uman resources are now one of the major issues which increasingly attract the attention of writers and researchers on economy. This comes in the framework of efforts made to find the ideal combination of factors of production capable of achieving the highest return for the organization whether in the micro or macro economy. This is only possible with an effective system or managing these resources inside the organizations that can utilize all the workers capabilities, skills and interests and expand the extent of individual contributions to the production process and create factors which together contribute to preparing a system to control the performance of the work. Consequently the role played by human resources is not limited planning, attracting and motivating labor force, but goes far beyond to seek the successful means and programs that can retain and evaluate such resources.
