(Undated)  --  Women earn less than men, even in woman-dominated jobs.  A new study from the Institute for Women's Policy Research shows that in the 20 most common occupations for women, their median weekly earnings for full time work came out to less than those for men. 

For instance, female elementary and middle-school teachers took home an average of $937 dollars a week in 2013, while their male counterparts averaged $1,025.  In all jobs, the study showed the pay gap between men and women was nearly 18 percent.
