The Moderating Role of Work–Life Integration in the Relationship Between Side-Hustles, Employee Commitment and Workplace Attachment

A recurring question in contemporary society is: How can one survive on a single income? Escalating socioeconomic challenges worldwide are pushing many households beyond their financial comfort zones. As a coping strategy, many individuals have adopted side hustles, income-generating activities pursued alongside full-time employment. However, a crucial question arises: do side hustles come at the expense of primary employment, particularly in terms of employee commitment and workplace loyalty? This study examined the moderating role of work–life integration in the relationship between side hustles, employee commitment, and workplace attachment. The unit of analysis consisted of academic and support staff at South African higher education institutions. Primary data were collected through a survey of a stratified random sample of 300 employees, and the data were analysed using structural equation modelling. The findings support that side hustles offer meaningful opportunities to enhance individual livelihoods by mitigating the impact of declining income levels. Moreover, the results indicate that flexible work arrangements are critical for employees engaged in hustle, as such flexibility strengthens organisational commitment and workplace attachment. The study recommends adopting a humanistic management approach that promotes boundaryless jobs, thereby fostering employee commitment and workplace attachment through an inclusive, supportive, and empowering work environment.
