Universal Credit is going to be trialled in 1 area this month onwards. It was going to be 4, but now they've decided that they're going to trial just one area initially.
The criteria for being able to take part in the pathfinder is, according to wiki (terrible source, I know, but everything keeps changing so much that everything on the gov.uk site, etc., is out of date) is:
"-live in a specified postcode area but not be homeless, in supported or temporary accommodation or a homeowner
-be single, with no dependent children, a British citizen and aged between 18 years and 60 years and 6 months
-be fit for work
-not have a claim to Jobseeker?s Allowance (JSA) or Employment and Support Allowance (ESA) that ended in the last two weeks, except where ESA ended due to a decision that you no longer have limited capability for work
-not be pregnant or be within 15 weeks after the expected date of birth; -not be receiving existing benefits (including Housing Benefit) or Tax Credits or awaiting a decision on, or be appealing against, a decision not to award any of those
-not be in receipt of Disability Living Allowance (DLA) or Personal Independence Payment (PIP)
-have expected take home pay no higher than £270 per month (under 25s) or £330 per month (25 or over) and not have savings in excess of £6,000
-not have any caring responsibilities
-not be self-employed, in education or have to rely on an appointee; and -have a valid bank account and National Insurance Number.
The findings from the Pathfinder will be used to make changes (where necessary) to ensure the new service is robust and reliable when Universal Credit goes live nationally in October 2013. From October 2013, Universal Credit will start to take new claims from unemployed people, building up capacity to April 2014, when all new claims to the current benefits and credits will be entirely phased out. The remainder of current claims will be moved to Universal Credit from 2014, with the process being complete by 2017. The majority of claims will be made online rather than by telephone or face to face"
£330 per month equates to £76 per week. That's 12 hours at National Minimum Wage.
So, the criteria is, that you must be fit to work, but anticipating working under 12 hours per week in a minimum wage job. 
AIBU to think that this is a convenient way to herald UC a resounding success, as you've removed all the genuinely able and expecting to work population?
