Final answer:
Job satisfaction positively affects employee performance and customer service according to the service profit chain model. Autonomy is the strongest predictor of overall job satisfaction.
Step-by-step explanation:
The service profit chain model suggests that job satisfaction has a strong influence on multiple aspects of work life and organizational outcomes. Specifically, job satisfaction is proposed to have a positive effect on employee performance and customer service. This is because job satisfaction can lead to behaviors that are beneficial to the organization, such as organizational citizenship, where employees go above and beyond in their roles to support the company's goals. High job satisfaction can reduce negative behaviors such as withdrawal actions, which include leaving the job or being absent without legitimate reasons. Moreover, job satisfaction has been connected to the general satisfaction with life, highlighting its importance beyond the workplace. While financial rewards, personality, and work content do influence job satisfaction, autonomy — the control and input employees have over their work — is the most strongly predictive factor of overall job satisfaction.
