As the public sector has modernised and sought to become more efficient and cost-effective, the effective and strategic management of people has received increasing prominence and there have been calls for the HR function to play a more strategic role. However, not much is known about whether the role of the HR function has changed substantively. In this paper, we present empirical evidence from six matched-pair public sector organisations in the UK to assess whether HR functional roles have changed, as envisaged, into a model more akin to the private sector. The findings highlight the complex and often contradictory nature of HR functional roles, and suggest that new and more strategic roles have not replaced traditional approaches but, rather, have been grafted on, giving rise to a variety of hybrid HR forms.
