The mediating effect of workaholism in the relationship between teacher and principal behaviours related to school climate and organizational commitment

It was aimed to determine the mediating effect of workaholism in the relationship between teacher and principal behaviours related to school climate and organizational commitment in this study. The study was designed through correlational survey method. Organizational Climate Scale, DUWAS (Dutch Work Addiction Scale), Meyer and Allen Organizational Commitment Scale were used as data collection tools. 266 teachers working at primary and secondary schools in Kütahya Province created the sample of the study. In accordance with the aim of the study, 18 measurement models were set and tested by structural equation modelling. In terms of the findings, the tests of only two models are successful. It is statistically proved that workaholism has a mediating effect only in the relationships between supportive principal behaviour and normative and continuance commitment dimensions of organizational commitment. The positive relationship between supportive principal behaviour and organizational climate strengthens with the workaholic behaviours the teachers experience. In other words, workaholic teachers are more committed to their organizations in which the supportive principal behaviours are observed in comparison with their colleagues. However, any mediating effect of workaholisim cannot be found in the relationships between directive principal behaviour, restrictive principal behaviour, collegial teacher behaviour, intimate teacher behaviour, disengaged teacher behaviour and organizational commitment.
