Using a sample of 178,087 individuals employed in 315 occupations, the results indicate that strong occupations (operationalized as having high task significance) had advantageous effects on occupational satisfaction, tenure, and turnover intentions, and these effects were partially mediated by personality heterogeneity. Task significance had a negative effect on personality heterogeneity, and personality heterogeneity led to less favorable attitudes and behaviors. The occupational autonomy
