Maslow Theory: Abraham H. Maslow, an American psychologist has developed a classification of human needs which is known as ‘Hierarchy of Needs’. Needs are those desires, wants or urges of individuals which influence their behavior. 

Types of Needs:

Physiological Needs : These are the basic needs which a person is required to satisfy first of all in order to survive in life. These include the need for air. water, food, sleep, sex etc. As these needs are concerned with the sheer survival, they are at the base in the hierarchy of needs. An organisation can satisfy the physiological needs of its employees by offering good salary and comfortable working conditions.

Safety and Security Needs : These needs arise after the satisfaction of physiological needs. These includes physical safety against danger and economic security against old age, sickness etc. An employer can satisfy safety needs of his employees by offering job security, pension, gratuity, housing etc.

Social and Affiliation Needs : These are related to the natural desire to socialise or interact with others. The person needs love, affection, a sense of belonging, association, friendship with others. Once the people get their physiological and safety needs satisfied, the affiliation needs become more active.

Ego Needs : Ego needs include factors like self respect, autonomy status, recognition and attention from others. Organisation can satisfy these needs by offering challenging jobs, recognizing good performance, providing good job titles etc.

Self Actualization Needs : Self actualization needs refers to need to grow and self fulfillment. These needs arise after the satisfaction of all previous needs i.e., physiological, safety, social, ego needs. 

For example, A manager may provide opportunities for continuous learning, encourage creativity, grant independence and allow risk taking to help employees satisfy their self actualization needs.
