What motivational theory is Frederick Herzberg known for researching?

Frederick Herzberg is widely recognized for his research on the Two-Factor Theory, which distinguishes between factors that cause job satisfaction and those that lead to job dissatisfaction. According to his theory, certain elements in the workplace, referred to as hygiene factors—such as salary, company policies, and working conditions—do not necessarily motivate employees but can lead to dissatisfaction if they are inadequate. Conversely, motivators, like recognition, achievement, and opportunities for growth, are the factors that truly enhance employee satisfaction and motivation. This theory is significant because it offers insight into how organizational practices can be structured to foster higher levels of employee engagement and satisfaction, highlighting the importance of addressing both hygiene factors and motivators in the workplace.
