The purpose of this study was to examine the effect of perceived leadership style as independent variable and its implication on the level of employees' motivation as a dependent variable. The dimensions are Transformational leader ship style and Transactional leadership style dimension and considering Laissez faire leadership style for both transformational and transactional leadership dimension. A quantitative approach and across sectional survey design was used to gather data pertaining to the impact of effective leadership on employee motivation for the purpose of the research objectives and a multiple linear regression analysis research design were used in this study. Nine hypothesis were proposed to test the relationship between the transformational, transactional and laissez fair leadership style dimensions and employee motivation. The research instrument was a structured questionnaire. The Multifactor Leadership Questionnaire (MLQ) was adapted to measure the different dimensions of transformational leadership style while motivation was measured using seven motivational drivers (Motivation potential assessment(MPA)-(wonderlic/www.wonderlic.com/)itemsdrawn from preexisting questionnaires. The questionnaires contain different elements drawn from the full range leadership development model, developed by Bass and Avolio(1995) MLQ)and employees motivation from seven motivational potential assessments. The findings of the study revealed that Intellectual stimulation, idealized influence behavioral dimensions of transformational leadership style and management by exception active and laissez faire leadership dimensions of transactional leadership style were found to be significantly related to motivation. It is recommended that they adopt a transformational leadership style rather than transactional or laissez-faire styles to enhance employee’s motivation consistently and efficiently; which will in turn generate higher quality performance on the employee’s part and boost business performance and the leaders should avoid any laissez-faire behavior.
