The Labour jobs guarantee will focus on youth unemployment, the Shadow Secretary for Work and Pensions told Daybreak.
Rachel Reeves said the jobs guarantee will force under-25s who have been out of a year into a minimum wage job, but will only do the same for over 25s after two years on jobseekers allowance.
"We know that there are particular problems with youth unemployment. 20% of young people are out of work - much higher than for the population as a whole.
"And for young people what we hear time and again from them and from businesses, is that there is quite a risk - they haven't worked before.
"But that is not quite the same for older people, which is why we are targeting this scheme at younger people."
Shadow work and pensions secretary Rachel Reeves is to announce plans for a "basic skills test" for all new benefits claimants.
She is expected to say in a speech this morning:
Labour's shadow work and pension secretary Rachel Reeves has asked "when will the PM and IDS [Iain Duncan Smith] get a grip" on Universal Credit, after Cabinet Office minister Francis Maude admitted to ITV News that its implementation had been "pretty lamentable" so far:
Shadow work and pensions secretary Rachel Reeves said the delay to the government’s Personal Independence Payment programme was the "latest example of chaos" in the Department for Work and Pensions.
She said: "The delivery problems we are seeing at the Department for Work and Pensions now risk descending into farce.
“But for thousands of disabled people who are already extremely anxious about the changes, this is no joke.”
Labour will be tougher than the Tories when it comes to slashing the benefits bill, Rachel Reeves, the new shadow work and pensions secretary, has insisted in her first interview since winning promotion in Ed Miliband's frontbench reshuffle.
In an interview with the Observer, Ms Reeves said: "Nobody should be under any illusions that they are going to be able to live a life on benefits under a Labour government.
"It is not an either/or question. We would be tougher [than the Conservatives]. If they don't take it [the offer of a job] they will forfeit their benefit. But there will also be the opportunities there under a Labour government".
Shadow chief secretary to the Treasury Rachel Reeves said the Conservatives "have shown once again that they only ever stand up for a privileged few not for hard working families” following George Osborne's conference speech.
Ms Reeves continued: "The few things he has said are already unravelling. His panicky announcement on fuel duty turns out to be just an aspiration if he can find savings elsewhere.
"The IFS [Institute for Fiscal Studies] has said the marriage tax break will help just 28 per cent of married couples and only 15 per cent of families with children.
"And his work scheme turns out to be less ambitious than Labour’s compulsory jobs guarantee."
Last night's closing credits of Newsnight acknowledged the gaffe by its editor Ian Katz after he accidentally tweeted that Labour's shadow Treasury minister Rachel Reeves was "boring" and "snoring."
The former Guardian deputy editor meant to send his remarks in a private message but instead posted it to his 27,000 followers.
Mr Katz issued a written apology to Labour and Ms Reeves for his comments.
Labour's shadow chief secretary to the Treasury, Rachel Reeves has reacted to Britain's credit rating downgrade by the ratings agency Moody's:
The shadow chief secretary to the Treasury, Rachel Reeves, has revealed she is 14 weeks pregnant.
The Leeds West MP, who is due to give birth in March, has pledged to continue to support her constituents.
“I will take a period of maternity leave and continue to be here for my constituents", the 33-year-old told the Yorkshire Evening Post.
“I think it’s possible for mums and dads to balance being MPs and being parents."
