Under the present waves of merger and acquisition, many multinational firms have to achieve several goals, sometimes in conflict, and so there is a great need to effectively manage the ever leaner and more divergent work-force. The HRM function in multinational firms is developing to fulfil this need by helping firms to use the knowledge employees from all regions have of their tasks through human intelligence deployment. Contributors focus particularly on the challenges faced by firms with multinational subsidiaries, within which HRM systems have often been operating in very different ways, and they show that there is value in identifying and understanding those differing approaches. This book will help managers of multi-national firms to deploy their staff more effectively and shows how human intelligence deployment may be the way to improve long-term profitability of their firms if considered as part of a global HR strategy.
