Abstract
The aim of this paper was to propose human care practices (HCPs) and knowledge management practices (KMPs) as sustainable human resource management practices (SHRMPs) that enhance the worker productivity in the tea industry in Sri Lanka. Un-structured interviews of 15 senior level managers of well performing tea estates in Sri Lanka reported HCPs and KMPs as sustainable HR practices, which provide a strong foundation for consistent enhancement of worker productivity in tea industry. These outcomes are based on the premise of Psychological Contract (Argyris, 1960; Rousseau, Tomprou& Montes, 2013; Savarimuthu and Rachael, 2017) and Social Exchange (Blau, 1964; Redmond, 2015) theories. The theoretical and policy implications are also discussed.
