Maslow's Need Hierarchy Theory
Maslow's hierarchy of needs is a model for the various needs of humanity, with important implications for behavior in the workplace. When Maslow's hierarchy of needs is applied to work situations, it implies that managers have the responsibility for the company and employees.Failure to do so would theoretically increase employee frustration and could result in poorer performance, lower job satisfaction, and increased withdrawal from the organization.
Maslow’s theory classifies human needs as lower-order needs and higher-order needs. It states that a satisfied need is not a motivator of behavior. It states that five needs exist in a hierarchy and that a need does not become activated until the next-lower-level need is already satisfied. People are expected to advance step by step up the hierarchy in their attempt to satisfy the lowest-level need that is currently unfulfilled.
Our most basic needs are inborn, having evolved over tens of thousands of years. Only when the lower order needs of physical and emotional well-being are satisfied are we concerned with the higher order needs of influence and personal development if the things that satisfy our lower order needs are swept away, we are no longer concerned about the maintenance of our higher order needs. Maslow's Hierarchy of Needs is an excellent model for understanding human motivation, but it is a broad concept.
