The number of workers on zero-hours contracts could be one million - four times as high as official estimates, according to new research. Such workers are on call to work when needed by bosses but employers do not have guarantee any hours.
I have just been talking to the Business Secretary, Vince Cable, about zero hours contracts which the government has promised to review.
He told me that although they can work well, he "suspects exploitation" and believes some workers are being taken advantage of.
He said no government would consider banning them all together, but that he is this taking legal advice on zero hours contracts that tie workers to one employer.
Yet the government review, Labour has discovered, is only three civil servants looking at the issue part time. Cable admits this is not a major investigation but "taking a first cut''.
The government is looking into zero hours contracts as new research says the number of people working such contracts could be one million.
Opinion varies dramatically among both workers and employees when it comes to zero hours contracts, as ITV News viewers demonstrate.
