Abstract:In this paper we report the results of a study exploring psychological contract breach (PCB) in a heterogeneous sample of Croatian employees (N=363). In addition to reporting PCB, the participants informed us about their basic demographic characteristics, job attitudes (job satisfaction and organizational commitment) and reported three aspects of their job performance (in-role performance, organizational citizenship behavior, counterproductive work behavior). Our analyses showed that PCB experience depended on participants' characteristics, and, more importantly, was negatively related to job attitudes and job performance. Thus, the detrimental effect of PCB reported in the organizational behavior literature was replicated among Croatian employees.
