Turnover has been used as an organisational performance indicator since the early work of March and Simon (1958). These social scientists defined employee turnover intention as a reflection of an employee’s decision to participate and work in the organisation. More recently, Denvir and McMahon (1992:143) define labour turnover as “… the movement of people into and out of employment within an organization.”. These definitions suggest the turnover intention can be voluntary or involuntary. As people leave an organisation for a multitude of reasons, that may not be management related. A further categorisation of turnover is controllable or unavoidable (Khilji & Wang 2007).
