I strongly suspect this is a DoL methodology problem. Can we really believe that the same company that puts huge effort into retaining women through its maternity policies (5 months maternity leave with full pay [paternity is 7 weeks] and a $500 stipend for takeout meals after a baby's born, among other things) has a conspiracy reaching the highest levels to short change women, such that its legal department refuses to comply with court orders to hand over data in order to hide its crimes?
