The correlation between employee mental health and job performance for sustainable human resource management

This study examines the relationship between employee psychological health and job performance within sustainable human resource management frameworks, focusing on frontline workers from multi-province oil companies. Through a combination of theoretical and empirical analysis, it was found that four demographic factors, age, education level, income, and job type, have a significant impact on mental health ( p < 0.05). The regression results showed a positive correlation between mental health and job performance (adjusted R 2 = 0.374, β = 0.586, p < 0.05), and all three dimensions of mental health were positively correlated with job outcomes to varying degrees. The research findings emphasize that employees’ mental health is a key determinant of job performance, indicating that sustainable human resource management practices should be incorporated into mental health support mechanisms. For energy sector organizations and other high-stress industries, these results provide empirical justification for investing in workplace mental health initiatives. The study contributes to academic literature and practical human resource management by demonstrating how psychological factors directly influence organizational performance metrics within sustainability-oriented business models.
