Abstract
Few empirical studies exist on the mediating role of occupational burnout on the relationship between job
demand and job involvement among employees in construction and manufacturing industries. Using a cross-sectional-survey involving 360 employees (male=212; female=148) whose ages ranged between 17 and 54 years (mean=28.01; SD=7.31) were randomly selected. The participants were selected using purposeful and simple random sampling techniques. The instrument for data collections were perceived job demand scale (α= .73), occupational burnout scale (α= .70) consisting of four dimensions (emotional exhaustion, reduced personal accomplishment, cynicism and interpersonal strain) and job involvement scale (α= .78). Five hypotheses were formulated and tested using multiple regression and Sobel test analyses. The results revealed that occupational burnout significantly increased with job demand (β= 0.31, p <0.01). Also, reduced personal accomplishment (β= 0.37, p <0.01), cynicism (β= 0.16, p <0.01) and interpersonal strain (β= 0.16, p <0.01) significantly increased with job demand. On the contrary, job demand did not significantly predict emotional exhaustion while job demand negatively predicted job involvement (β= -0.22, p <0.01). Lastly, the mediation analysis showed that occupational burnout significantly mediated the relationship between job demand and job involvement (β= -0.40, p <0.01). However, it was indicated that only reduced personal accomplishment (Z=-4.72, p <0.01) and interpersonal strain (Z= -2.45, p <0.05) significantly mediated the relationship between job demand and job involvement. Conclusively, the results of the
study revealed that job demand positively predicted occupational burnout and its dimensions, but negatively predicted job involvement, while dimensions of occupational burnout partially mediated the relationship between job demand and job involvement. Therefore, management of construction and manufacturing industries should take cognisance of job demand and occupational burnout in order to enhance employees’ level of job involvement.
