Most people looking to job-hop were hoping for a better job; they weren’t always unhappy with the ones they had. They would leave for better pay or benefits (cited by 52 percent); better conditions or job prospects (14 percent) and better training and development opportunities (13 percent). Only 3 percent said they would leave because of their bosses, bucking the conventional wisdom that "people leave managers, not companies."
The survey was part of an ICR/International Communications Research study conducted in the United States by telephone in July 2004; 217 full-time workers who consider themselves to be middle managers were surveyed.
