Article here. Tangential to MRM issues. It's a stereotype-buster. The notion that workplaces are made hostile for women by men seems a bit misplaced after reading this. But it is just one study. Excerpt:

'The phenomenon of women discriminating against other women in the workplace — particularly as they rise in seniority — has long been documented as the "queen bee syndrome." As women have increased their ranks in the workplace, most will admit to experiencing rude behavior and incivility.

Who is at fault for dishing out these mildly deviant behaviors? Has the syndrome grown more pervasive?

"Studies show women report more incivility experiences overall than men, but we wanted to find out who was targeting women with rude remarks," said Allison Gabriel, assistant professor of management and organizations in the University of Arizona's Eller College of Management. 

Gabriel and her co-authors set out to answer that question across three studies. Men and women who were employed full time answered questions about the incivility they experienced at work during the last month. The questions were about co-workers who put them down or were condescending, made demeaning or derogatory remarks, ignored them in a meeting or addressed them in unprofessional terms. Each set of questions was answered twice, once for male co-workers and once for female co-workers.'
