This is a book about the past, present and future of personality at work. It begins by introducing the principal concepts of current personality theory. A concerted effort is made to communicate the sense of coherence that exists among the components of personality such as needs, traits, social cognition, and emotions. The 'Five Factor Model' of traits is described. This work also gives an overview of the techniques used to evaluate personality and is a useful guide to personality research with suggestions on how it can be integrated into organizational research.
