I'm guessing he has in mind something more like 'minimal number of people on JSA'. It's just "full employment" sounds better. So, make it very hard and unpleasant to claim, sanctions at the drop of a hat, yet wider spread of zero hours contracts, lots more workfare, people going self employed and scraping by etc.
"Mr Osborne declined to define full employment, but said people between jobs or unable to work or with caring responsibilities would not be included."
So yeah, I'm guessing it's mostly related to JSA.
I can't see a Tory being bothered about making sure there's lots of new, well paid, good work available. These are people who think we need a race to the bottom.
