Updated:The Daily Digit is 7.9 million. This is how many people were working part time in April because their hours had been cut back or because they were unable to find a full-time job. That's 278,000 more than in March, the U.S. Labor Department said. Julia Coronado, Chief US Economist, BNP Paribas says it is a problem. "We are not using those people's skills, and we are not generating the income growth that full-time jobs would bring."
