Of course, your mileage may vary but first, if it takes an average of four months to find work, make sure you have 3-6 months worth of living expenses saved in an emergency (low/no risk) fund. Most financial gurus will suggest this. Second, if multiple recessions will likely occur during your career, anticipate them by doing (constantly) those things that enable you to hit the ground running if you’re looking for a job. Always keep your resume updated (a “living” resume) with your skills and achievements as they occur rather than testing your memory years after they occur when you’re dusting off your resume for a job search. Keep your skills current. Don’t wait for your employer to send you to training or give you a spot on a choice project. Learn on your own and/or donate your time to organizations needing help with what you do.
And finally: network, network and network some more. Got it? Don’t wait until you’re looking. Do it as a common practice. Go to lunch, breakfast, dinner or coffee with people. Join organizations relevant (or not) to your field and take an active role with at least one at any given time. Open your mouth and let people know what you do. You would be surprised who your neighbors and acquaintances might know that could help you find a job when/if the time comes.
In short, do the things that you have control over. You probably won’t be in a position to influence company policy relating to adjustments in the work force, but you have complete control over how successful you’ll be landing your next spot.
