– The purpose of this paper is to investigate the influence of employees’ perception of organizational climate on organizational citizenship behaviour outbreak and the impact of both of them on organizational performance.

– This survey has been performed using structural equation modelling (SEM). The statistical population composed of the managers of Mazandaran small- to medium-sized enterprises. The analysis of the data obtained from distributed survey questionnaire has been performed by SPSS18 and AMOS18 software.

– Findings imply that positive perception of organizational climate influences on increasing organizational citizenship behaviour outbreak and performance of enterprise, and organizational citizenship behaviour in turn has positive and significant impact on organizational performance. Results of this survey also indicate that organizational citizenship behaviour impacts on sub-criteria of enterprise performance (i.e. financial, customer, learning and growth, internal processes). Moreover, the influence of organizational climate on all sub-criteria of performance except internal processes has been confirmed.

– Lack of sufficient information concerning organizational climate in internal resources, and in some external ones, and low number of surveys performed in this field, limits the possibility of comparing the results of this survey with other similar surveys.

– This survey can be considered as an innovative survey, since there is no similar survey conducted in which three variables of organizational climate, performance, and citizenship behaviour studied, considering their specified sub-criteria.
