This paper discusses how different forms of cross‐border employee mobility all contribute to establishing social ties across different units of multinational enterprises (MNEs). Despite the growing recognition of the significance of employees' cross‐unit social ties in MNEs for both individuals and the organisation, the mechanisms for creating such ties remain underspecified. We contribute to closing this gap by identifying the role that an array of forms of international mobility can play in promoting employees' (cross‐unit) social ties inside MNEs. We draw upon empirical accounts of the job‐related international mobility experiences of 72 high‐skilled employees in three leading MNEs in the mobile telecommunications sector. Guided by a framework that utilizes some of the key concepts of the debate on social ties and social capital, we discuss traditional expatriation, short‐term assignments, localised transfers and business travel in terms of the structure and strength of the cross‐unit ties they engender, as well as their accessibility. We find (1) that it is not only traditional long‐term assignments in the form of expatriation that enable individuals to create cross‐unit social ties; and, (2) that different forms of international mobility promote cross‐unit social ties in variable ways and to different extents.

There is increasing evidence that multinational enterprises (MNEs) from less dominant economies tend to mimic and disseminate human resource management (HRM) practices sourced from a dominant economy, usually the United States, to overcome their "liabilities of origin." However, our understanding of the specific challenges involved in the implementation of such practices by firms across different national and subsidiary contexts remains limited. Drawing on evidence from a case study of a South Korean MNE, we examine the extent to which, and ways in which, global HRM policies mimicking U.S. practices are implemented across its sales, manufacturing, and research and development subsidiaries in the United States and India. We find discernible differences in the implementation of the global policies both between the two host country sites and across the three function-specific subsidiaries in each country, identifying a range of national and subsidiary-specific factors that inform these variable implementation outcomes. In addition to legitimacy challenges related to the source, appropriateness, and process of transfer, we note a unique form of legitimacy challenge-"the liability of mimicry"-whereby local actors can challenge head office policies on the basis of a claim to superior expertise in the dominant practices, as a particular concern of MNEs from emerging economies.

This article argues that the characterization of ‘extreme jobs’ as being defined by the constancy of ‘extreme work’ obscures the significance of temporary episodes of ‘extreme work’ for a wider range of jobs and notes that even ‘mundane jobs’ are punctuated by extreme work in a variety of cases. Drawing on a study at a supermarket deli counter during the Christmas trading season, it is proposed that work in this context becomes extreme, in relative terms, in three ways. First, the expansion of the scope of work entails an increase in working hours, an increase in demands for multi-tasking and product knowledge, and an expansion of discretion. Second, an increased mobilization of soft skills is necessitated by intensified work both front stage and backstage. Finally, the Christmas period also entails an extension of ‘inclusive’ management practices over a group of workers who are not typically the focus of such efforts. Four key insights are offered in conclusion: First, ‘extreme jobs’ and ‘extreme work’ are conceptually distinct, and the latter is a relative and relational term that varies with the normalized nature of different jobs; second, the temporality of ‘extreme work’ is variable, as it occurs in different rhythms on different jobs; third, the subjective experience of punctuations of mundane jobs with extreme work can be highly positive; and finally, Christmas deserves further attention in discussions of recurrent and temporary intensification of work, particularly in understanding retail employment.

This paper discusses the literature on the established determinants of productivity in the retail sector. It also draws attention to some neglected strands of research which provide useful insights into strategies that could allow productivity enhancements in this area of the economy. To date, very few attempts have been made to integrate different specialisms in order to explain what drives productivity in retail. Here we rectify this omission by putting together studies from economics, geography, knowledge management and employment studies. It is our view that quantitative studies of retail productivity should focus on total factor productivity in retailing as the result of competition/composition effects, planning regulations, ICT, the multinational operation element and workforce skills. Further, the fact that retail firms possess advantages that are transferable between locations, suggests that investment in strategies enhancing the transfer of explicit and tacit knowledge between and within businesses are crucial to achieve productivity gains.
