<p>Volunteering is increasingly recognized as a key contributor to personal and societal well-being. This study examines its impact on well-being indicators among working individuals in Abu Dhabi, focusing on job satisfaction, work-life balance, mental health, social relations, and happiness. Using data from a large-scale survey, a path analysis explored the direct and indirect effects of volunteering on well-being. The study analysed volunteering frequency alongside subjective health, job satisfaction, income satisfaction, and mental health. Bio-demographic variations in volunteering and its effects were assessed across gender, marital status, education, living region, nationality, household headship, and age. Volunteering was significantly associated with higher job satisfaction, better subjective health, and greater happiness. Mental health and social relations played crucial roles in shaping volunteering behaviour, reinforcing its psychological and social benefits. Work-life balance influenced both well-being and volunteer engagement. Demographic differences indicated that age, education, region, nationality, and household headship shape volunteering patterns, underscoring the need for targeted policies. Volunteering enhances workforce well-being and supports workplace satisfaction. Policies promoting volunteerism in workplaces can foster a healthier, more engaged workforce, emphasizing social engagement as a vital mechanism for well-being improvement.</p>
