I voted no.
For starts, if any of you actually KNEW the type of people who were "Bums" you'd know that most often they're not sitting on Jobseekers allowance. Thats too much effort because on JSA you already need to prove your looking for work, need to go for a meeting every week (or fortnight) with them and show them what jobs you've been applying for.
No, what they do is get themselves signed off sick, because that way they only have to make a doctors visit every 6 months for a new line. No weekly trips to the job centre, no annoying wifey hassling them etc etc. Plus if they're signed off sick, they're also unable to go and do manual work in the streets, because being signed off sick by definition says you CANT work, even if the true reason is that you wont. (and i'm not for any second suggesting everyone on the sick are taking the ****, far from it!)
So this is largely going to completely unaffect those types of bums that most of you are referring to.
True, some of the bums are on JSA, perhaps the ones not crafty enough to wangle a sick line, but even those know how to play the system well enough that these schemes never affect them, for instance you start a job, then get sacked after a week or two. This then counts as starting a new JSA claim, so you end up never having been on JSA for long enough to trigger the voluntary work scheme (which requires you to have been out of work for 4 months or whatever).
You need to remember some of these people are 2nd and 3rd generation scroungers. They know EVERY trick and scam in the book and they know exactly how to work the system so they never get caught.
So what are you left with... Regular working folk like you or me, who simply cant find work, either becuase they have limited skills, or because there is no work available that aligns with their skillset. The JSA system is already bad enough that skilled people are already forced to look at other professions just to sign on, for instance i hold a computer science degree, and a few years ago i signed on for a couple months while looking for work. When going thru the application the woman asked me for three work categories i'd like to look for work in, and I listed three different IT related roles. The woman looked at me as if i was stupid and said "you cant choose three things the same", i tried suggesting that a sysadmin was nothing like a software analyst, but she basically said "tough you cant do it" and i ended up putting down "Car Audio Installer" and "shop worker" as well.
Given all that, and that its only likely to affect the people really looking for work, it shouldnt be made worse by forcing them out onto the streets. Ofcourse the usual newspaper rags will ensure the public percieves these changes as though they're going to tackle the workshy, when infact they wont.
