I'd like to see resources put into decent full time training schemes for the unemployed. At one time they did briefly exist, at least in some areas.
When I was unemployed in the early 2000s I took a 3 month long course in PC skills for business admin that led to an NVQ level 2 and 3. It was essentially training in MS Office - getting a sound grasp of the basics then slightly more advanced stuff like setting up mail merges and databases and writing Excel macros etc.
While I was doing the course I didn't have to sign on or prove I was looking for work - the deal was you put the required effort into the course and the Jobcentre left you alone. It was really well run and pretty much everyone completed it successfully.
I didn't get a job straight away but I was able to secure some voluntary work that in a roundabout way ended up to my landing an admin job with a national charity (sadly since made redundant following a restructure.)
AFAIK there just aren't those kinds of schemes running any more. There are crappy 'Employability Training' schemes which basically amount to sitting in an overcrowded office for two weeks while some spiv in a shiny suit shares such startling insights as make sure you arrive on time for an interview and don't leave any spelling mistakes on your CV.
Then there are apprenticeships, but those are largely aimed at young people and you're competing with loads of others to try and even get one - and when you do, you risk being used for cheap labour rather than receiving decent training with a recognised qualification at the end of it. It's a bit of a lottery.
IMO the gov should look at what employment areas are actually still growing and what skills they require, put together some credible training courses with a credible qualification at the end, then get people on them ASAP.
As it is, the mentality seems to be lets get these lazy scum off their arses into the shittiest lowest paying jobs possible cause that will show them what's what! It's all a bit race to the bottom.
