The willingness of employees to report deviant behavior at the workplace in this paper is analyzed as one of the four dimensions of organizational and cultural approach to deviant behaviors. The study was conducted on a sample of 70 employees of Međimurske vode company whose headquarters are in Međimurje County. The company deals with the distribution of water and maintenance of water supply and sewerage system. Data required for the survey was collected on the basis of the customized questionnaire about professional integrity seeking the opinion of employees of 10 different situations according to the original questionnaire which was created by Klockars and Kutnjak Ivković (1999). We calculated the basic statistical parameters and then set out indicators of reliability of the questionnaire (Cronbach's alfa = 0,81). Further results were obtained by the T-test and correlation analysis. There was a statistically significant association between the willingness of employees to register deviant behavior in the workplace and the sex of employees, their age, years of employment in the company and position within the company. However, no statistically significant correlation between the willingness of employees to register deviant behavior in the workplace and their educational qualifications were identified. Observing the results it can be noticed that there is a need to improve outreach in order to prevent theft of materials, fraud and additional costs that the company could have. That can be avoided by introducing various checks and promissory notes. Arrangements between construction site manager and contractor about the fictitious costs and benefits at the expense of appropriation Međimurskim waters have been identified as the most serious scenarios and employees are most willing to register them. The results indicate that the Međimurske vode is an organization that has managed to create an organizational culture intolerant of deviant behaviors and are characterized by a high level of professional integrity.
