Job redesign is the restructuring of the elements of work in order to make it more encouraging and inspiring for the employees. Even though redesign has been recommended as a means of improving performance in organizations, its effect on the performance of employees in the banking sector in Kenya, has not been empirically investigated, yet all banks have embraced it as a core strategy. This study sought to determine the effect of job redesign on the performance of employees in commercial banks in Kisumu City. The study adopted a cross sectional survey research design. A sample of 297 randomly selected staff of commercial banks was picked. Questionnaires and interview schedules were used to collect primary data. Data was analysed using descriptive statistics. The study established that task identity, task variety and task significance affects the performance of employees of commercial banks in Kisumu, but that task autonomy does not affect the performance of employees of commercial banks in Kisumu. The study concludes that job redesign affects the performance of employees and recommends that commercial banks create a high degree of task identity for their employees.
