Correct, but I'm not talking about Aberdeen as such, but in more general terms across our offices worldwide.
My wife works inside the bowels of academia (and I hover on the periphery dealing with academics), and the stuff that goes on inside that "world" is just shocking.
One interesting industry which is always crying out for people (at least, we have no luck finding them and have to train them ourselves) is railway trackside maintenance. A Personal Track Safety course (PTS) is 2 days (no degree required), and if you then work up to PICOP (person in charge of posession), if you're not bothered about working un-sociable hours/travelling the money is pretty good for a very achievable level of certification - and there is usually high demand.
