Due to societal, economic, and technological developments, organisations are faced with the pressure of increasing knowledge and the need for innovation. As a result, employees are expected to adapt to new situations and develop the necessary skills to complete tasks. This book aims to reflect the growing interest in informal learning in the workplace by integrating the work of scholars who approach the topic from different angles and methodologies, drawing on a range of theoretical and empirical studies. Providing state-of-the-art research, it outlines the starting points for future research and draws on the benefits and implications for those fostering informal learning at work.
