Herzberg's Two-Factor Theory, also known as the Motivation-Hygiene Theory, was developed by psychologist Frederick Herzberg in the 1950s and 1960s. This influential theory suggests that job satisfaction and job dissatisfaction are influenced by two different sets of factors: motivators and hygiene factors. The two-factor theory states that job satisfaction and dissatisfaction are caused by different factors that act independently of each other. It was developed by psychologist Frederick Herzberg, who identified motivators (intrinsic to the work) and hygiene factors (extrinsic to the work) as the two sets of factors. Herzberg’s Two-Factor Theory, also known as the Motivation-Hygiene Theory, is one of the most influential theories in the field of motivation and organizational behavior. Developed by psychologist Frederick Herzberg in the 1950s, this theory seeks to explain how different factors in the workplace impact employee motivation, satisfaction, and productivity. Herzberg proposed that job satisfaction and dissatisfaction are influenced by two distinct sets of factors: motivators and hygiene ... The two-factor theory laid important groundwork for subsequent motivation theories. It influenced the development of job characteristics model by Hackman and Oldham, which expanded on Herzberg’s ideas about what makes work meaningful.
