Book excerpt: An Introduction to Labor Law is a useful and course-tested primer that explains the basic principles of the federal law regulating the relationship of employers to labor unions. In this updated third edition, which features a new introduction, Michael Evan Gold discusses the law that applies to union organizing and representation elections, the duty to bargain in good faith, economic weapons such as strikes and lockouts, and the enforcement of collective bargaining agreements. Gold describes the structure and functions of the National Labor Relations Board and of the federal courts in regard to labor cases and also presents a number of legal issues presently in contention between labor and management.
