Employees creativity has been recognized as a crucial part of an organization’s ability to be innovative. To know which factors contribute to employee involvement in creative work, in this paper, we first examine the effects of corporate social responsibility (CSR) to employees. Moreover, we study the employees’ positive work attitudes and their intention to leave as a mediating mechanism to explain the effect of CSR to employees on the involvement of employees in creative work. Survey data from 209 employees in 45 small-sized enterprises in Iran were used to test the hypotheses of the study. The hypotheses were tested with hierarchical regression analyses using SPSS software. The results support the direct impact of CSR to employees on employees’ creative work involvement. In addition, the findings indicate that the indirect effect of CSR to employees on the involvement of employees in creative work through positive work attitudes and their intention to leave are significant. Consequently, small-sized enterprises should reinforce CSR to employees to elevate their involvement in creative work.
