Work well-being as a key factor for better performance among young employees

The present study examines the relationship between work well-being and job performance among young employees (Gen Z and Millennials) in Spain. A PLS-SEM analysis of survey data from 412 workers was conducted to ascertain how four dimensions of well-being (job satisfaction, supervisor emotional accessibility, organisational respect, and impact on mental health/personal life) affect three performance facets (task, contextual and counterproductive behaviours). The findings of the study demonstrate that job satisfaction exerts a substantial influence on both task and contextual performance. Conversely, the detrimental effects on mental health and personal life are found to be associated with an escalation in counterproductive behaviours and a decline in contextual performance. It is interesting to note that supervisor emotional accessibility and organisational respect did not directly influence performance, suggesting that they may act as baseline expectations rather than motivators. The findings serve to refine social exchange theory and offer practical guidance, prioritising mental health protection and intrinsic job satisfaction to enhance young workers’ performance and well-being.
