At present, 80% of the employees are no longer engaged in their work and capable of performing, while 44% are experiencing work related stress and getting sick from working. A significant increase in time spent on interpretation at work trying to understand what managers and colleagues are saying has been observed too. This book offers a critical view on vocational inventory tests and the development of the work language and the use of it describing work identity.As well as a neurophilosophical perspective on self and work identity, this book provides a plausible neurophilosophical explanation for the negative impact of losing work identity on our work behavior, well-being, and success. Furthermore, the author introduces the innovative Work Identity Pro, the first work identity test to independently measure work identity.It will be of great interest to scholars and students of human resources management, organisation studies and organisational psychology. It will also be of interest to managers and those with an interest in work identity, behaviour and well-being.
