The third edition of Workers' Compensation Law continues to feature the book's unique blend of theory and practice informed by the Carnegie Foundation's research on educating lawyers in a manner unparalleled in other law school texts on the subject. Additionally, the new edition fleshes out the concepts of permanent partial disability and permanent impairment, two unstable yet critical ideas in workers' compensation law, and examines the volatility surrounding the question of which workers qualify as "employees" under workers' compensation.
