The aim of this article is to investigate how span of control influences seven job demands common amongst operational public sector managers. Self-administrated surveys were collected from 434 managers organized in 37 municipal operations, i.e. management teams in a set of public organizations in Sweden, and complemented with register data. Multilevel analyses were performed and it was shown unfavorable to have a large number of subordinates for the majority of job demands investigated. Furthermore, managers who were members of management teams with a higher average span of control experience some job demands to an even higher extent. Thus, the results of this study demonstrate that span of control is a key upstream component of managers’ job demands and emphasize the value of a reasonable number of subordinates.
