I would take this from an employee perspective...
While I do not discount the benefit of continuous personal development, I have serious reservations against advising the "average joe" towards jumping into additional training without considerable thought. I have two points to make:
The first point: You likely lost your job (or hours cut) because the company needs to cut costs, not because you are not talented enough. If talent was the problem, you would have either not gotten the job, or would have lost it without the recession. I think that many people feel that if they can beef up their skill sets, their value to the company will increase. This is faulty due to two reasons. First, not all businesses have an administration that attributes skill to value. In my company, there are many people who share a common set of skills. Those people are valued because they do the job administration assigned them to do, not because they have X number of skills; and while performing the job optimally brings a smile to supervisor's faces, if a company is trying to stay afloat financially it will likely come down to cost. If you cost more, and you share similar skill sets/performance, you will be a target. If you have unique skills, and you are afraid of losing your job because a recession is forcing your company to cut costs, then training is of little value because even if you did have those new skills, your addition to that new team just keeps costs the same or increases cost RT bringing you up to speed.
(This is different than a workforce productivity assessment, which is only beneficial if what you are making more efficient can take you through the economic downturn. The training adds up.)
The second point: Training costs time and money, both of which you cannot get back if you cannot secure a job once you are finished with your program. Case and point, I am considering getting my MPH and the #3 nationally ranked school for Public Health, UNC-Chapel Hill. Even being in the top three, the Director of their Executive program informed me that all hiring for their new MPH grads has stopped. So, I have to be very careful spending money that I cannot get back (because I have either been laid off or reduced work hours), and time that I could use towards looking (or praying :) ) for another job.
Even with smaller training programs that cost significantly less than college, you have to ask yourself why you train? Is it to make a hurt ego feel better about being laid off/reduced? Or is it to apply towards a predicted growing market? Especially in these times, there are a LOT of "big fish" in the hiring pool. Even the best predictions are factoring in an amount of risk, and in that light, while being laid off will certainly give you time to polish that old resume, I would not proclaim continuing education as a guaranteed best investment. It is only useful if you calculate & justify the risk of time/money spent :: probability of hire.
