Re: Sexing up the good old CV
My own half-a-degree got me out of a post-room and into a Finance job that's slowly turned into the cursed life of a VBA developer. IT is definitely a field where practice and willingness to try and Fix Things can eventually become a job.
AS for entire industry shifts: a friend of mine moved from retail Pharmacy to IT a few years back - retail pharmacy is like regular retail, except your mistakes might kill someone and you're deep in student loan debt to get in the door. She did an HND or something of that order to get a paper qualification, and managed to turn that into a serious IT job.
