With 14 million people unable to find work and job prospects seemingly bleak, why are more employees calling it quits? In September, about 2 million people gave notice, the highest number of monthly resignations since November 2008. Economic downturns typically decrease worker satisfaction as employers cut staff and pile on the work. Yet the proportion of the workforce that took a hike reached its lowest level in a decade in early 2010 as fear trumped unhappiness on the job. This year, resignations have risen steadily. And as more people leave, employers may finally be forced to hand out raises. According to a recent survey by job-search site Snagajob, 44% of respondents who quit in the past year did so believing they would find a better opportunity elsewhere, up from 31% the year before.
