Women need to justify requests for pay increases and other resources more than men, a study reports (H. R. Bowles and L. Babcock Psychol. Women Quart. http://doi.org/j99; 2013). The authors asked more than 500 university graduates with some work experience to evaluate videos of men or women asking supervisors for resources. Women's requests generally met with disapproval. Co-author Hannah Bowles, who studies gender and leadership at Harvard University in Cambridge, Massachusetts, says that mentioning a mentor or adviser in negotiations may help women. “Use a lot of 'we' language and signal that you have these positive working relationships,” she says.
