Editorial verdict
Methodologically adequate but contextually narrow — the psychological contract's dominance over organisational justice in predicting OCB is a legitimate finding, but single-institution convenience sampling and cross-sectional design limit generalisability; treat the directional finding as hypothesis-generating, not confirmatory.
Executive summary
This study addresses the relative predictive strength of the psychological contract versus organisational justice on organisational citizenship behaviour (OCB) among academic staff in a South African higher education institution. The authors argue that while organisational justice has historically been positioned as a primary driver of OCB, the psychological contract — defined as employees' beliefs about mutual obligations with their employer — may exert a stronger and more direct influence on discretionary work behaviour. Using a quantitative cross-sectional survey design with 340 academic employees and analysed via structural equation modelling (SEM) and the PROCESS macro, the study finds that organisational justice did not significantly predict OCB (β = −0.015, p = 0.739) when the psychological contract was included, whereas the psychological contract demonstrated a significant positive effect (β = 0.247, p < 0.001), with the combined regression model explaining approximately 26% of OCB variance. The findings are interpreted through Social Exchange Theory and Equity Theory. The authors conclude that in resource-constrained South African universities, fulfilling implicit institutional promises may matter more to academic staff's discretionary engagement than formal fairness perceptions, with implications for how university leaders manage staff relationships in post-pandemic and transformation contexts.
Key insights
- 1Organisational justice did not significantly predict OCB when the psychological contract was simultaneously included in the model, challenging the conventional primacy of fairness perceptions as OCB drivers in the one South African higher education institution studied.
- 2The psychological contract emerged as a significant positive predictor of OCB (β = 0.247, p < 0.001), with the combined model explaining approximately 26% of OCB variance, suggesting that perceived fulfilment of mutual obligations is a more proximal driver of discretionary behaviour than fairness perceptions.
- 3In the South African higher education context, resource constraints, post-pandemic pressures and transformation demands may amplify the relative importance of psychological contract fulfilment over procedural or distributive fairness as a motivator of extra-role behaviour.
Practical takeaways
- University managers who focus exclusively on equitable policies and fair procedures may find these insufficient to sustain academic staff's voluntary behaviours; the perceived consistency between institutional promises and actual delivery on matters such as career development, recognition and workload management appears to be a stronger lever for encouraging OCB.
- Transparent communication about institutional commitments and follow-through on informal expectations — particularly around professional support and career progression — are recommended by the authors to encourage higher levels of discretionary staff engagement in this study's context.
Frameworks mentioned
Social Exchange Theory
Theoretical framework developed by Blau (1964) proposing that workplace relationships are governed by norms of reciprocity; used in this study to explain how perceived fulfilment of obligations motivates positive discretionary behaviours.
Equity Theory
Framework developed by Adams (1963) positing that employees evaluate fairness by comparing their input-outcome ratios with those of others; applied here to contextualise the role of organisational justice perceptions in motivating OCB.
