In Zimbabwe, as in any other country, there is a realisation that SMEs are innovative, flexible and require low startup capital. There is an increased interest in pursuing SMEs as a poverty reduction strategy and as a roadmap to higher living standards. SMEs in Zimbabwe are divided into two sectors, namely the service and the manufacturing sector. SME manufacturers encompass almost every facet of the local economy, such as food processing, toiletry production, the garment, leather and rubber industry, metal fabrication, furniture manufacturing, construction and art. Most research that has been done on the influence of employee perception of equity (EPE), organisational citizenship behaviour (OCB) on organisational commitment (OC) and turnover intention (ITS) has been on large organisations and little attention has been paid to SMEs. Studies on employee perception of equity and organisational citizenship behaviour has not filtered down to SMEs in developing countries. The primary objective of the study is to investigate the influence of OCB, EPE and OC on ITS in Zimbabwe’s SME sector. It also sought to ascertain the kind of relationships between OCB and OC, EPE with OC, OCB with ITS, EPE with ITS and finally OC with ITS. This study sought to determine whether there are any group differences with regard to SMEs employees perceptions on OCB, EPE, OC and ITS according to gender, age and industry type. A quantitative research method was used. Structured questionnaires were distributed to SMEs in five major cities. The data were collected from SME employees. The findings of this study show that there is a significantly positive influence of OCB on OC in the Zimbabwean SMEs. There is a significant strong positive influence of EPE on OC. There is also significant positive relationship between employees’ OCBs and their OC in Zimbabwe’s SME sector. There is a strong positive significant relationship of EPE with ITS and there is a strong positive relationship between employees OCBs and employees’ ITS in Zimbabwean SMEs. Finally, the results reveal that gender, marital status and industry type of the respondent influence OCBs, EPE, OC and their ITS in the Zimbabwean SMEs. Given that today’s business environments for SMEs are characterised by high levels of competition, lack of finance and uncertainty, it is recommended that SME managers should adopt good and proper management styles so that they can make good decisions. Scanning the environment is also necessary for competitive advantage not only for SMEs but also for large firms.
