The year 2018 is the 150 anniversary of the Tata group. This article is an attempt to examine the role of spiritual family values in shaping Tata as a sustainable business. Jamsetji Nusserwanji Tata, the founder of Tata, was a trained Parsi priest, who was greatly influenced by Humata or good thoughts, Hukhta or good words, and Hvarshta or good deeds toward others. Since its founding in 1868, the Tata leadership legacy has persistently followed those watchwords of the Zoroastrian faith. (...) The extant workplace spirituality literature posits that the role of spiritual and religious values is vital for organizations and individuals to prosper. Employing historical data and biographical method, we trace the history of Tata to examine the causal mechanism between spirituality and sustainable business, under the influence of stakeholder concept, sustainability and family values-based leadership. Implications for research and practice are discussed. (shrink)
