Design/methodology/approach - Military leaders (n = 50) completed a questionnaire with Theory X and Y scale and their subordinates (n = 150) completed a questionnaire with the scales of satisfaction with leader, affective commitment, and organizational citizenship behavior. The paper used hierarchical linear modeling to test the hypotheses. Findings - The results indicated that the Theory Y management style is significantly and positively associated with subordinates' satisfaction with the leader, affective commitment, and organizational citizenship behaviors. The Theory X management style had a significantly negative impact on subordinates' satisfaction with the leader, but no significant impact on affective commitment and organizational citizenship behavior. The findings of the present study suggest that the Theory X and Y managerial assumptions are a worthwhile basis from which to examine several important organizational and individual outcomes. Research limitations/implications - The sample consisted of military personnel and were predominantly male. This may limit the generalizability of the findings. Practical implications - The findings of the present study suggest that the Theory X and Y managerial assumptions are a worthwhile basis from which to examine several important organizational and individual outcomes. Originality/value - Although McGregor's (1960) Theory X and Y have contributed to management and leadership thinking and practice for many years; empirical studies examining the Theory X and Y managerial assumptions in a work environment are very scarce. By examining the effect of leader's Theory X and Y managerial assumptions on follower's attitudes and behaviors, the study provides important insights for leadership literature.eninfo:eu-repo/semantics/closedAccessAffective commitmentOrganizational citizenship behaviourSatisfaction with leaderSocial exchange theoryTheory X and Y management stylesMilitary personnelArticle52101888190610.1108/MD-06-2013-03572-s2.0-84927586143Q1WOS:000348347700002Q2
