Hirsh's research is in the areas of organizations, inequality, and the law. Much of her work focuses on employment discrimination and the impact of antidiscrimination laws and corporate diversity policies on gender, race, and ethnic inequality in the workplace. Current projects include a study of the impact of employment discrimination lawsuits on changes in sex and race inequality in the workplace; a qualitative account of the factors that lead workers to file employment discrimination lawsuits based on interviews with plaintiffs in recent high-profile lawsuits; an analysis of the impact of corporate diversity policies on levels of workplace sex and race inequality and discrimination disputes at work; and a study of caregiver discrimination cases in Canada.
