Disability and Equity at Work (Jody Heymann, Michael Ashley Stein & Gonzalo Moreno eds., Oxford Univ. Press 2014).
Abstract: "Despite international and national guarantees of equal rights, there remains a great deal to be done to achieve global employment equality for individuals with disabilities. In OECD countries, the employment rate of persons with disabilities was just over 40%, compared to 75% for persons without a disability; in many low- and middle-income countries, the employment rates are even lower."
