Organisational Behaviour (OB), is the study of human behaviour in the workplace, specifically the interaction between people and the organisation, with the goal of better understanding and predicting human behaviour in the workplace. Management is a vast business field and as a result, the OB course covers a wide range of topics, including individual and group behaviour at work, as well as organisational processes such as communication in the workplace, conflict management and negotiation strategies. Since a single person cannot be an expert in all aspects of management, studying OB will help our readers with understanding and predicting organisational life. It also aids in the comprehension of the nature and actions of individuals inside an organisation. In order to encourage employees and preserve interrelationships inside an organisation, OB is extremely important and necessary. In particular, the objectives of OB are explaining human behaviour, predicting human behaviour and exert influence over it. Managers must be able to explain why some employees engage in certain behaviours while others do not, predict how employees will respond to particular actions and decisions and exert influence on their employees' actions and decisions. This book, written by Ummi Naiemah Saraih, Khairun Nissa Khairudin and Irza Hanie Abu Samah, is a comprehensive exploration of everything related in a variety of areas that has been authored by these OB experts.
