The coverage has been extended to include Organisational Behaviour, with new chapters on Power, Politics and Conflict; Organisational Structure and Design; Organisational Culture; Organisational Change and Development; Human Resource Practices (Performance Management, Rewards, Selection); and Hazards at Work (Ergonomic issues). The original chapters have been thoroughly updated and new material has been added on Intelligence and Testing; Job Design; Communication; Training; Creativity; Decision Styles; Job Satisfaction and Organisational Commitment; Teambuilding; Inter-Group Behaviour; Leadership; International Issues; and Occupational Stress. This will be an essential textbook for courses in business psychology and organisational behaviour.
