The purpose of this study was to identify the relationship between work values congruence and organizational commitment as well as to determine the comparison between demanded work values between generation X (Gen-X) and generation Y (Gen-Y) cohort generation staff in the field of Accounting and Finance in the Klang Valley, Malaysia. This is because information regarding workplace diversity is very important to create a better workplace environment in stimulating organizational effectiveness specially to cater on different age among employees. Therefore, this research used a quantitative, survey and purposive sampling involving established instruments; these include Work Value Inventory (WVI), Work Value Congruence Scale (VCS), and the Organizational Commitment Questionnaire (OCQ). The results of Pearson correlation analysis among 169 respondents showed that there was a significant relationship between the work value congruence and organizational commitment (r = 0.617, k 0.01). In addition, a t-test analysis indicated only six dimensions of demanded work values were significantly different between Gen-Y and Gen-X including management, prestige, nature of supervisor, lifestyle, economic returns, and variety of task. From these, Gen-X had higher mean score in management, prestige, nature of supervisor and lifestyle; meanwhile, Gen Y had higher mean score in economic returns and variety of tasks. This research implies that there is a significant difference between Gen-X and Gen-Y in terms of demanded job values; in which, the congruence work values was significantly correlated with organizational commitment. Therefore, employers need to be more careful and vigilant in managing the job behaviour of Gen-X and Gen-Y employees to ensure that both generations can work as a team and sustain a high level of work performance.
