Does job satisfaction of street-level bureaucrats depend on intrinsic public service motivation (PSM) or extrinsic performance-contingent pay? Which factor exerts a more substantial impact on job satisfaction? Drawing on a data set of 220 frontline public service workers in Hong Kong, this study examines the nuanced relationship among PSM, performance-contingent pay, and job satisfaction. The findings show that both PSM and performance-contingent pay elevate the job satisfaction of street-level bureaucrats through a shared mediator-perceived job control. Furthermore, PSM, as an intrinsic motivator, exerts a stronger impact on job satisfaction than performance-contingent pay.
