When hygiene factors become motivation: a moderated mediation analysis of gender, hierarchy, and job satisfaction in Saudi Arabia’s public sector

PurposeSaudi Arabia’s Vision 2030 has rapidly expanded female government employment and reformed performance accountability, yet how gender and hierarchical job level shape motivation, satisfaction dynamics in this context remains untested. This study examines whether these demographic boundary conditions moderate the indirect effects of intrinsic and extrinsic motivation on job satisfaction through supervisory communication and recognition.Design/methodology/approachA stratified random sample (N = 311) from four Saudi central ministries completed a bilingual 25-item instrument combining the Multidimensional Work Motivation Scale (MWMS) and the Minnesota Satisfaction Questionnaire, Short Form (MSQ-SF). First-stage moderated mediation (PROCESS macro Model 7) with 5,000 bootstrap samples and bias-corrected confidence intervals constituted the core analytical model.FindingsExtrinsic motivation predicted satisfaction more strongly than intrinsic motivation (z = 2.81, p = 0.005), a reversal of Herzberg’s asymmetric prediction. Supervisory practices partially mediated both pathways. The intrinsic pathway was significantly stronger for female employees than for male employees [Index of Moderated Mediation (IMM) = 0.08, 95% bias-corrected confidence interval (BC CI) (0.02, 0.15)]; the extrinsic pathway was significantly stronger at lower hierarchical levels than at director level [IMM = −0.05, 95% BC CI (−0.09, −0.02)]. Cross-pathway moderations (gender × extrinsic; job level × intrinsic) were not supported. Effects are cross-sectional.Theoretical contributionHerzberg’s hygiene, motivator boundary does not hold in this collectivist, high power-distance setting: supervisory recognition, classified by Herzberg as a hygiene factor, operates as an active mediating pathway whose strength varies systematically with gender and hierarchical level. The asymmetry between supported hierarchical moderation of extrinsic motivation and non-supported moderation of intrinsic motivation aligns with Maslow and Alderfer Existence-Relatedness-Growth (ERG) predictions of differential need activation across hierarchical strata.Practical implicationsFindings indicate that supervisory leverage on satisfaction varies systematically with employee demographics: extrinsic recognition is more consequential for satisfaction at entry levels, and intrinsic engagement is more consequential for female employees. Pilot implementation across two-three departments per ministry is recommended before ministry-wide policy adoption.Originality/valueThis study tentatively proposes the Constrained Need Activation (CNA) idea as a preliminary, context-specific conceptual proposition for motivation, satisfaction dynamics in collectivist public-sector environments, requiring future replication before broader generalisation. It extends related Gulf Cooperation Council (GCC) studies through the simultaneous test of gender and job-level moderation in Saudi central government during Vision 2030 implementation.
