The present study aims to identify organisational antecedents of public service motivation (PSM). According to the current scientific literature, organisational antecedents of PSM have been understudied thus far. In order to fill this research gap, we question whether human resource management practices might be related to PSM. Our findings, based on a survey in an important Swiss municipality (N = 859), surprisingly highlight that extrinsic HRM practices are significantly related to PSM, whereas intrinsic ones are not. Furthermore, when taking into account work-related outcomes, such as job satisfaction and organisational commitment, there is evidence of full mediation effects towards extrinsic HRM practices from organisational commitment.
