I already have done that to a certain extent - my job is about 50% business analysis/design - 50% programming/database. I'm in no danger of losing my job (yet) but I would probably have to take a huge salary hit to stay in the game if I do.
He took a salary cut (about 40%) to take the job he has now. Beggars can't be choosers, so I just try to be careful with our money and hope for the best.
