As per TOI, the report was released right before the start of the annual meeting of the World Economic Forum. 

The report highlighted that women (of all ages) are the worst hit by the rise of economic inequality, and in India, inequality has a 'female face'. In fact, the existing wage gap in India stands at 34%, and thus, when compared households where females are the sole earner are poorer.

The study also highlighted the prevalent practices of harassment against women in the workplace and when women are employed in unpaid work. Majority of women in the informal sector have no formal mechanism to report exploitative actions. In the case of unpaid work, the majority of men consider harshly criticizing women or beating them as a normal practice.

The report also highlighted that both social and economic factors hinder a woman from seeking paid work. Oxfam International Executive Director Winnie Byanyima said, 

While corporations and the super-rich enjoy low tax bills, millions of girls are denied a decent education and women are dying for lack of maternity care.
