Human resource management (HRM) in public organizations is changing as there are numerous policy, procedural and structural reforms underway. Human resource management studies have focused primarily at the state and federal levels, with relatively fewer comprehensive views of county governments. This article looks at human resource management roles, structures and practices from the perspective of county government using data from the Government Performance Project. The article describes approaches to reforms, the role and structures of the central HRM department, and the range of HRM practices related to selection, training, classification and compensation. The study finds that while different innovations and reforms have been adopted, county governments continue to function somewhat traditionally, leaving many opportunities for additional reforms to improve county governance.
