"Official figures are masking a growing crisis in the labour market, with only half the vacancies advertised in UK jobcentres guaranteeing enough hours to allow jobseekers to qualify for the government's new in-work benefits regime, a Guardian investigation has found. The analysis of 112,000 Jobcentre Plus vacancies shows that only 52% of the positions guarantee enough hours to meet the new government definition of "work" for a typical family. It means that some working families are likely to be far harder hit by the controversial changes to working tax credits than previously feared by being caught in a new working-hours trap, and raises concerns about the quality of jobs being created in the economy." - M F
