What areas of law are the most recession-proof?

I'm one of the newest associates at my large law firm, so I know that I'm one of the first people gone if things go south. I'm increasingly worried about the possibility of an economic downturn, and I want to help recession-proof myself by branching out into areas of law that hold up reasonably well in bad economic conditions.

What areas of law (that a large law firm would be involved with) are the most relatively recession-proof?

My instincts tell me bankruptcy, since bankruptcies would naturally increase during a recession -- plus I know nobody likes practicing bankruptcy law, so there should be plenty of opportunity within my firm. Is that right? Are there better choices?
