A graduate has lost her legal challenge to a government scheme which she says forces people to work without pay.
Cait Reilly, a University of Birmingham geology graduate, had argued that making her work unpaid at a Poundland store for two weeks or risk losing her benefits was a breach of human rights.
The scheme was ruled lawful by the High Court, but letters setting out possible sanctions should be clearer, it said.
The government said its letters were clear and would contest that finding.
Miss Reilly's fellow claimant, unemployed heavy goods vehicle driver Jamie Wilson, was told that his Jobseeker's Allowance would be stopped after he refused to take part in the Community Action Programme, which his lawyers said would have involved him working unpaid for 30 hours per week for six months.
Lawyers representing the pair were trying to get their back-to-work schemes declared unlawful under article four of the European Convention on Human Rights, which prohibits both forced labour and slavery.
The judge, Mr Justice Foskett, however, said this was "a long way from contemporary thinking".
The Department for Work and Pensions (DWP) said the comparison with slave labour was "ridiculous".
