The study examines the relationship between distributive justice and teachers' lateness, focusing on the mediation effect of organizational commitment and taking into account gender differences. The sample consisted of 1,016 teachers from 35 high schools in Israel. Results, based on multi-level analysis, showed that, for women, organizational commitment partially mediated the relation between perceived distributive justice and lateness. No such effect was found for men. The findings are explained in terms of women using lateness behavior to establish a balance between their amount of effort and the measure of their perceived reward.
