This research examines the meaning, causes, and effects of happiness in the workplace in a government organisation, specifically within one of the Saudi Arabian Government’s Royal Commissions. It examines the impact of employee engagement, job satisfaction, and organizational commitment on happiness at work by adopting Fisher’s framework (2010). The data was collected using a simple random sampling approach, and a questionnaire survey was designed and distributed to employees working in this government organization. Three thousand people were targeted using the convenience approach, and the response rate was 23.5%. The demographic data analysis was conducted using a descriptive statistical approach, and the hypothesis was tested using correlation and regression analysis. The results reveal that workplace happiness depends mainly on organizational commitment; however, employee engagement and job satisfaction also contribute to the individual’s happiness at work.
