ABSTRACT This study examined “The impact of Manpower training on productivity in Public Service. (A case study of Nnewi North local government from 1999- 2007). It has been observed that with only manpower training and development, a relatively permanent change can be brought about in the behaviour of the individual employee and subsequently in organization. Training often is considered for new employees only. This is a mistake because ongoing training for current employees helps them adjust to rapidly changing job requirements. However, this work examines whether the training organized by the Nnewi North local government have improved their productivity. It further investigates how successful or unsuccessful training organized by the authority have been. The major findings of this study were that workers were not well integrated after training. Secondly, that workers experience “job dissatisfaction” because of inadequate training given to them by Nnewi North local government authority. The researcher however recommended that the activities of those who were in charge of staff training should be monitored and not left in the hands of politicians. Also, that returnee staff from training should be well integrated to post in which the training undertaken applies.
