The sustainable development of working students in tertiary education institutions is important for student retention and institutional success. As the number of working students is on the rise, it is imperative that the needs of working students are well-recognized to ensure academic satisfaction and engagement. As these students encompass the role of both an employee and a student, inter-role conflict is experienced when pressures from the workplace disrupt academic responsibilities and influence academic outcomes. Therefore, the aim of the present study was to examine the impact of type of employment (part-time employment and full-time employment) on university outcomes, namely academic satisfaction and academic engagement of working students. The study proposed that those working students in part-time employment would on average experience less work-school conflict, more academic satisfaction and more academic engagement than those working students in full-time employment. The study implemented a secondary crosssectional descriptive design, whereby secondary data was used. The study's sample consisted of working students (n = 482). Independent samples t-tests and mediation analyses were conducted to analyse the study's hypotheses. A significant difference was found between those working students who participated in part-time and full-time employment, in terms of their work-school conflict and academic satisfaction. However, no significant difference was found for the academic engagement outcome. The analyses revealed that work-school conflict mediated the relationship between type of employment and academic satisfaction, however mediation effects were not found between type of employment and academic engagement. The findings of the study have theoretical contributions and practical implications for university intuitions and researchers. Lastly, research contributions and suggestions for future research are presented.

Working while studying is a popular trend around the world and the number of nontraditional students are increasing. As a result of working and studying simultaneously, workschool conflict tends to occur. There is still some debate as to which characteristics across the personal and work domains most significantly influence work-school conflict. Similarly, the extent to which social support moderates the experience of work-school conflict is unclear. In this study, secondary data was used to examine a model of work characteristics consisting of job demand, job control and working hours, as well as personal characteristics which include marital status, gender and number of dependents. Further, the effect of social support, comprising of family support, co-worker support and supervisor support as a moderator in this work- and personal characteristics model was also explored. The respondents of this study (N = 367) were from either a South African or American context and the characteristics in both contexts were explored. The analysis revealed that the proposed work- and personal characteristics model is not significant; and social support does not moderate the relationship. Furthermore, this research study found that there are different significant predictors of workschool conflict across the two distinct contexts.

The cost of higher education is rapidly increasing on both a global scale (Creed, French & Hood, 2015), and in the local South African context (Calitz & Fourie, 2016). This rise in costs has seen a commensurate increase in the number of university students who work, largely as a means to fund the increasing cost of their higher education (Butler, 2007; Cinamon, 2016; Owen, Kavanagh & Dollard, 2018). These working students are frequently referred to as non-traditional students in the academic literature. The psychological experiences of non-traditional students who work is a pertinent and expanding area of interest for multiple stakeholders (Owen et al., 2018). These experiences can be classified through the constructs of Work-School Conflict (WSC) and Work-School Enrichment (WSE), which refer, respectively, to the negative and positive aspects of the work-school interface (Butler, 2007). The antecedents of WSC and WSE experiences amongst nontraditional working students have to date not received any empirical attention in the South African research literature. This study aims to address this gap by contributing to the national body of knowledge in this area. The measures used were secondary self-report survey data completed by post-graduate university students who are simultaneously engaged in paid work (N=330). Multiple regression analyses indicated that time demands, job demands and social support from work explained a significant proportion of WSC; whilst job-school congruence and social support within the work context were statistically significant predictors of WSE. Moderation analyses revealed that social support at work influenced the relationship between job demands and WSC, whilst employee role saliency significantly interacted with job-school congruence to influence WSE. The results of this study are aligned to international work-school research findings, which support the additive model of job characteristics as antecedents to WSC and WSE. These results also provide deeper insight into the less explored moderation effects of work resources and demands interacting to influence WSC and WSE. Theoretical, management and educational implications of these findings are considered in relation to the existing literature.

The growth of a country's economy is highly dependent on the levels of skills available in that country. South Africa has a stark shortage of skilled individuals due to an inadequate and failing education system (Horwitz, 2013). As a response to this problem the South African government actively incentivises organisations to develop the skillset of their employees in order to build a strong economy, improve job creation and promote social development (Department of Higher Education and Training, 2019). It is therefore important that all stakeholders involved yield a return on this investment. It is also a global phenomenon that an increasing number of fulltime employees are also engaging in formal further studies due to the rapid changes in the labour market. For example, advancements in technology have had a major impact on traditional business models and the roles, and skills needed. These employees are referred to as non-traditional students and are the subject of this study. Research shows that trying to manage both work and school simultaneously can cause psychological strain for non-traditional students (Adebayo et al., 2008). The psychosocial safety climate (PSC) is an emerging construct which refers to the shared perceptions regarding policies, practices and procedures designed to protect the psychological health of employees (Dollard et al., 2012). This study builds on existing research in the work - school interface by investigating its application within the South African context. Participants in this research (n=127), comprised of non-traditional students (n=40) and employees who are not engaged in further studies (n=87). Correlation analysis demonstrated that PSC had a positive relationship with work school facilitation (WSF) and a negative relationship with work school conflict (WSC). It was further confirmed that job control (JC) mediated the relationship between PSC and WSF and that PSC mediated the relationship between JC and WSF. These findings show that PSC is an antecedent to the work school interface in that it promotes the positive outcomes of studying while working (work school facilitation). It further demonstrates that PSC also reduces the negative outcomes (work school conflict). This study confirmed that the working environment plays a crucial role in the work school interface and introduces PSC as a construct South African organisations should be concerned with and make a priority, based on the resources it provides employees, more especially their non-traditional students. This study's findings will add to the existing body of research and provide practical insights for enhancing the PSC application within South African organisations who have non-traditional students.
