Key questions remain as to the relative weight of macro-and micro-level influences on union status at subsidiaries of multinational companies (MNCs). this study analyzes data gathered through coordinated surveys of MNC subsidiaries in Canada, Ireland, and the United Kingdom, and tests the extent to which union status and double-breasting depend on home-country variation, host-country influences, and particular organizational characteristics. the authors find support for a combination of effects on both union status and double-breasting. further analyses test explicit variations on union status within each host context and support arguments that effects depend on the particularities of national industrial relations regimes. t he relationship between multinational companies (MNCs) and union status across different employee representation regimes has generated much interest among employment and industrial relations (IR) scholars. Employee representation structures are deeply embedded in the institutional arrangements of political economies. Scholars often view MNCs, however, as exogenous to national path dependencies; MNCs are arguably carriers of practices and understandings forged in other contexts. Equally, these practices may also vary by firm characteristics and organizational policies. this confrontation between the logics of MNCs and different employee
