    (Addis Ababa University, 2006-06) Alemu, Tewodros; Jekale, Wubishet(phD)
    The research is about systematic measurement of labour productivity to indicate whether construction labor productivity is low in the case of building projects in Addis Ababa, and if it is; to assess productivity problems and their causes. A review of other country studies, project reports and consultation with practitioners were made to identify the productivity problem areas and process factors for inclusion into the study instruments. A case study of seven projects on three construction trades, namely concrete, steel reinforcement placing and masonry works, revealed that 11 front line factors are responsible for low productivity; the major ones in the order of their rank are lack of materials, instruction delay, rework, change of workers, lack of tools and less work load and congestion. The research result showed that nearly all projects (except project 5) have a productivity performance ability ratio (PAR) greater than one indicating that the studied crews’ productivity performance was low. In addition opinion survey of foremen on the amount of effective productive time of workers showed that on the average the studied craftsmen spend only 56% of the total paid time. An open system theory of management was applied to identify the major managerial causes of productivity, which resulted in four factors contributory to low labor productivity; these are: external precondition factors, technical management sub system, managerial systems and organizational behavior factors. That is; The causal problems for low productive performance was analyzed and it was found that unfulfilled conditions from project site external bodies, lack of project management systems, poor technical management in areas of developing productivity standards and construction methods, average leadership efficiency and low project culture towards workers satisfaction are responsible for low productivity performance. Key words: process factors, open system theory, construction trades, performance ability ratio (PAR)

    The main objective of this study is to investigate the relationship between leadership styles and employee commitment in Bank of Abyssinia, Addis Ababa selected Branch offices. The study employed descriptive research design with emphasis on the relationship of leadership styles on the employee commitment in Bank of Abyssinia. The target population of interest in this study was made up of non-management employees of 12 grade three branch staffs of the bank, who were 322 in total which is obtained from the HR department. The sample size consists of a list of 50 randomly selected staffs from each of the 12 branch offices. Data was collected using questionnaire (two separate instruments namely Multifactor leadership questionnaire, MLQ& Organizational Commitment questionnaire, OCQ) and analyzed using the Statistical Package for Social Science (SPSS). The findings were presented using tables and charts. Correlation analysis was also being employed to test the relationship between the independent and dependent variables. The findings of the study revealed that transformational leadership style has significant and positive correlation with affective, continuance and normative employee commitments while transactional leadership style has not significant and positive correlation with all the three types of commitment. A laissez-faire leadership style is found to be not significantly correlated with affective & normative commitment but significantly and positively correlated with continuance commitment. Finally depending on the research work the researcher recommended that the bank could work on strengthening and intensively using Transformative leadership style by equipping managers on the skills needed for transformational leadership since this leadership style has proved to be significantly correlated with employee commitment
