By John S. McClenahen The next U.S. Labor Department employment report, containing data for August, is due to be released Sept. 5. That's probably too early, however, to show the significant growth in U.S. jobs that futurist Roger E. Herman says is coming. "A sufficient amount of economic growth will occur during the latter part of 2003 to drive noticeable growth in available jobs," predicts Herman, CEO of the Herman Group, a Greensboro, N.C.-based consulting firm. "Early 2004 will see this trend grow significantly, causing turbulence in the employment market. The increasing job churn will serve as a catalyst to shift labor from a buyers' market to a sellers' market," he says.
