Although the psychological contract has been a popular topic in managerial research for the past twenty years, recent critiques of the research in this area point to several shortcomings. These are believed to result primarily from the overwhelming use of field studies, survey questionnaires, and other correlational procedures in the study of this construct. One particular research question that has generated mixed results involves the effect that one's underlying contract (either transactional or relational) has on individuals' perceptions of contract breach and feelings of violation following an employer's breach. This study sought to gain insight into this question by using an experimental study design to assess the impact that exchange congruence — or the match between the nature of the underlying contract and the nature of the breach — has on employees' perceptions of breach and feelings of violation. An experimental design was used and data was collected from 421 subjects in six treatment groups and two control groups. The treatment groups examined the effects of withdrawal breach (without resource substitutions) and both congruent and incongruent resource substitutions in transactional and relational work contexts. Also, two control groups in which no psychological breach was induced were examined. The results of the experiment differ for the transactional and relational treatments. No significant differences in perceptions of breach or violation were found with regard to the type of breach induced among the transactional treatments. Among the relational treatments, subjects that received incongruent resource substitutions perceived significantly higher levels of breach and violation than those that received congruent substitutions. Also, among the relational treatments, levels of perceived breach were significantly higher for the incongruent substitute treatment than for the withdrawal breach treatment. Therefore, the results of this study indicate that breach perceptions and feelings of violation vary for employees depending not only on the type of contract they hold, but the type of breach that they experience. In addition, the study demonstrated that an experimental design is applicable to this literature and that it could advance our understanding of the psychological contract in ways that are not possible with cross-sectional field studies. / Ph.
