The issues of duality, paradox, ambiguity and balance dominate the human resource literature. Arguably, it was Karen Legge who started this debate back in 1978, and almost thirty years on we are finding increasing evidence of the dualities, paradoxes and ambiguities entailed in human resource management (HRM) today. This e-book furthers the debates in this field, encouraging a constructive review of HRM theories. The papers in the e-book were all presented at the Dutch HRM Network Conference 2007, hosted by Tilburg University, Department of HR Studies.
