This study focuses on immigrants in Canada and examines their job satisfaction as compared to Canadian-born employees. The authors explore whether high performance work systems (HPWS) affect immigrant employees’ job satisfaction differently than Canadian-born, where HPWS include empowerment, motivation and skill enhancing sub-bundles of practices. The study uses Statistics Canada’s Workplace and Employee Survey, a longitudinal dataset consisting of six years of data from 1999 to 2004 and 49,344 employees. Ordered logistic regression analyses are used to explore causal relationships. The moderation results show that increases in the motivation sub-bundle and increases in overall experience of HPWS practices are related to increases in job satisfaction among immigrants when compared to Canadian-born employees. Immigrants are a segment of the workforce that is understudied in management. This study identifies HPWS bundles that positively affect immigrants’ job satisfaction, suggesting a role for managers to capitalize on job satisfaction improvements ultimately contributing to organizational success.
