A new study shows the CEOs who fired the most workers during the economic recession have also taken home the highest pay. According to the Institute for Policy Studies, the CEOs of the fifty corporations responsible for the worst layoffs were paid an average $12 million — 42 percent more than the average for the Standard & Poor’s 500. The study covered the period from November 2008 to April of this year. For 72 percent of companies, layoffs were announced at the same time as earnings were increasing.
