Researches into the relationship between culture and management practices are recently dominating the management practices literature especially with the current impact of globalisation, multi-nationalisation and internationalisation of businesses. This study examines the impact of culture on management practices with special reference to employment relations practices in Nigeria and the United Kingdom. This was achieved through a case study of employment relations practice in Cadbury (Nigeria) Plc and Cadbury (UK) Plc while employing semi-structured interviews. A review of the extant literature on culture and management practices revealed a dearth of literature on comparative study of employment relations practice (and other management practices) between the developed (eg UK) countries and the developing countries (eg Nigeria). Previous researches were focussed mainly on comparative study of employment relations practice (and other management practices) between the economically developed countries of the world. This study is an attempt to fill the gap in the literature. The study relied on Cadbury Worldwide (Cadbury UK and Cadbury Nigeria) as the case study. The findings relying on narrative analysis established a strong relationship between culture and employment relations practice (and other management practices). The study concludes that it is impossible to formulate a template of employment relations practices (and other management practices) with the intention of transferring same from one country or cultural area to another country or another cultural area.
