Organizational citizenship behavior (OCB) is of key importance in the workplace. Researchers have discussed numerous motivation factors affecting OCB, but they have not examined the relative contributions of job standardization to OCB. This article describes an empirical study that examined the relationship between job standardization and OCB in the hospitality sector. Regression analysis of survey data from 214 hotel employees supported the relationship between job standardization and OCB. ANOVA analysis revealed that high degrees of job standardization indicate a higher level of OCB.
