Bachelor degree acquisition is increasingly common, with many enrolling in university programs in hopes of providing a stable financial foundation for later life. However, new university graduates are greatly outpacing careers which mandate a university education, resulting in many of them occupying positions lesser than their expectations, and/or positions which do not mandate a university degree. A sample of 500 Amazon Mechanical Turk workers completed a battery of previously validated scales, and self-reported subjective underemployment / perceived overqualification was examined alongside several personal, and organizational outcomes of interest. Collectively, subjective underemployment and perceived overqualification accounted for significant portions of the variance in three personal outcomes (self-esteem, well-being, and life satisfaction). Higher levels of underemployment and overqualification were associated with poorer personal (e.g., lower self-esteem) and organizational (e.g., fewer organizational citizenship behaviours) outcomes. Subjective underemployment and perceived overqualification were also associated with lower levels of affective organizational commitment and stronger turnover intentions. Together, the findings suggest that employers may greatly benefit from minimizing perceptions of underemployment or overqualification among their personnel.
