If there really is a “special place in hell for women who don’t help each other,” lots of women may sadly be headed there.

That’s according to a new study out of the University of Arizona, which found significant incidences of women-on-women rudeness at work.

Allison Gabriel, assistant professor of management, and her co-authors asked 1,440 full-time employed men and women about whether they felt demeaned, ignored or addressed unprofessionally during their previous month of work.

“We found . . . women [in the workplace] are ruder to each other than they are to men, or than men are to women,” Gabriel says in a press release.

Research also suggested that women with more dominant personalities were more likely to be targeted by their female counterparts.
