A competent employee in private and public sectors will surely heighten the functioning of its organisation, which in the long run affects the whole organisational outcomes. Unlike profit-making firms, public sector employees such as those at public university librarians are complacent due to their customarily non competitive environment, availability of adequate funding and complying to their parent organisation’s customised strategies.Albeit the current academia restructuring, federal funds are becoming scarce, resources are fixed and operational costs have elevated significantly.To survive the changes and sustain competitive advantage despite the aforementioned challenges, public universities supporting units such as libraries must re-strategies their resources and re-tool its workforce asset accordingly. This paper reviews multi-constructs antecedents towards achieving employee performance among public university librarians namely the mediating effect of entrepreneurial orientation between entrepreneurial competencies and market orientation and also IT infrastructure capabilities to moderate the aforementioned constructs. The underpinning theories of these constructs are based on the Resource Based View and Theory of Planned Behaviour.
