PurposeSustainable development must address the challenge of ensuring decent work for all (SDG 8) and promoting good health and well-being (SDG 3). This study aims to assess the relationship between decent and meaningful work and their impact on work engagement and job satisfaction among adult workers. Decent work goes beyond mere employment, encompassing standards for a fulfilling life, including fair compensation and workplace security, while fostering personal development and social integration.
