This study focuses on organisational citizenship behaviours, a relatively recent concept in organisational behaviour research. These behaviours are defined as "discretionary behaviours that are not directly and explicitly recognised by the formal reward system, but whose accumulation contributes to the efficient and effective functioning of the organisation". The aim of this work is to understand the influence of job satisfaction factors (intrinsic and extrinsic) on organisational citizenship behaviours oriented towards the organisation and the individual, but also the weight of these factors on these behaviours. The study was conducted on 116 female employees in various public and private organisations in Haiti. The results showed that intrinsic satisfaction is a very good predictor of organisational citizenship behaviour. It influences organisational citizenship behaviour towards the organisation and also towards the individual; extrinsic satisfaction influences organisational citizenship behaviour towards the organisation only.
