This article analyses if and to what extent the PSM level of public employees depends upon the policy domains (welfare, utilities, infrastructures and environment, core state functions and general administration), and the stage of the policy cycle (formulation and implementation) in which they are involved. The empirical results obtained from a sample of 6'885 Swiss civil servants working in municipalities and cantons show that differences among policy sectors principally impact one dimension of PSM: employees in charge of policies related to the welfare State are inclined to have higher levels of "Compassion", whereas those responsible for security, legal services and justice policies report lower levels. Furthermore, civil servants whose main tasks are related to policy formulation are more prone to developing high levels of the "Attraction to politics" dimension of PSM. Consequently, this study questions the generalisability of previous findings on PSM that are based on heterogeneous survey populations.
