This book is the fifth volume of the UNESCO-UNEVOC Book Series “Current Developments in Technical and Vocational Education and Training: Issues, Concerns and Prospects”. It brings together international theory and empirical research that deals with continuity and change of identity formation processes at work under conditions of modern working processes and labour market flexibility. Modern work processes in manufacturing and service organisations increasingly rely upon responsible and competent employees who are willing and able to engage in the tasks that their job requires and in continuous learning. This book connects the debates about skills formation, human resources development and the work commitment and professional orientations of individuals.
