The Kitchen Chick sent me this fascinating article, on a new study which claims to show that the most significant pay gap is between men with traditional views on gender roles and *everybody else*, including men with non-traditional views. My first thought about how to explain this was that men with non-traditional views are more likely to be putting in substantial amounts of time on childcare– so they might work in lower-paid, more family-friendly work, or work fewer hours. But these possibilities have been ruled out: The authors have carefully compared people working in the same jobs, for the same hours and the same length of time. The explanations they suggest are that traditional men might be tougher salary negotiators, or that employers discriminate against those without traditional views. If the latter, then maybe there needs to be a new protected category for discrimination law? Other thoughts?
