Based on the social exchange theory, the current study aimed to develop and test a conceptual model that integrates the relationships among internal marketing dimensions (i.e., supportive and participative leadership, training and development, information and communication, and selection and appointment) and job satisfaction in the banking sector of Saudi Arabia, particularly during the COVID-19 pandemic. We collected data from 329 employees working in different private and public banks in Riyadh, Saudi Arabia. Overall, the findings confirmed the significant and positive effects of supportive and participative leadership, training and development, information and communication, and selection and appointment on employees’ job satisfaction. The current research contributes to the understanding of the broad role played by internal marketing practices in maintaining the job satisfaction of banking sector employees, during and possibly after the COVID-19 pandemic.
