This study analysesthe effect of transformational leadership on turnover intention, incorporating happiness management andwork-related stress as mediating variables. Additionally, it explores potential differences between Mexico’spublic and private sectors. A quantitative, non-experimental, and cross-sectional design was employed, using astructured questionnaire administered to a sample of 414 employees from various educational, governmental,and corporate institutions. Data were analysed through Covariance-Based Structural Equation Modelling (CBSEM)and multigroup analysis. The results indicate that transformational leadership positively influenceshappiness management, reducing stress and turnover intention. Although work-related stress increased turnoverintention, its mediating effect was not statistically significant. Sectoral differences were also observed: in theprivate sector, transformational leadership acted as a buffer against stress, whereas in the public sector,happiness management played a stronger role in reducing turnover. The proposed model contributes to theadvancement of Social Exchange Theory by incorporating emotional mechanisms as key explanatory factors foremployee retention. The findings offer valuable insights for developing human-centred organisational policiestailored to sector-specific dynamics and aligned with the Sustainable Development Goals related to decentwork and emotional wellbeing.
