Purpose The psychological contract breach (PCB) literature has documented the negative effects of PCB on employee job attitudes and the variables that moderate (accentuate or mitigate) this relationship. Given that multiple variables together influence a subordinate’s PCB – job attitudes relationship, this paper aims to investigate a three-way interaction between corporate reputation, supervisor’s and subordinate’s PCBs on the job attitudes of the latter. Design/methodology/approach The authors collected a dyadic sample of 227 employees and their 79 supervisors from some of the well-known companies in Oman. The authors used SPSS (version 25) to examine the three-way interaction of focal employee PCB, supervisor PCB and corporate reputation on employee job attitudes. Findings The results indicated that depending on the perception of corporate reputation, the extent of the supervisor’s PCB perception has a differential influence on the employee PCB – job attitudes relationship. Originality/value By investigating the joint (sometimes conflicting) influences of multiple moderators which enhances the ecological validity, this paper makes an original and important contribution to the PCB literature.
