International labor organizations global report on work life conflict of 2010 rates Kenya among those with the highest prevalence of long working hours more than 48 hours per week. The objective of the study was to determine the influence of work life conflict on organizational performance in the banking industry in Kenya. The null hypothesis was that there is no significance influence of work life conflict on performance of the banking industry in Kenya.This study adopted survey research design using both quantitative and qualitative approaches. The study covered all the 43 banks registered by Central Bank of Kenya focusing on branches in Nairobi with the target population of 36,212 employees. Primary data was collected using questionnaires that had both structured and unstructured questions. The researcher used descriptive statistics including frequency distribution tables, percentages and measures of central tendency such as mean. In addition to this advance statistical techniques were also considered particularly measures of variations such as standard deviation and others like regression analysis to establish relationships among variable. The study results indicated that this relationship was negative which means it was not significant in influencing performance. This implies that work life conflict is in contrast with the implications of performance hence did not have a linear relationship with performance which was measured in terms of customer satisfaction, target standards and employee satisfaction. Based on the findings of this study, it can therefore be concluded that majority of the banks sampled in this study, work life conflict did not influence their performance. In qualitative responses, respondents indicated that they were able to balance their schedules and time between work and other aspects may it be family, personal and social aspects. The study recommends that banking institutions need to address issues of too much work, long working hours, work and family balance of its employees because respondents reported to having inadequate time to spend on personal, leisure and family, although work life conflict was not significant in influencing performance.
