This research is conducted through the collection of data from 600 white-collar working adults in Teknopark and Industrial Regions manufacturing firms in Istanbul, using a mail questionnaire. The result shows that both job satisfaction variable except “payment” sub-dimension and innovativeness sub-dimension of corporate entrepreneurship are positively and significantly correlated with all OCBs (i.e., courtesy- altruism, conscientiousness and civic-virtue). Overall, job satisfaction has a mediator role between corporate entrepreneurship and organizational citizenship. Principled local ethical climate has a linear moderator effect between CE and OCB; it strengthens the positive relationship between them. However it does not show any curvilinear moderator effect on that relationship. Principled local ethical climate (PLEC) has both linear and curvilinear moderator effect on the relationship between JS and OCB. As a result, the study helped to find-out the moderator role of ethical climate in the triangle of JS, CE, and OCB relationships. This study has contributed to literature a few novelties such as: (i) to test all these constructs relations in Turkish case as a developing country and; (ii) to investigating the possible moderating role of ethical climate on these constructs more different than previous studies have already done and more detailed within sub-dimensions effects. Keywords: Curvilinear and Linear Relationship, Moderating Analysis, Turkey. INTRODUCTION Especially, since the beginning of 2000s, various researches have been accomplished concerning unethical behavior in business organizations (e.g., Koh and El’fred 2001, Turnipseed 2002, Valentine et al. 2002, Tsai and Huang 2008, Toor and Ofori 2009). There is still a lack of understanding concerning how organizational ethics support business in both co-operative and entrepreneurial way. The focus of this study is on principled ethical climate that is systematically related to ethical working style and decision making on job. From multidimensional of ethical climate, only principled ethical climate has been taken into consideration which was appropriate to measure ethical behavior in workplace. Indeed, a uni-dimensional scale is used (so single dimension assessment is used). Next, although ethical climate has been investigated for its relationship to employee attitude such as job satisfaction (Podsakoff et al. 2000), but few studies have examined its relationship to organizational citizenship behavior and corporate entrepreneurship (Turnipseed 2002, Valentine et al. 2002, Gonzalez- Padron et al. 2008, Greenslade and Jimmieson 2011). Organizational citizenship behavior is especially interesting variable to study in relation to organizational ethics because based on its nature it varies according to employees attitudes rather than work-it-self (rather than job performance). Finally, with regard to the literature, it is investigated in this study the role of job satisfaction, corporate entrepreneurship and organizational citizenship in relation to ethical climate. Specifically, overall organizational citizenship behavior is a reflection of the extent to which employees share “conscientiousness, civic virtue and courtesy/altruism” in the organization. Various types of values have
