Final answer:
Research has suggested that the work-content factor is the most strongly predictive factor of overall job satisfaction, whereas pay level has only a weak correlation with job satisfaction.
Step-by-step explanation:
Research has suggested that the work-content factor, which includes variety, difficulty level, and role clarity of the job, is the most strongly predictive factor of overall job satisfaction (Saari & Judge, 2004). In contrast, there is only a weak correlation between pay level and job satisfaction (Judge, Piccolo, Podsakoff, Shaw, & Rich, 2010). Judge et al. (2010) suggest that individuals adjust or adapt to higher pay levels: Higher pay no longer provides the satisfaction the individual may have initially felt when their salary increased.
