Theory and research on the psychological contract have focused on its links to affective commitment and, to a lesser extent, continuance commitment (See Raussoau & Wade-Benzoni,1995). The literature contains suggestions, however that the specific form of commitment most closely associated with psychological contracts differs somewhat from both of these. For example, Robinson et al. (1994) observed that commitment characterized by affective attachment or identification (affective commitment) or by investments in the organization (continuance commitment) “touch on but do not directly confront the role of obligations, reciprocity and fulfillment” (p.149). Normative commitment, with its distinct emphasis on obligations, might well be the “missing link” in our understanding of the influence of psychological contracts on employee commitment.
