Commodity chains that are global in extent have increasingly come to be seen as the defining element of the contemporary globalized world economy. Since the 1990s a body of theory — evolving from global commodity chain analysis to global value chain analysis to global production network analysis — has focused upon understanding how such commodity chains function. However, despite providing many important insights, these bodies of literature have generally suffered from a major deficiency in that they have failed to consider labour as an active agent capable of shaping such chains' structure and geographical organization. Here, then, we present a case for locating more centrally labour, in production network analysis.

Theorists of work and employment (W&E) practices should more seriously engage with literatures concerning how space is constitutive of social praxis. Rather than simply serving as a stage upon which social life is played out or being merely a reflection of social relations, the construction of the economic landscape in particular ways is fundamental to how social systems function. Struggles over space are a central dynamic in W&E practices as different actors engage with the economic landscape to ensure their 'geographical vision' is emplaced in that landscape. Furthermore, conflicts over W&E practices frequently revolve around the spatial (re)scaling of such practices (as when collective bargaining is 'decentralized'). Consequently, an important key to better theorizing W&E practices is understanding how the various spatial scales at which these operate are socially constructed and discursively represented.

Purpose -The purpose of this paper is to introduce a conceptual model that integrates multi-disciplinary research in relation to crisis management, and to consider its application for international human resource managers in preventing and managing the evacuation of expatriate staff during crises. Design/methodology/approach -The paper critically reviews and distils research into crisis and evacuation management, and examines its relevance to a generic framework of international human resource roles. The paper evaluates this body of literature and suggests potential research avenues from an international human resource perspective. Findings -The review reveals a dearth of research on emergency evacuation of expatriates from a human resources perspective. The paper articulates a framework that delineates what role human resource managers could, or should, play during crisis preparation and response. This framework aims to establish a basic "roadmap" for use by practitioners and researchers. Originality/value -Focusing on the human (rather than business) implications of crises, the paper links crisis management literature to the role of international human resource managers in supporting the health, safety, and security of international assignees during crises. A framework is presented which enables managers to map their current (and potential) contributions to preventing and managing expatriate evacuation. From this, several avenues of future research are drawn.
