This study investigates the multiple mediating roles of work engagement and work commitment in the job crafting-job satisfaction relationship. The participants of the survey were 247 electrical/electronic technology education lecturers in Nigeria Universities. We applied bivariate correlation, regression and path analysis via 5000 re-samples bias corrected (BC) bootstrap method, and confirmatory factor analysis for data analyses. The findings showed that job crafting has positive significant prediction of work engagement, work commitment, and job satisfaction. We also found that work engagement and work commitment has positive significant prediction of job satisfaction. The path analytical results revealed that work engagement and work commitment has full multiple mediation on the job crafting-satisfaction relationship. In the same vein, work engagement partially mediated job crafting and work commitment relationship. Similarly, we found that work commitment partially mediated the relationship between work engagement and job satisfaction.
Research has demonstrated that job complexity moderates the validity of general mental ability (GMA), the relationship between personality and job satisfaction, and the relationship between GMA and job satisfaction. However, no published research has investigated whether job complexity moderates the criterion validity of the Five-Factor Model (FFM) of personality for predicting job performance. This paper reports a meta-analytic examination of the moderator effects of job complexity on the criterion validity of the FFM of personality as assessed with forced-choice inventories. In accordance with the hypotheses, the results showed that job complexity moderates negatively the validity of conscientiousness and emotional stability and that it moderates positively the validity of openness. The implications for personnel selection research and practice are discussed.
Organizations face a progressively ageing workforce and jobs with direct customer contact are growing, creating challenging issues from a human resource management perspective. Drawing on socioemotional selectivity theory and lifespan development findings, this study focuses on the research gap in the service sector with regard to age, emotional labour, and associated positive and negative outcomes. Analyses using data from 444 service employees in Germany revealed age is negatively directly related to exhaustion and cynicism, and positively directly related to professional efficacy, as well as positively directly linked to engagement. Additionally, age predicts less burnout and more engagement indirectly through the use of the emotion regulation strategies surface acting and anticipative deep acting. This provides evidence against the general deficit hypothesis of age, which assumes a decline of employee skills and abilities with age. We find no evidence that older workers are worse than younger workers, with older workers using positive emotion regulation strategies, being more engaged and less burnt out.
