Diversity management may be understood as the systematic and planned commitment by organisations to recruit, retain, reward, and promote a heterogeneous mix of employees (Thomas, 1991; Ivancevich and Gilbert, 2000). It is directed at enabling the diverse workforce to achieve its full potential in a work environment that is equitable and where no group has any superficial advantages (Torres and Bruxelles, 1992). Furthermore, managing diversity is based on the assumption that diverse groups will create new ways of working together and that morale, profit and productivity will increase. It tries to build specific skills and to create policies that derive the best from each employee (Sadri Golnaz and Tran Hoa 2002).
