What are practice theories? Where do they come from? What do they say? Do they offer something new to the study of work and organization? Practice theories are a set of conceptual tools and methodologies for investigating, analysing, and representing everyday practice. They develop the idea that phenomena such as knowledge, meaning, science, power, organized activity, sociality, and institutions are rooted in practice. The volume provides a rigorous yet accessible introduction to this emerging area of study. Recognizing that a unified theory of practice does not exist, the book surveys the main scholarly traditions that have,collectively, contributed to the practice turn in social and organization studies. Each chapter examines the main assumptions and concepts of these traditions, discussing their distinctive contribution to work and organization studies. The chapters are accompanied by a fully worked example of how thetheory can be applied to empirical research, making the text suitable for teaching purposes.The book will constitute a valuable resource for researchers and graduate students in organization studies and management, and scholars across disciplines who are interested to know more about the topic.
