PurposeThis paper aims to investigate the impact of total quality management (TQM) practices on the work-related attitudes of International Non-Governmental Organisations (INGOs) staff, including job involvement, job satisfaction, career satisfaction and organisational commitment.Design/methodology/approachThe paper developed and tested 16 hypotheses on the relationship between TQM practices and work-related attitudes. Out of 295 targeted staff working for 59 INGOs operating in Jordan, 126 staff have responded to the research questionnaire. The collected dataset has been analysed using the structural equation modelling-partial least square (SEM-PLS) technique.FindingsAnalysis of the data revealed the significant positive effect of TQM practices. Beneficiary focus, empowerment-teamwork and continuous improvement impact 35% of job involvement. Meanwhile, beneficiary focus and empowerment-teamwork affect 34 and 47% of career satisfaction and organisational commitment, respectively. Significantly, empowerment-teamwork and continuous improvement determine 62% of job satisfaction. However, the low extent of training and education is challenging to enhance employees' positive emotions.Practical implicationsThis research provides further evidence on the importance of TQM practices to the leaders of INGOs. Therefore, to orient their resources towards TQM implementation to enhance work-related attitudes, and in turn, the performance of interventions in this challenging sector.Originality/valueThis research extends the knowledge regarding certain TQM practices that naturally and variably empower job and career satisfaction, job involvement, and organisational commitment within the INGOs. Therefore, to confirm the validity of this research direction in a new uncovered sector, which has its own specificities.
