Understanding Procrastination at Work focuses primarily on procrastination in the workplace, and offers a synthetic and comprehensive review of major theoretical concepts and empirical findings on general procrastination and its specific manifestations, causes, and consequences in the workplace. Building on theoretical insights and empirical research, the monograph proposes and empirically verifies an expanded conceptual framework that integrates individual and work-related factors that contribute to work procrastination and mechanisms explaining this phenomenon. It sits at the intersection of two disciplines, integrating psychological and management knowledge so that a wider audience may benefit from its content. It thus sheds more light on sources and explanatory mechanisms underlying procrastination as a universal behavior in the work setting, with meaningful implications for individuals and organizations alike. Overall, the monograph can serve as a contemporary compendium of knowledge that enables the scientific community and organizational practitioners to better understand procrastination behavior and its implications in professional settings. From the theoretical and empirical perspectives, the monograph provides practical cues to develop prevention and intervention strategies to effectively address and manage procrastination and enhance employee productivity in the organization.
