Abstract. The purpose of this longitudinal study is to test the association between satisfaction with traditional benefits and perquisites and turnover via the mediating effect of organizational commitment. Data come from a series of electronic surveys conducted among a sample of new employees working in the Canadian division of a large international Information and Communications Technologies (ICT) firm. Results indicate that while satisfaction with traditional benefits has both a direct and indirect effect on turnover, satisfaction with perquisites only has an indirect effect on turnover via organizational commitment. Results also show that satisfaction with traditional benefits has a stronger impact on turnover than satisfaction with perquisites.
