This study examines the relationship between age and job satisfaction using data from the 2015 Canadian Work, Stress, and Health Study (CANWSH), a national sample of Canadian workers. The extent to which job satisfaction can be attributed to age versus factors such as more favorable job characteristics or enhanced general well-being remains relatively unexplored within the Canadian context. The theoretical basis for anticipating that with age individuals are more likely to experience positive emotions stems from socioemotional selectively theory. Using multivariate logistic regression models, we estimate the influence of measures of general life satisfaction on job satisfaction relative to other factors such as income and job characteristics at different age periods. Findings indicate that levels of job satisfaction are higher among older workers, overall life satisfaction increases the likelihood of higher job satisfaction among older women, and that job control is associated with increases the likelihood of higher job satisfaction for younger workers. Given that the gap between average retirement age and life expectancy has widened in Canada and worldwide, findings highlight the need to examine factors that may foreshortened the careers of more mature workers, particularly when levels of job satisfaction are relatively high.
