The pay gap between senior managers and lower-level employees has widened much more sharply in North America and Asia than in Europe since the financial crisis, a study showed yesterday. The report by Hay Group, a global management consultancy, showed that pay disparity between the likes of clerical or graduate-entry jobs and senior managers had increased in every region worldwide since the start of the global recession. In North America the pay gap rose by 7.2 percent between 2008 and 2014, while the gap in Asia increased by 12.5 percent. Europe experienced the smallest widening at 2.2 percent. "Despite an average global increase in the job-level pay gap, Europe and America have diverged, in part due to local employment practices," Hay Group consultant Ben Frost said. The International Monetary Fund warned last year that income inequality could lead to slower or less sustainable economic growth. Many companies in Europe introduced across-the-board pay cuts to avoid job losses while businesses in the United States cut jobs more often and raised senior management pay to reflect increased duties, the Hay report showed. The pay gap in the United States widened by 10.6 percent between 2008 and 2014, with workers in senior management roles paid an average of four times the amount earned by workers in lower-level jobs last year. Within Europe, the gap in Britain increased 5.3 percent to 3.3 times but by only 0.3 percent in Germany to 2.8 times. In Asia, the gap in China grew by 7.8 percent to 12.7 times and in Japan it rose by 2.1 percent to 3.3 times.
