Which theory emphasizes the impact of emotional reactions triggered by workplace events on employee performance?

The theory that emphasizes the impact of emotional reactions triggered by workplace events on employee performance is known as Affective Events Theory (AET). This theory posits that employees' emotional experiences at work significantly influence their job satisfaction, motivation, and overall performance. According to AET, specific workplace events can evoke emotional responses that lead to different behaviors in employees. For example, positive events might enhance engagement and productivity, while negative experiences could lead to frustration and decreased performance.

Affective Events Theory highlights the importance of emotional aspects in the workplace, suggesting that understanding and managing these emotions can lead to better employee outcomes and organizational effectiveness. This perspective encourages organizations to create a work environment that minimizes negative emotional triggers and enhances positive experiences.

The other theories, while significant in their own right, do not specifically focus on the emotional responses to workplace events. Cognitive dissonance addresses the discomfort arising from holding conflicting beliefs or behaviors; Need for achievement theory emphasizes individuals' drive for success; and the Five-stage theory of group development outlines stages that teams go through without concentrating on emotional reactions.
