PurposePrevious research is equivocal about: whether affective organizational commitment increases or decreases with increasing tenure; and which psychological climate variables correlated with affective commitment are important as tenure increases. The study's purpose is to examine whether the relationship between psychological climate and affective commitment is moderated by tenure.Design/methodology/approachThe total workforce of a public sector agency in Western Australia (n=1,117) was surveyed with a response rate of 53 per cent. The moderating role of tenure was examined for employees with less than one year's tenure (n=87), one to nine years (n=232) and more than nine years (n=258).FindingsAffective commitment was found to be stronger for employees with longer tenure; however, perceptions of psychological climate appear to be less positive for these employees. The finding of a moderation effect for tenure appeared to be attributable to the importance of supervisor involvement to affective commitment for employees with one to nine years' tenure.Practical implicationsBuilding affective commitment is an important issue for managers as it is strongly related to withdrawal cognitions and employee turnover. The findings of the study suggest that the criteria against which an organization is assessed by employees tends to shift with time and impacts on affective commitment.Originality/valueThe three‐way relationship between tenure, psychological climate and affective commitment has received little attention. The findings of the study suggest that the strength of affective commitment may depend on the extent to which the specific interests and capabilities of individual employees at different stages of tenure are met.

This study investigates the relationship between cynicism, the perceived fairness of change management and personnel practices, and affective organizational commitment. High levels of affective organizational commitment have been shown to reduce voluntary turnover in the nursing workforce. Previous research suggests that "unfair" management practices and employee cynicism lead to lower commitment. It is not clear, however, whether the perceived fairness of particular practices influences affective commitment beyond that accounted for by underlying employee cynicism. Data were obtained from a study involving 1104 registered nurses that formed part of a larger investigation of the general well-being of nurses in Western Australia. Only nurses who were permanent or employed on fixed term or temporary contracts were included. Findings indicated that although higher levels of cynicism among nurses were associated with lower levels of affective commitment, their perception of the fairness of change management and personnel practices influenced their affective commitment over and above their cynicism. The perceived fairness of management practices is an important influence on nurses' affective commitment beyond that accounted for by cynicism. The implication for managers is that the affective organizational commitment of nurses is likely to be strengthened by addressing the perceived fairness of change management and personnel practices notwithstanding their beliefs about the integrity of the organization.
