Psychology is critical to the workplace. It helps managers at all levels of organizations select, support, motivate and train employees. It also helps businesses design products, build better workspaces and foster healthy behavior. Through their scientific research, psychologists are discovering new ways to increase productivity, identify training and development needs, and implement policies proven to attract and retain the best employees. By studying how people interact with technology and equipment, psychologists can help make these tools more user-friendly and prevent errors, whether we are using everyday products or life-critical technologies. Understanding psychology helps managers lead the team to great success. The middle level needs to lead the lower level but also work according to the guidelines issued by the top management. The current book brings together research to advance organizational science and practice on essential topics such as motivation, job satisfaction, leadership, compensation, organizational justice, communication, intra- and inter-team functioning, judgment and decision-making, and organizational behavior.
