, but I'd bet redundancy is the greatest. In a way, this could be taken as a clue to how to prepare yourself and your skill set in a manner to protect yourself from a lay off from the perspective of the employee.
I went through this a little over a year ago. I had been working for a firm that was almost exclusively doing work in residential development in Arizona. Unforturnately, they did not put much into branching out into other sectors and I've learned the department that once numbered 15 is down to 4. I was fortunate to find contract work to keep an income while looking for a permanent position. I did get a position that required me to move, but I was fine with that.
My advice would be to be sure your portfolio is up to date and keep putting yourself out there. Do things to follow up on contacts you make like send a "thank you note". Definitely look at what firms have work and why. Consider volunteering for a firm to add some assistance to get a foot in the door. One thing that helped me was to re-evaluate where I wanted my career and to search that out.
Wish I had some tips for you, I'm dealing with the same thing here in NYC right now. I might suggest trying to get contract work doing anything you have skills in. There may be architecture firms or engineering firms that need AutoCAD drafting or photoshop rendering. Keep your head up, you're not alone out there.
