Author Louis Hyman, a Cornell professor and economic historian, notes that in America traditional organizations began moving away from offers of full-time employment and toward more-flexible short-term staffing jobs as a result of both new management ideas (such as the Lean Revolution) and changing values (such as prioritizing short-term profits). This restructuring of the workforce was facilitated, he emphasizes, by management consultants, who believed that “the long hours, the tensions, the uncertainty were all a perfectly reasonable way to work,” and by temp agencies, which created pools of standby, on-demand labor. By the 1980s temps were providing not emergency help but cyclical replacement.
