The present study investigated the effect of organisational culture on high attrition of employees in business process outsourcing (BPO) sector in India. The study has been conducted in three strata comprised of 15 BPO units in and around Chandigarh. An attempt has been made to establish a relationship between openness, confrontation, trust, authenticity, proaction, autonomy, collaboration and experimenting (OCTAPACE) dimensions of organisational culture and turnover intentions of employees. Regression analysis was employed to test the research hypotheses. Results revealed that turnover intentions are particularly sensitive to six dimensions of organisational culture viz. proaction, confrontation, experimentation, trust, authenticity and collaboration. But the results failed to support the relationship of openness and autonomy dimensions of organisational culture with turnover intentions. This study contributes to a better understanding of the influence of organisational culture on the turnover intentions among employees in the BPO sector.Reference to this paper should be made as follows: Dwivedi, S., Kaushik, S. and Malodia, L.
