Research indicates that one factor contributing to the income gap between men and women is that women don’t negotiate their starting salaries. A recent study revealed that when a salary was advertised as fixed, women took it without a fight, whereas men were more likely to raise a stink. It’s not that we can’t wangle bump: Women were three times more likely to apply for jobs when the salary was advertised as negotiable and to negotiate on their own behalf. Don’t sell yourself short!
