Peggy Drexler, an assistant professor of psychology in psychiatry at Weill Cornell Medical College, says that in her experience women tend to resent female bosses who adopt a brusque and assertive management style, even as they find it perfectly acceptable for male bosses, so they question and push back, answering authority with attitude. Dr. Drexler's article in the March 2 Review section about so-called queen bees in the workplace incorrectly attributed these observations to a 2007 Syracuse University study published in the Journal of Occupational and Organizational Psychology. In addition, the study found that both men and women were less satisfied with female managers who weren't empathetic. The article incorrectly implied that the study found that only women were critical of female bosses who weren't empathetic. Also, the name of the publication was incorrectly given as the Journal of Operational and Organizational Psychology.
