In this chapter we have reviewed the basic motivation theories that have been developed to explain motivated behavior. Several theories view motivated behavior as attempts to satisfy needs. Based on this approach, managers would benefit from understanding what people need so that the actions of employees can be understood and managed. Other theories explain motivated behavior using the cognitive processes of employees. Employees respond to unfairness in their environment, they learn from the consequences of their actions and repeat the behaviors that lead to positive results, and they are motivated to exert effort if they see their actions will lead to outcomes that would get them desired rewards. None of these theories are complete on their own, but each theory provides us with a framework we can use to analyze, interpret, and manage employee behaviors in the workplace.
