Organisational effectiveness is fundamental for sustainability and profitability. Effectiveness is measured observing the degree of profit, the reduction of the costs, the production quantity, efficiency and organisational citizenship behaviour (OCB). OCB is the willingness of an employee to perform tasks which are not officially and directly required by the employer, thus do not have any official and direct recompense from the contractual relations. This discretionary behaviour is always related to an enhancement perceived by the organisation. The review covers the last three decades of research and development in the organisational citizenship behaviour literature and has a special focus on literature from 2010 to 2019. Research led to consider these main outcomes of OCB namely compliance, altruism, organisational justice related to a fair environment workplace, perceived organisational support (POS) related and enhanced by a higher level of collectivism, power distance and uncertainty avoidance; procedural justice (PJ); transformational leadership (TSL) and the psychological contract (PC). This research would assist academicians, corporates and the general public understands the concept by the critical analysis conducted.
