Cable warns of exploitation of zero-hours contracts
More workers are employed under "zero-hours contracts" than official estimates suggest.
A study by the Chartered Institute of Personnel and Development has found that a million people could be on the contracts which offer no guaranteed work or pay.
A number of councils and well-known businesses use them as well as many in the voluntary sector.
The Business Secretary Vince Cable has told the BBC that he is prepared to take action to stop employers abusing these contracts.
James Landale reports.
