This article relates three concepts that are among the most important concerns of human resources managers: workload, career capping, and organizational commitment. A quantitative survey of 1,134 managers affiliated to the French Confederation of Management – General Confederation of Managers has allowed us, using structural equation modeling, to conduct statistical hypothesis testing and validation of the research model through exploratory factor analysis and confirmatory factor analysis. The results revealed a positive correlation between, on the one hand, workload and career capping and, on the other hand, organizational continuance commitment. There is also a negative correlation between these two variables and normative organizational commitment. The affective dimension has a significant positive link only with career capping.
