This book summarizes the state of our knowledge on the effects of men in women's professions - effects on the men, on their views of masculinity, on the occupations and on the women they work with. Do men get preferential treatment in these positions? Do they receive higher salaries? Or are they treated the same as their women colleagues? Through a series of statistical and demographic analyses, as well as case studies of men in professions such as teaching, secretarial work, care-giving and stripping, the contributors give a glimpse of the role of these men in bolstering or undermining the gendered assumptions of occupational sex segregation in the workplace.
