NYU's Samuel Estreicher, Boston University's Michael Harper, and distinguished practitioner and NYU and Michigan Law adjunct professor Zachary Fasman have produced a new edition of this employment law casebook. The book incorporates the work of the Restatement of Employment, for which Estreicher and Harper were reporters. The authors' focus is the field as practiced, aiming at both theoretical insight and practical approaches to advising clients on cutting-edge issues. Extensive notes and questions introduce new legislative and judicial development throughout. Administrative developments, such as those involving the FLSA and the definition of regulated employment relationships, are also covered. A revised chapter on workplace injuries features the Supreme Court ruling refusing to stay injunctions against the OSHA temporary emergency rule on mandatory COVID-19 testing.
