The extant research findings have identified lacunas (i.e. gaps, unresolved issues, and black box) in the High-Performance Work System (HPWS)-Performance relationship and suggested usage of a mechanism (mediator) that can close up the identified lacunas. Thus, this study investigates whether employee creativity can play a mediating role in the relationship between HPWS and firm non-financial performance. The sample size of the study is 518, and respondents were selected through stratified sampling technique. Data were collected from the sampled 518 managers in Nigerian firms. Partial Least Squares (PLS) algorithm and bootstrapping techniques were used for data analysis. The result indicates that employee creativity competitively/partially mediates the relationship between HPWS and non-financial performance. Employee creativity represents an appropriate mechanism to explain the relationship between HPWS and non-financial performance. Hence, the positive indirect effect via the mediator variable (employee creativity) reveals the ‘true’ relationship between HPWS and non-financial performance. This result implies that HPWS may not necessarily enhance non-financial performance. Ill-configured HPWS could jeopardize non-financial performance, but HPWS that stimulates employee creativity would enhance non-financial performance. Lastly, the implications, limitations and suggestions for future research are discussed.

This study assessed the impact of ethical leadership on employee performance in the public sector using leader-member exchange as a mediator. Data for this quantitative study was gathered using a structured questionnaire administered to Nigerian federal public officials in some selected ministries. A conceptual model was drawn and put to the test using the PLS-SEM. Based on the results, all hypotheses were significant at p < 0.001. More importantly, ethical leadership positively and significantly impacts leader-member exchange and employee productivity. More so, leader-member exchange mediates the relationship between ethical leadership and employee performance. This study’s findings improve on earlier studies on ethical leadership and leader-member exchange relationships. Also, it suggests the importance of leaders’ moral behaviour and their relationship with subordinates in the workplace, by imbibing workplace ethics. This study has added to the continuing discussion on ethical leadership and its implications in the public sector in a developing nation like Nigeria.
