Abstract: South African organisations have to survive in an increasingly competitive and globalised environment. Many believe that South African organisations are ill prepared for these challenges, based on the fact that many organisations are plagued by low productivity, low levels of trust between employees and employers, as well as low levels of organisational commitment, effectiveness and efficiency. Solutions must be found for these problems and the present study offers one such solution. Organisational citizenship behaviour is essentially pro-social organisational behaviour that is characterised by going beyond what is expected in role requirements or role descriptions and is seen as a key driver of individual and organisational performance. Furthermore, an organisation’s ability to elicit organisational citizenship behaviour is believed to be a vital asset that is difficult for competitors to imitate and which provides the organisation with a competitive advantage. Having completed a literature study concerning possible antecedents of organisational citizenship behaviour, and taking into account various suggested future directions for organisational citizenship behaviour research, it was decided that the present study would focus on five variables: three variables that are characteristic of employees, and two that are characteristic of the management or leadership in the organisation. The primary goal of the present study was to design and conduct a scientific investigation that would attempt to determine the relationships between leader emotional intelligence, transformational leadership, trust, meaning intention to quit, and organisational citizenship behaviour, as well as to further determine the role that these five constructs play in influencing organisational citizenship behaviour. A study of the available literature was made to learn as much as possible about each of these six constructs and to determine what is known about the relationships that exist between them. The knowledge gained from the literature study was used to propose several hypotheses and a conceptual model explaining the relationships between these constructs. The relationships and the conceptual model were then empirically tested, using various (mostly confirmatory) statistical methods. This makes the present study confirmatory in nature.
