Which of the following is NOT one of the three theories of job satisfaction?

The three primary theories of job satisfaction typically include Affectivity, Herzberg's Two-Factor Theory, and Organizational Justice. Therefore, identifying Equity Theory as the one that does not fall under the category of job satisfaction theories is accurate.

Affectivity relates to individuals' emotional responses and how they influence their overall satisfaction with their job. Herzberg's Two-Factor Theory distinguishes between factors that lead to job satisfaction (motivators) and those that lead to job dissatisfaction (hygiene factors), providing a framework for understanding what makes employees happy or unhappy at work. Organizational Justice examines how fairness in the workplace impacts employee morale and job satisfaction.

In contrast, Equity Theory focuses on the perceived fairness of work outcomes compared to others, which, while it may indirectly relate to job satisfaction, does not primarily address it as a central theory of job satisfaction. Thus, placing Equity Theory outside the main three theories of job satisfaction is justified.
