This article analyses trends in violence at work on the basis of victim surveys, work-environment surveys, and press material. It proceeds from the two most common explanations of why violence at work appears to have increased over recent decades. These emphasize shifts in working conditions that have increased employees' victimization risk, and a broadened view of what is regarded as work-related violence. The empirical analyses provide support for both these explanations, and the various dimensions examined—increased reporting propensities, expanded definitions, a reduced tolerance of violence, and altered working conditions—are linked to one another.
