One of the subjects that receive much attention in current human resource management studies is job satisfaction. The influences of job satisfaction on businesses and government organizations have been demonstrated by empirical investigations. This research focuses on the job satisfaction of Indonesian diplomats. Given the nature of the work of diplomats who must periodically rotate between headquarters and mission offices abroad, as well as the promotion system currently taking place in the Indonesian Ministry of Foreign Affairs, this research observes how job rotation practices, perceptions of promotion opportunities, and perceived organizational support influence the satisfaction of the diplomats with their job. This research also investigates the mediation role of employee engagement on the relationship between the three independent variables and job satisfaction.
