Abraham Maslow's theory of human motivation enjoys undeniable popularity, but it is very often interpreted in a simplistic and erroneous way. Its original version suggests that our motivations are realized in a progressive order, in a hierarchical fashion, according to five typologies of needs. In a professional context, Maslow's pyramid can become a motivational tool both for managers seeking to understand their team members and improve their well-being, and for employees themselves. What are the 5 basic needs according to Abraham Maslow? Abraham Maslow's theory defines needs as physiological, security, affiliation, recognition and self-actualization. We begin with the physiological needs and continue in the order mentioned, which is the order of importance they have.The purpose of this manuscript is to introduce Abraham Maslow, detail the 5-level pyramid, the 8-level pyramid and give a life review application to the world of work.
