This study investigates the differences in three aspects of job satisfaction – total pay, promotion prospects, and respect received from one's supervisor – between male heterosexual and gay employees in Athens, Greece. Gay employees are found to be less satisfied according to all job satisfaction measures. Affect Theory proposes that the extent to which one values a given facet of work moderates how dissatisfied one becomes when one's expectations are not met. Furthermore, the data enable us to estimate that gay employees' job satisfaction is not associated more (as compared to heterosexuals' job satisfaction) with adverse mental health symptoms. This finding is crucial given the rising interest between job satisfaction and life satisfaction. Finally, wage gaps against gay employees are found after accounting for basic asymmetries. Interestingly, however, the wage gaps grow for very dissatisfied employees and shrink for very satisfied employees. As long as, the general patterns in Greece suggest that homosexual employees face labour market discrimination, gay employees will report being less satisfied at work. Actually, in this study, job satisfaction is associated with wage inequality. This research initiates efforts to compare job satisfaction based on sexual orientation.
